Pl sql block doesn't do anything

I have a pl/sql block and it doesn't do anything why?
Code is as follows:
DECLARE @day varchar(10)
BEGIN
set @day='select to_char('sysdate','DAY') from dual;
PRINT @day
END;
Any ideas would be highly appreciated.
Thanks !

It is Oracle 11g DB. Not SQL server.Your Database is Oracle but your code is T-SQL and not PL/SQL
DECLARE
@day varchar(10)
BEGIN
set @day='select to_char('sysdate','DAY') from dual;
PRINT @day
END;
/ You cannot just copy past a T-SQL code into Oracle and expect it to Run.
You need to stop writing code and start learning PL/SQL. You can start with [url http://docs.oracle.com/cd/B19306_01/appdev.102/b14261/toc.htm]Oracle Database PL/SQL Users Guide and Reference
A PL/SQL code would look like this
set serveroutput on
delcare
   my_day varchar2(10);
begin
   select to_char(sysdate, 'DAY') into my_day
     from dual;
   dbms_output.put_line(my_day);
end;

FETCHING OUTPUT VALUE FROM PL/SQL BLOCK

hI aLL,
I'm working on ODP.NET. I'm executing below pl/sql command. while executing this command in pl/sql it's showing the output which is an xml.
declare
xmloutput xmltype;
xmldata varchar(32767);
teid t_id := t_en_id( 'L','L',NULL,12121,'ABC','USER','N');
tgetinfo to_info := NULL;
RETVAL NUMBER;
begin
RETVAL := GET_DTLS(teid,tgetinfo);
dbms_output.put_line(RETVAL);
xmldata := tgetinfo.XML_info.getclobval();
dbms_output.put_line(xmldata);
end;
I passed above command in string variable for passing in code. like below
string StrQry = "";
StrQry += "declare \n";
StrQry += "xmloutput xmltype; \n";
StrQry += "xmldata varchar(32767); \n";
StrQry += "teid t_id := t_en_id( 'L','L',NULL,12121,'ABC','USER','N'); \n";
StrQry += "tgetinfo to_info := NULL; \n";
StrQry += "RETVAL NUMBER; \n";
StrQry += "begin \n";
StrQry += "RETVAL := GET_DTLS(teid,tgetinfo); \n";
StrQry += "dbms_output.put_line(RETVAL); \n";
StrQry += "xmldata := tgetinfo.XML_info.getclobval(); \n";
StrQry += "dbms_output.put_line(xmldata); \n";
StrQry += "end; \n";
I'm passing output parameter ":temp" for this command. I want to catch output xml in ":temp" variable
which is varchar2 type.
Added below line before printing xmldata;
StrQry += ":temp := xmldata; \n";
cn.Open();
OracleCommand cmd = new OracleCommand(StrQry, cn);
cmd.Parameters.Add(":temp", OracleDbType.Varchar2, 32767, ParameterDirection.Output);
cmd.ExecuteNonQuery();
But which executing through c# code it's showing the below error.
Oracle.DataAccess.Client.OracleException ORA-06502: PL/SQL: numeric or value err
or: character string buffer too small
ORA-06512: at line 11 at Oracle.DataAccess.Client.OracleException.HandleError

How can i get the output to output variable ":temp".
Pls help.
Ideas are appreciated.

Your PL/SQL block isn't returning anything. DBMS_OUTPUT is, at best, a way of debugging code, not passing data around. Assuming you configure and enable an appropriately sized buffer, I suppose your ODP.Net application could make DBMS_OUTPUT.GET_LINE calls to retrieve the XML. But that's not not a way to design an application.
If you want a PL/SQL block that returns XML, you'll need to create a function and have the function return the XML (you could also create a procedure with an OUT parameter in which you could return the XML).

How to test for différent Select into a single PL/SQL block ?

Hi,
I am relatively new to PL/SQL and I am trying to do multiple selects int a single PL/SQL block. I am confronted to the fact that if a single select returns no data, I have to go to the WHEN DATA_NOT_FOUND exception.
Or, I would like to test for different selects.
In an authentification script, I am searching in a table for a USER ID (USERID) and an application ID, to check if a user is registered under this USERID for this APPLICATION.
There are different possibilities : 4 possibilities :
- USERID Existing or not Existing and
- Aplication ID found or not found for this particular USERID.
I would like to test for thes 4 possibilities to get the status of this partiular user regardin this application.
The problem is that if one select returns no row, I go to the exception data not found.
In the example below you see that if no row returned, go to the exception
DECLARE
P_USERID VARCHAR2(400) DEFAULT NULL;
P_APPLICATION_ID NUMBER DEFAULT NULL;
P_REGISTERED VARCHAR2(400) DEFAULT NULL;
BEGIN
SELECT DISTINCT(USERID) INTO P_USERID FROM ACL_EMPLOYEES
WHERE USERID = :P39_USERID AND APPLICATION_ID = :APP_ID ;
:P39_TYPE_UTILISATEUR := 'USER_REGISTERED';
EXCEPTION
WHEN NO_DATA_FOUND THEN
:P39_TYPE_UTILISATEUR := 'USER_NOT_FOUND';
END;I would like to do first this statement :
SELECT DISTINCT(USERID) INTO P_USERID FROM ACL_EMPLOYEES
WHERE USERID = :P39_USERID Then to do this one if the user is found :
SELECT DISTINCT(USERID) INTO P_USERID FROM ACL_EMPLOYEES
WHERE USERID = :P39_USERID AND APPLICATION_ID = :APP_ID ;etc...
I basically don't want to go to the not found exception before having tested the 4 possibilities.
Do you have a suggestion ?
Thank you for your kind help !
Christian

Surely there are only 3 conditions to check?
1. The user exists and has that app
2. The user exists and doesn't have that app
3. The user doesn't exist
You could do this in one sql statement like:
with mimic_data_table as (select 1 userid, 1 appid from dual union all
                          select 1 userid, 2 appid from dual union all
                          select 2 userid, 1 appid from dual),
-- end of mimicking your table
         params_table as (select :p_userid userid, :p_appid appid from dual)
select pt.userid,
       pt.appid,
       decode(min(case when dt.userid = pt.userid and dt.appid = pt.appid then 1
                       when dt.userid = pt.userid then 2
                       else 3
                  end), 1, 'User and app exist',
                        2, 'User exists but not for this app',
                        3, 'User doesn''t exist') user_app_check
from   mimic_data_table dt,
       params_table pt
where pt.userid = dt.userid (+)
group by pt.userid, pt.appid;
:p_userid = 1
:p_appid = 2
    USERID      APPID USER_APP_CHECK
         1          2 User and app exist
:p_userid = 1
:p_appid = 3
    USERID      APPID USER_APP_CHECK
         1          3 User exists but not for this app
:p_userid = 3
:p_appid = 2
    USERID      APPID USER_APP_CHECK
         3          2 User doesn't exist

Bind Variable in SELECT statement and get the value in PL/SQL block

Hi All,
I would like pass bind variable in SELECT statement and get the value of the column in Dynamic SQL
Please seee below
I want to get the below value
Expected result:
select distinct empno ,pr.dept   from emp pr, dept ps where   ps.dept like '%IT' and pr.empno =100
100, HR
select distinct ename ,pr.dept   from emp pr, dept ps where   ps.dept like '%IT' and pr.empno =100
TEST, HR
select distinct loc ,pr.dept   from emp pr, dept ps where   ps.dept like '%IT' and pr.empno =100
NYC, HR
Using the below block I am getting column names only not the value of the column. I need to pass that value(TEST,NYC..) into l_col_val variable
Please suggest

Thanks Billy, Would you be able to suggest any other faster method to load the data into table. Thanks,
As Mark responded - it all depends on the actual data to load, structure and source/origin. On my busiest database, I am loading on average 30,000 rows every second from data in external files.
However, the data structures are just that - structured. Logical.
Having a data structure with 100's of fields (columns in a SQL table), raise all kinds of questions about how sane that structure is, and what impact it will have on a physical data model implementation.
There is a gross misunderstanding by many when it comes to performance and scalability. The prime factor that determines performance is not how well you code, what tools/language you use, the h/w your c ode runs on, or anything like that. The prime factor that determines perform is the design of the data model - as it determines the complexity/ease to use the data model, and the amount of I/O (the slowest of all db operations) needed to effectively use the data model.

Can some one please tell me what is the problem in the below pl/sql block

Hi, I have problem with the following pl/sql block, I need this with bulk operation.
-- Assume the following scenario, we are validating dept (master) and emp(child) which are my temporary tables and updating the status back to
-- dept ( for all the validation errors, even if we have any validation at child it has to update the header record with error message),
-- upon successful validation insert the data into dept3, and emp3 interms of batches
-- I have give the sample example with dept and emp, but i have around 10 million records which has around 30-40 validations,
-- I would like to process them in terms of batches using bulk collection as this would do fast processing
-- Can some one please tell me how to insert them in terms of bulk with every set of 1000 records in each batch in this example,for every set of 1000 records
-- i need update batch id with unique number in dept table
-- with current data i can have 50 batches , I need to pass, deptno as parameter to my emp cursor.
-- can some one please tell me how to make this validation and insertion more efficient. so that while inserting the data for every batch it should insert batch id
-- Tried with LIMIT clause as well but not working
-- I am correcting the code as per your comments Request you to please suggest me so that I can correct , I am new to PL/sql, started learning now.

Hi, I have problem with the following pl/sql block
Well, as Hoek already said, that is the understatement of the century.
I can't be absolutely certain but I think that set of DDL and code that you posted has just about every possible error and design issue that there is! It would make an excellent addition to BluShadow's FAQs an an example of what NOT to do.
I don't think it is even possible to 'fix the basics first' as Hoek suggested. IMHO the first step needs to be to create a functional requirements document (FRD) that explains in detail WHAT needs to be done. That doc should also contain info about how any errors/recovery/restart is to be handled. It is premature to try to implement ANY solution without first knowing what is needed functionally.
Once the FRD is done you should do a walk-through based on your current architecture and sample data to make sure that the document really covers ALL of the steps that need to be performed and that it adequately explains how to deal with any processing or data issues that might arise.
The next document you need is the TRD - Technical Requirements Doc that covers the different technical implementions of the FRD that can be done and the advantages/disadvantages of each.
Then you can start working on a prototype.
1. The DDL you posted isn't coherent - there are CREATE table statements and then later ALTER statements that add additional columns. There doesn't appear to be any reason for not including ALL of the columns in the CREATE table statement.
2. You are using PL/SQL types instead of SQL types. That makes it impossible to use those types in SQL statements and makes it much more difficult to test since it is much easier to test a query in SQL (e.g. using sql*plus) that to embed the query in PL/SQL.
3. You are defining the same type twice but giving it different names.
TYPE dept_t
   IS
      TABLE OF dept%ROWTYPE
         INDEX BY binary_integer;
TYPE dept_i_t
   IS
      TABLE OF dept%ROWTYPE
         INDEX BY binary_integer;
Those are both based on the same DEPT table! Why the duplication?
Also you are using associative arrays instead of just using nested tables. Get rid of the INDEX BY clause.
4. You have some serious architectural and data model issues
-- Assume the following scenario, we are validating dept (master) and emp(child) which are my temporary tables and updating the status back to
-- dept ( for all the validation errors, even if we have any validation at child it has to update the header record with error message),
Why would you do that? You say 'it has to update the header record ...'. Says who? That is just one indication that you are trying to implement a 'solution' before you have adequately defined the 'problem'.
Typically you would NOT alter any of the data tables; any validation errors/issues would get inserted into a table specifically designed to hold/log those issues. That table would contain key field values to correlate with the source of the error.
Those 'master' and 'child' entities are two SEPARATE things. Issues with a 'master' row have NOTHING to do with any possible child rows.
And issues with a 'child' row have NOTHING to do with any possible master rows. The ONLY connection between 'child' and 'master' is the foreign key that correlates them.
So you don't necessarily have to validate the 'child' rows in sync with their 'master' row. In many cases you would have a procedure that performs validation of the entire set of 'master' rows and log those issues/problems. You would use a different procedure to validate the entire set of 'child' rows and log their issues.
Those validation procedures can often work with ALL of the data using SQL statements instead of bulk processing.
5. You are using loop constructs that are not valid for the type of processing you are using
LOOP
    FETCH c1 BULK COLLECT INTO hdr_tbl;
    EXIT
WHEN c1%NOTFOUND;
END LOOP;
There can be NO exit since the bulk collect with either get EVERYTHING or NOTHING. Possibly that is just a holdover from your attempt to use the LIMIT clause but you removed that clause from the FETCH; I don't know.
There is so much wrong with what you posted it is really rather pointless to try to 'fix' it.
I suggest you start over and clarify and DOCUMENT the actual requirements without prejudice about the solution that someone seems to want to force on you.

PL/SQL Block for Data Formatting

I have created a Report that will pull all times that a person clocks in and clocks out. It works great but now accounting wants me to do some "conditional formatting" that can't be done by Report's built in conditional formatting capabilities. I talked to tech support yesterday and they suggested a PL/SQL block to format my times to do what accounting needs. Here is the skinny: All times in the database are done in 100ths of an hour. I need to the times up or down to the next quarter hour depending on when they clocked in. If they clocked in one minute late, it rounds down the the previous quarter hour and anything later and it rounds up. Can someone help me? Thanks, Jeremy

In the data model, enter your query and create the groups you need.
Let's say you have the number column my_time in a group named g_times.
Then create a formula column in the group g_times and look at its
properties. Change the name to cf_time.
Click on the property PL/SQL-Formula, and in the pl/sql editor you can
write something like
function CF_TIMEFormula return Number is
begin
return trunc((:my_time + 0.23) * 4) / 4;
end;As you see, you can access query columns by using the colon.
Afterwards, you can display :cf_time in your Layout model.

Pl/sql block on block trigger

I have a pl/sql block in when-new-block-instance trigger on forms 10g.
Basically, these trigger fires after user selection of the search criteria block.
Exist one condition which is totaly important:
One of the search criteria is a list of document type. So the user, can check one, all or none of the doc types.
See this pictures:
doc type options: TRRLS, ADS, SIQD
If the user check only the TRRLS, the next block will display only the record match the doc type selected. If the user check none doc type, all the record will be displayed.
For those purpose, in the trigger I talk before (when new block instance) in the results block, I use two cursors, one for all the record (if the user check none doc type). And the other cursor for the records with specific doc type.
The first one works just fine, but the second one, do nothing. Part of the where in the cursor is the following:
where ........... and
dim.doc:typ IN (:global.doc_typ_where_clasue) and
The value of the :global.doc_typ_where:clause is the list of all the doc type selected by the user. In example, if the user check TRRLS and ADS, the global variable will have 'TRRLS', 'ADS'.
But it doesn't work..... I don't know why....
Any idea to pass a list of doc to a cursor and use in a where clause dynamically.
thanks a lot,
abdel.

If you search for "dynamic in list" on http://asktom.oracle.com/ you'll find a solution to exactly the same problem you're facing. The solution is:
1. Strip the string into an array
2. Use the array in the where clause.
But maybe you can also create your own where clause and use that one by setting set_block_property( <block>, onetime_where, <where clause>)

Why named parameter can't be used multiple times in PL/SQL block in JDBC

with the following PL/SQL block, when I run int in JDBC, I get an error,
it says, The number of parameter names does not match the number of registered parameters.
if all named parameters are used only once, then my program works fine.
My old program uses Oracle Forms to run the attached PL/SQL block correctly, I just want to run them in JDBC without more efforts, I don't want to rewrite all PL/SQL blocks.
Does oracle driver support this case? why the PL/SQL block can work in Oracle Forms but failed in JDBC?
Can we have an another solutions to avoid rewriting the PL/SQL block to stored procedure?
if I use following SQL:
BEGIN if :q is null then :q := 'X'; else :q := 'Y'; end if; END;
, Using java program:
import java.sql.*; public class RunPLSQLBlock { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL = "BEGIN if :q is null then :q := 'X'; else :q := 'Y'; end if; END;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter("q", Types.VARCHAR); stmt.setString("q", "A"); stmt.execute(); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
in the coding, only "q" registered, I got:
java.sql.SQLException: The number of parameter names does not match the number of registered praremeters at oracle.jdbc.driver.OracleSql.setNamedParameters(OracleSql.java:314) at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:10096) at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:5693) at RunPLSQLBlock.main(RunPLSQLBlock.java:28)
now, tried to register 3 indexes, changed fragments are below.
import java.sql.*; public class RunPLSQLBlock { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL = "BEGIN if :q is null then :q := 'X'; else :q := 'Y'; end if; END;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter(1, Types.VARCHAR); stmt.registerOutParameter(2, Types.VARCHAR); stmt.registerOutParameter(3, Types.VARCHAR); stmt.setString(1, "A"); stmt.execute(); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
now error changed to:
java.sql.SQLException: ORA-01006: bind variable does not exist at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:457) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:400) at oracle.jdbc.driver.T4C8Oall.processError(T4C8Oall.java:926) at oracle.jdbc.driver.T4CTTIfun.receive(T4CTTIfun.java:476) at oracle.jdbc.driver.T4CTTIfun.doRPC(T4CTTIfun.java:200) at oracle.jdbc.driver.T4C8Oall.doOALL(T4C8Oall.java:543) at oracle.jdbc.driver.T4CCallableStatement.doOall8(T4CCallableStatement.java:208) at oracle.jdbc.driver.T4CCallableStatement.executeForRows(T4CCallableStatement.java:1416) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1757) at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:4372) at oracle.jdbc.driver.OraclePreparedStatement.execute(OraclePreparedStatement.java:4595) at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:10100) at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:5693) at RunPLSQLBlock.main(RunPLSQLBlock.java:26)
, now tried register only 1 position like below,
CallableStatement stmt = con.prepareCall(SQL);   stmt.registerOutParameter(1, Types.VARCHAR);   stmt.setString(1, "A");   stmt.execute();
, it says:
java.sql.SQLException: Missing IN or OUT parameter at index:: 2 at oracle.jdbc.driver.OraclePreparedStatement.processCompletedBindRow(OraclePreparedStatement.java:2177) at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:4356) at oracle.jdbc.driver.OraclePreparedStatement.execute(OraclePreparedStatement.java:4595) at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:10100) at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:5693) at RunPLSQLBlock.main(RunPLSQLBlock.java:26)
, now let try a OK case, which use all named parameters only once. coding like below, SQL and Java listed below.
BEGIN if :q is null then :r := 'X'; else :s := 'Y'; end if; EXCEPTION   WHEN NO_DATA_FOUND THEN     NULL; END;
import java.sql.*; public class RunPLSQLBlock { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL = "BEGIN if :q is null then :r := 'X'; else :s := 'Y'; end if; END;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter("q", Types.VARCHAR); stmt.registerOutParameter("r", Types.VARCHAR); stmt.registerOutParameter("s", Types.VARCHAR); stmt.setString("q", "A"); stmt.execute(); System.out.println("Q :" + stmt.getString("q")); System.out.println("R :" + stmt.getString("r")); System.out.println("S :" + stmt.getString("s")); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
, the case give us the following output:
Q :A R :null S :Y
2nd part, I also tried another scheme, to use 'execute immediate', test code attached below, it also have errors.
begin execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out :q, out :r; end;
, Java Code:
import java.sql.*; public class RunDynamicSQL { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL ="begin execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out :q, out :r; end;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter("q", Types.VARCHAR); stmt.registerOutParameter("r", Types.VARCHAR); stmt.setString("q", "A"); stmt.execute(); System.out.println("Q :" + stmt.getString("q")); System.out.println("R :" + stmt.getString("r")); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
, the output is, we can find when parameter 'q' is IN OUT mode, we can't get its final value:
Q :null R :Z
, now I tried my workaround, it works fine by using a temporary variable, now my named parameter is split to 2 roles, one is for IN, another is for OUT, now I can get final out value.
declare q clob; r clob; begin q := ?; r := ?; execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out q, out r; ? := q; ? := r; end;
, my test java code,
import java.sql.*; public class RunDynamicSQL { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL ="declare q clob;r clob; begin q := ?; r := ?; execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out q, out r; ? := q; ? := r; end;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter(3, Types.VARCHAR); stmt.registerOutParameter(4, Types.VARCHAR); stmt.setString(1, "A"); stmt.setString(2, "A"); stmt.execute(); System.out.println("Q :" + stmt.getString(3)); System.out.println("R :" + stmt.getString(4)); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
, the output is expected,

Hi, thanks for your response, now I see, the named parameter is for stored procedure only, for PL/SQL block we name it placeholder name.
After cast my java.sql.CallableStatement to oracle.jdbc.OracleCallableStatement, I can find setStringAtName,
now, I have only one question:I can't find corresponding methods for registerOutputParameter, how we fetch output value?
I tried to callableStatement.getString("q"); it reports errors, but there are no ordinal binding in my source code, does placeholder names doesn't support OUT mode?
Java:
CallableStatement stmt = con.prepareCall("BEGIN if :q is null then :r := 'X'; else :s := 'Y'; end if; END;");
oracle.jdbc.OracleCallableStatement call = (oracle.jdbc.OracleCallableStatement) stmt;
call.registerOutParameter("q", Types.VARCHAR);
call.registerOutParameter("r", Types.VARCHAR);
call.registerOutParameter("s", Types.VARCHAR);
call.setStringAtName("q", "A");
call.setStringAtName("r", "A");
call.setStringAtName("s", "A");
call.execute();
System.out.println("Q :" + call.getString("q"));
</Java>
<output>
java.sql.SQLException: 不允许的操作: Ordinal binding and Named binding cannot be combined!

     at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:146)
     at oracle.jdbc.driver.OracleCallableStatement.getString(OracleCallableStatement.java:2834)
     at RunPLSQLBlock.main(RunPLSQLBlock.java:33)
</output>by the way, in my below-mentioned SQL 'problematic', when my code uses 'execute immediate' and use placeholder names in IN OUT mode, we always get NULL value (i.e. ':q'), but we can get final value of ':r' when ':r' is OUT mode only; now I get a workaround attached in below-mentioned 'my workaround' block, which split the IN OUT roles to 2 parts, it can work now;
It seems that the difference between 'problematic' and 'my workaround' imply that there are something work unexpectedly when the driver process the placeholder names, because 'my workaround' and ':r in problematic case' make sure the 'execute immediate' returned output values correctly, unluckly driver layer can't get return values.
<SQL name = 'problematic'>
begin
     execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;'
     using in out :q, out :r;
end;

Pl/sql block returning sql query.

Hello,
I am using oracle 10g apex 3.2 version.
I am using the following return statement inside my report which is pl/sql block returning sql query.
declare
pid varchar2(100);
begin
return 'select patient_id_code from t_files_data_exp where patient_id_code not in pid';
end;
How am i suppose to mention the pid inside the return stmt i mean with any quotes or anything? because the above return stmt gives error
"1 error has occurred
Query cannot be parsed within the Builder. If you believe your query is syntactically correct, check the ''generic columns'' checkbox below the region source to proceed without parsing. The query can not be parsed, the cursor is not yet open or a function returning a SQL query returned without a value."
Thanks

Hello,
I did exactly the way u told
declare
pid varchar2(100) := '(61092,61093)';
begin
return 'select patient_id_code from t_files_data_exp where patient_id_code not in ' || pid;
end;
patient_id_code is varchar2(100) only in table.
For this i am getting "invalid number error".
Thanks

SQL Query (PL/SQL Function Body returning SQL query) doesn't return any row

I have a region with the following type:
SQL Query (PL/SQL Function Body returning SQL query).
In a search screen the users can enter different numbers, separated by an ENTER.
I want to check these numbers by replacing the ENTER, which is CHR(13) || CHR(10) I believe, with commas. And then I can use it like this: POD IN (<<text>>).
It's something like this:
If (:P30_POD Is Not Null) Then
v_where := v_where || v_condition || 'POD IN (''''''''||REPLACE(''' || :P30_POD || ''', CHR(13) || CHR(10), '','')||'''''''''')';
v_condition := ' AND ';
End If;
But the query doesn't return any rows.
I tried to reproduce it in Toad:
select * from asx_worklistitem
where
POD IN (''''||REPLACE('541449200000171813'||CHR(13) || CHR(10)||'541449206006341366', CHR(13) || CHR(10), ''',''')||'''')
==> This is the query that does't return any rows
select (''''||REPLACE('541449200000171813'||CHR(13) || CHR(10)||'541449206006341366', CHR(13) || CHR(10), ''',''')||'''')
from dual;
==> This returns '541449200000171813','541449206006341366'
select * from asx_worklistitem
where pod in ('541449200000171813','541449206006341366');
==> and when I copy/paste this in the above query, it does return my rows.
So why does my first query doesn't work?
Doe anyone have any idea?
Kind regards,
Geert

Thanks for the help.
I made it work, but via the following code:
If (:P30_POD Is Not Null) Then
v_pods := REPLACE(:P30_POD, CHR(13) || CHR(10));
v_where := v_where || v_condition || 'POD IN (';
v_counter := 1;
WHILE (v_counter < LENGTH(v_pods)) LOOP
v_pod := SUBSTR(v_pods, v_counter, 18);
IF (v_counter <> 1) THEN
v_where := v_where || ',';
END IF;
v_where := v_where || '''' || v_pod || '''';
v_counter := v_counter + 18;
END LOOP;
v_where := v_where || ')';
v_condition := ' AND ';
End If;But now I want to make an update of all the records that correspond to this search criteria. I can give in a status via a dropdownlist and that I want to update all the records that correspond to one of these POD's with that status.
For a region you can build an SQL query via PL/SQL, but for a process you only have a PL/SQL block. Is the only way to update all these records by making a loop and make an update for every POD that is specified.
Because I think this will have a lot of overhead.
I would like to make something like a multi row update in an updateable report, but I want to specify the status from somewhere else. Is this possible?

I recently got an extension cord for my ipad charger and the first time I used it it worked and now when I plug it in to my ipad It doesn't do anything. What do I do?

I recently got an extension cord for my ipad charger and the first time I used it it worked and now when I plug it in to my ipad It doesn't do anything. What do I do?

I think that we all understood what you meant. If the extension cord is no longer working, then return it.
We are all trying to tell you that you can plug the power block into a standard household extension cord - using the short cord that came with the iPad - and there is no need for the extension cord that you bought.

Running a anonymous PL/SQL block

Hi,
I have created an anonymous PL/SQL block and saved it in a file. And I am now trying to run it from the sql prompt using @.
But this doesn't seem to be working. I get a wierd number as output and then it hangs.
This is not the case if I copy paste the anonymous block. In this case I get the correct output.
Please assist as to whether it is possible to run it using @ as it is important for me to do so..

Hi,

How to use Pl/sql block to edit check user input

Hi,
Please advise on PL/SQL Block code that could be used to Check User input from within a Loop and proceed conditionally based upon User Supplied compliant Input. Thanks in advance.

You could use the ACCEPT to get user input and then assign the input to a variable that could then be verified.
I believe that anything is possible because we don't yet have proof that it is not!
I do have code that can accept user input. Is it PL/SQL code? Sybrand was clearly talking about PL/SQL:

Pl/sql is for server side code, it is not a front end tool, and it is incapable of the functionality you describe.If you do have PL/SQL code that accepts user input, please post an example. A lot of people, including me, would be very interested.
Pass the user-input value to a variable and then assign that value to another variable from within a Declare of a PL/SQL Block.
The opportunity here is to figure a way to loop with user input until desired input is entered by the user before proceeding with the code. I'm using PL/SQL Block because I don't want the code to persist. I just want to run it as part of database configuration procedure. ThanksIt sounds like you're talking about SQL*Plus, which is a very poor tool for looping or branching.
It's possible, but it's not pretty. The following thread shows one way of looping in SQL*Plus:
Re: How to give the different values to runtime parameters in a loop?

Use Chains, or PL/SQL Block of calls.

I currently have a half dozen cron jobs that kick off different batches of processing. Originally, these were generally a sequence of C programs that did different operations (fetch student info from student record system and load into IdM system, process directory changes, etc). Over the years, most of the program logic has been rewritten as PL/SQL packages and the cron jobs basically drop into SQL*PLUS and do things like:
prompt "Do Spbpers delta"
execute simon.employee_maint.Spbpers_Delta;
commit;
prompt "Do People.Update_From_Employees"
execute simon.People_Maint.Update_From_Employees;
commit;
prompt "Do SGBSTDN_Full"
execute Simon.Bstudent_Maint.Sgbstdn_Full;
commit;
prompt "Do SPRIDEN_Full (Student)"
execute Simon.Bstudent_Maint.Spriden_Full;
These procedures generally connect to other Oracle databases and get or push data around, and are hitting a number of different databases. The biggest of these scripts has 45 execute statements in it. (This script started in 1992.....)
Anyway, we are getting some issues with and it is time to clean things up. This is my first foray into Scheduler and I am hoping to get some philosophical guidance on how best I should restructure things. One obvious thing, is to break up the big script into a couple of smaller ones. In some cases, order matters and in other, it doesn't - although I would prefer not to have several jobs hitting the admin system at the same time.
I have been playing a bit with the scheduler, mostly via the EM web interface, and have come up with a few questions - some pretty specific, others more stylistic.
1) Procedures as jobs - it seemed to want stand alone procedures, and NOT procedures that were part of a package. True?
2) How fine grained should I make the steps in a chain? For example, I call 5 procedures in the same package (student_maint), each to to some specific aspect of the processing (each represents a different source table). Should I create 5 programs, and make them 5 steps in the chain, or just have 5 calls in a PL/SQL block in one program?
3) I don't care what order these 5 run in, but I don't want more than one running at once - thoughts on approaches to this?
4) I will on occasion want to turn off sets of these tasks (like when the remote system is going to be down for an upgrade) - how best to structure things to make this easy to do (and how do I do this?)
The Scheduler system seems to be a very rich and flexible environment, with a lot more options and features than I need, but I feel I should do more than just scheduling a single program with 45 procedure calls in it....

Hi,
I can try to answer some of these questions
1) Procedures as jobs - it seemed to want stand alone procedures, and NOT procedures that were part of a package. True?
False. The EM interface does have this restriction, but if you use dbms_scheduler directly there is no such restrisction. Even in the EM interface you can workaround this by using a PL/SQL block which calls the package procedure (although argument handling is a little less flexible this way).
2) How fine grained should I make the steps in a chain? For example, I call 5 procedures in the same package (student_maint), each to to some specific aspect of the processing (each represents a different source table). Should I create 5 programs, and make them 5 steps in the chain, or just have 5 calls in a PL/SQL block in one program?
The answer to this depends on what you are doing. If the 5 steps run serially one after the other, using one pl/sql block may be easier. If you want some pieces to run in parallel, then creating a simple chain is better. A bit more effort spent setting up the chain will result in much faster execution times if you can run pieces in parallel.
3) I don't care what order these 5 run in, but I don't want more than one running at once - thoughts on approaches to this?
This has come up on the forum a few times and there are basically two different approaches. One is to use dbms_lock to ensure that only one runs at a time. This is the easiest way and the way that I recommend.
The other way is to set up a job class with a resource consumer group and put into effect a resource consumer plan that specifies that only one session from that resource consumer group can run at a time. This is easily extensible to cases where you want 2 or more running at a time from a certain job class (which dbms_lock doesn't support).
Code on how to set this up and more discussion is located here
Run Jobs One After Another
4) I will on occasion want to turn off sets of these tasks (like when the remote system is going to be down for an upgrade) - how best to structure things to make this easy to do (and how do I do this?)
Jobs and programs can be disabled. But if a job or chain tries to run a disabled program it will result in a failure (though it will be retried if you say that the job can be restarted).
[ 5) ] The Scheduler system seems to be a very rich and flexible environment, with a lot more options and features than I need, but I feel I should do more than just scheduling a single program with 45 procedure calls in it....
The Scheduler was intended to accommodate a wide range of usage from simple one-off background tasks to complex sequences of interrelated tasks. As with any other software development you should use it in the simplest way possible that does what you need it to do.
Hope this helps. Feel free to post any further questions.

Stop a pl/sql block

Hi guys,
I would like to know, how can I stop an anonymus pl/sql block (what is the command, what rights do I need in order to execute the command, etc). We use TOAD for PL/SQL programming and I know that administrators can stop processes from Enterprise Manager.
But yesterday I started a block which is in an infinite loop and the administrator is on holiday, and the table is growing bigger and bigger and the tablespace will be full sooner or later.
So help pls.
Thanks,
Gabor

TOAD has a cancel button for SQL commands, but for PL/SQL blocks it doesn't show up.
The tablespace will fill up certainlly for monday, but it happened me for several times that I wanted to stop a pl/sql script and each time I had to call the administration. This is what I don't want to do all the time, so it would be nice to have the right to stop my bad PL/SQL scripts myself.
A different question whether the administrator will grant me those rights to stop a PL/SQL script. But maybe , because we work on a developer server, not on the real one.
Regards,
Gabor
