Use of Run_product in Pl/sql block written in forms 5.0

I am using Run_product built-in in forms 5.0 to make a call to reports runtime. This built-in is being called in a loop to make Payslip report for nearly 2000 employees.
First of all on running the report for 9 or 10 th employee , the error was given 'MAX OPEN CURSORS EXCEEDED'. to remove this error, settings were changed in init.ora to increase Open_cursors parameter. Now the above error is not coming but after creating 8-9 reports it gives error Numeric or Value error. This error keeps coming for all the reports after that. However this error is coming in an inconsitent manner. One time it gives error for some employees but doesn't gives that error for the same employees next time.

thanks !
I could find out few postings on the same topic in the same forum. that answers my question.
best regards,

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:

, 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:112)
     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;
</SQL>
<SQL name='my workaround'>
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;

Let me know how can i include accept stmt in Pl/SQL block
Thanks

You're missing a fundamental concept here.
PL/SQL = embedded 4GL programming language in the Oracle database.
SQL*Plus = CLI (Command Line Interface) client for an Oracle database.
The ACCEPT command is a SQL*Plus command. Not a PL/SQL command.
The PL/SQL engine sits inside the Oracle Server Process that services your client (SQL*Plus) session. That server process does not know who/what/where you are as a physical client. It does not know what platform and o/s you are using. It does not know what client you are using. It is after all a server process and should not and need not to know that.
Nor can that Oracle Server Process running on the Data Server Platform access you client's hard drive, keyboard, mouse, screen, printer and so on.
PL/SQL running in this Oracle Server Process therefore cannot read your keyboard to accept end-user input. PL/SQL therefore cannot write data to your screen.
You need to make a clear distinction between SQL*Plus (a client) and Oracle PL/SQL (the server).

Made one Link to /usr/lib

Nikolai,
I have created a simple process flow which only calls the external process. The script is on the same host as the process flow is deployed to.
I have used two diffent values for the command parameter.
1. I placed the full path of the file in the command parameter and left the script parameter blank:
COMMAND: /edwftp/ppas/scripts/ClearPPAS.sh
PARAMETER_LIST:
SUCCESS_THRESHOLD: 0
SCRIPT:
2.I placed the bash command in the command parameter and the full path in the script parameter.
COMMAND: /usr/bin/sh
PARAMETER_LIST:
SUCCESS_THRESHOLD: 0
SCRIPT: /edwftp/ppas/scripts/ClearPPAS.sh
Both of these appear to work as they print out the statements inside the script but the files that are supposed to be removed still remain.

Using Connect within a PL/SQL block

Hi,
I have a package, inside that i have many procedures & functions, in one of my procedure, i want to use [connect username/password] within a procedure.
This procedure is called by our client program (in VC++), they will just call the procedure name with parameters, but the procedure should internally connect to one more user & perform some dba related operations, all these things are done in the procedure only, clint will not be aware of the internal operations.
I tried to give connect within the procedure,
it gives an error Invalid SQL stmt while compiling the package. Is there any way to do this.
Pls. reply me back.
Bye

Spooling from PL/SQL Block

Hi,
Is it possible to do spooling from a pl/sql block.The spool cannot be the first command because I want to give the spool file name in a loop and each time the spool name should change based on the value.
I tried all possiblities,but I couldn't can anyone give me some idea on how to do this.
I cannot use UTL_FILE option ,because the client agreed only for spooling.
Is it possible to write the spool data is excel format..
Please find below an example of my requirement..
DECLARE
CurSor Cur_Designation IS
Select Designation from tbl_Designation;
N_Desig Cur_Designation%RowType;
Cursor Cur_Emp(Desig Number) IS
Select Emp_no,Emp_name
From Employee Where Emp_Designation = Desig;
N_Emp Cur_Emp%RowType;
BEGIN
Open Cur_Designation ;
Loop
Fetch Cur_Designation INTO N_Desig;
EXIT WHEN Cur_Designation %NOTFOUND;
--Here I want to give the spool file name
Spool --Should be designation name
Open Cur_Emp(N_Desig.Designation);
Loop
Fetch Cur_Emp INTO N_Emp ;
EXIT WHEN Cur_Emp %NOTFOUND;
-- All employee details I need to come to log file
End Loop;
Close Cur_Emp;
End Loop;
Close Cur_Desingnation;
End;
Please advice me how to do this..
Thanks,
Bindu

you can't use SPOOL inside PLSQL
you may use dbms_output calls in PLSQL
so create a procedure test2 instead of sqlscript test2 and you will be fine
rem =========== procedure test2 ================
create or replace
procedure test2 (p_param number) is
begin
             dbms_output.enable (1000000);
             dbms_output.put_line('A' || chr(9) || 'B' || chr(9) || 'C' ) ;

--step1
update students
set description = new description
where student_id = 1000
--step2
select description into v_old_description where student_id = 1000;
end loop;
In step2 when I am reading the record I am getting the new description which is expected.
My question is how can I get the old description. i-s the value of description which was before step1.
Thanks

No, you perform an update, so the old value is overwritten in the database.
If you really want to use sql, and I don't see why in your example, you can try [flashback query|http://www.oracle.com/technology/deploy/availability/htdocs/Flashback_Overview.htm] .

Stored Procedure Vs PL-SQL Block

Hi,
I came across an interesting problem last week. Fortunately, I was able to solve it or find an acceptable workaround for myself. But wanted to get some clarification from the experts. So posting it here.
Also, I am new to Orcle, so please excuse any shortcomings in the post.
My data model has following tables-
TABLE_PARENT (ID, other columns)
TABLE_CHILD (ID, other columns, PARENT_ID_FK)
Here, ID is the primary key column for the respective tables; PARENT_ID_FK is the foreign key referencing the ID column from the TABLE_PARENT.
I created a stored procedure programmatically (using MS Excel) to insert records in the two tables. The stored procedure has insert statements for an indefinite number of records in the parent table and for every such record, there's a corresponding record inserted in the child table. Here's the sample code.
BEGIN
/*first record*/
parent_id := MY_SEQUENCE_GENERATOR.NEXTVAL;
INSERT INTO TABLE_PARENT(ID, other columns) VALUES (parent_id, other values);
INSERT INTO TABLE_CHILD(ID, other values,parent_id );
/*second record*/
parent_id := MY_SEQUENCE_GENERATOR.NEXTVAL;
INSERT INTO TABLE_PARENT(ID, other columns) VALUES (parent_id, other values);
INSERT INTO TABLE_CHILD(ID, other values,parent_id );
/*third record*/
parent_id := MY_SEQUENCE_GENERATOR.NEXTVAL;
INSERT INTO TABLE_PARENT(ID, other columns) VALUES (parent_id, other values);
INSERT INTO TABLE_CHILD(ID, other values,parent_id );
/*and so on*/
END
When I run this stored procedure, I keep getting following exception intermittently-
ORA-02291: integrity constraint violated-parent key not found tips.
My thinking is that it comes because the insert statements are executing ahead of turn of the parent_id assignment statement. And this is happening possibly because of some parallelism that is taking place during the execution of the stored procedure, or, some sort of optmization that the DB server does (though erroneously) when it compiles the stored procedure.
I tried out everything that I could think of but it didn't go away. Finally, when I executed the same set of statements as a PL-SQL block, it worked fine.
To understand it better, I am looking for clarification on the following questions.
1) Why does the exception come with stored procedure but not with PL-SQL block? Is my reasoning given above correct (parallelism or some sort of optimization coming into play)?
2) If it is due to parallelism, how to run a Oracle stored procedure with defree of prallelism set to 1?
3) If it is due to optimization done by the compiler, how to instruct the compiler to not do any such optimization. Also, in any case, isn't it an error to optimize but lose program semantics?
4) Another question related to the same piece of work I have is to use transactions in the PL-SQL block, I had to explicitly COMMIT/ROLLBACK it in the code. In whatever references I had read, it was said that by default the transaction begins with BEGIN statement and commits with END. Also, it seems to work with a Stored Proedure though. So is it that a PL_SQL block needs explicity call to COMMIT/ROLLBACK to achive transactions but stored procedures do not?
Any inputs/clarifications will be much appreciated.
Thank you

Ok, your last couple of paragraphs were helpful. Here're the details that were missing in my earlier post.

INSERT INTO TABLE_CHILD (id, weight, PARENTID_FK)

*/* And so on for a few parent records more */*
END;
Can you throw some light on the exception I was seeing now? Note that when I changed from stored procedure to an anonymous block, it worked fine.
One correction in my earlier post is that as the code snippet shows, there are multiple inserts in the child table for every record inserted in the parent one.

Creating temporary table in pl/sql block problem

hello
i have a problem in creating and using temporary table in pl/sql block
please verify below block
begin
execute immediate 'create global temporary table alitemp1 (co_t varchar2(10),color varchar2(10))';
insert into alitemp1 (co_t,color) values ('001','red');
execute immediate 'DROP TABLE alitemp1';
end;
when i execute that block i will receive this error
insert into alitemp1 (co_t,color) values ('001','red');
ERROR at line 3:
ORA-06550: line 3, column 14:
PL/SQL: ORA-00942: table or view does not exist
ORA-06550: line 3, column 2:
PL/SQL: SQL Statement ignored
i think it because that alitemp1 table don't create
but two below block run fine
begin
execute immediate 'create global temporary table alitemp1 (co_t varchar2(10),color varchar2(10))';
execute immediate 'DROP TABLE alitemp1';
end;
begin
execute immediate 'create global temporary table alitemp1 (co_t varchar2(10),color varchar2(10))';
end;
select table_name from user_tables where table_name='ALITEMP1';
TABLE_NAME
ALITEMP1
it means that problem is when the below line exists in block
insert into alitemp1 (co_t,color) values ('001','red');
if may please guide me

In addition to the comments by Justin and 3360, you cannot do what you want the way you are doing it.
All objects referred to in a PL/SQL block must exist at the time the block is compiled. In your case, since it is an anonomous block, that is run time. Since you are dynamically creating the temporary table you need to refer to it dynamically as well. More like:
BEGIN
EXECUTE IMMEDIATE 'create global temporary table alitemp1 (co_t varchar2(10),
color varchar2(10))';
EXECUTE IMMEDIATE 'insert into alitemp1 (co_t,color) values (:b1,:b2)' USING '001', 'red';
EXECUTE IMMEDIATE 'DROP TABLE alitemp1';
END;However, don't do that it is a really bad idea. Just create the temporary table, if you really need it, once and use it in your processing.
In most cases, things that SQL Server needs temporary tables for can be done easily in Oracle with a single SQL statement,

How to use the WHENEVER SQLERROR EXIT statement in a PL/SQL block.

Hi,
I am getting the following error when trying to add the following statement in an PL/SQL block.
WHENEVER SQLERROR EXIT SQL.SQLCODE
[exec] ERROR at line 23:
[exec] ORA-06550: line 23, column 12:
[exec] PLS-00103: Encountered the symbol "SQLERROR" when expecting one of the

How can i use the above statement in the PL/SQL Block? I have only IF statement in that block( between BEGIN and END).
Thanks

Error while invoking webservice using UTL_HTTP from PL/SQL Block

Hi All,
I am invoking a webservice (SOAP Request) from a PL/SQL block using UTL_HTTP package.
I am able to send the complete request and am getting the required instance on the BPEL Console, but the process is erroring out while getting response back.
and the PL/SQL Block is ending in error mentioned below:
ERROR at line 1:
ORA-29266: end-of-body reached
ORA-06512: at "SYS.UTL_HTTP", line 1321
ORA-06512: at "APPS.CSM_BPEL_TEST_PKG", line 34
ORA-06512: at line 1
Package is completing successfully if i test in local DB and local BPEL.
But giving above error in client's.
Can anyone let me know what is the cause of this.
Thanks in advance

I got it working by making process Synchronous.
But with asynchronous process it is still same error.
Thanks...

Resolved: Use value from select list in pl/sql block

Hello,
I have a form with a select list: P18_BONUSTYPE, the values of which come from a LOV.
When the user clicks a button, a page process is used to insert a row into a table.
When I use the :P18_BONUSTYPE bind variable in my insert statement I get an error "Invalid number" I get an "Invalid number" error. I assume that APEX is using the displayed text in that bind variable, not its actual (html option) value.
I checked the HTML of the page, and the correct values are in the select list.
Can someone tell me how to get the value into a bind variable that can be used in a pl/sql block for a page process?
Thanks

Issue was a value in another item.

Did you tried changing the value using "to_number"? (i.e. to_number(:P18_BONUSTYPE)).
Max.

Using PL/SQL Block how do you check if the character string value is aA-zZ

I have a pl/sql block that I prompt the user for password and I load the string into an array and interrogate each index(entry) to see if it is "aA-zZ".
How can I check if the value entered is Alpha.
I need to do the same for number and Special character. Please advise. Thanks

Thanks to All of you. The desired solution to verify complex password that enforces desired security policies. An example that I am using is the following:
IF NOT (regexp_like(sz_complex_pw,'[[:digit:]]') AND regexp_like(sz_complex_pw,'[[:alpha:]]') AND regexp_like(sz_complex_pw,'[[:punct:]]') AND regexp_like(sz_complex_pw,'[[:upper:]]'))
THEN
--dbms_output.put_line('Password is not complex...');
RAISE sz_err_pw_complex; -- Complex Password is not compliant
END IF;
DBMS_OUTPUT.PUT_LINE('Complex Password is in Compliance...');
EXCEPTION
This was helpful to me and I trust others will find helpful.
