Calling a PL/SQL function returning Netsed Table Rows

Hi,
I am trying to call a Function which returns Nested Table rows (as Out Parameter) in Java .
When I am trying to use
pstmt.registerOutParameter(3, OracleTypes.OTHER);
to capture the Out parameter in Java code , I get the follwoing error :
java.sql.SQLException: Invalid column type
I have even tried using OracleTypes.JAVA_OBJECT ,but I get the same error.
If I use OracleTypes.JAVA_STRUCT I get
java.sql.SQLException: Parameter Type Conflict: sqlType=2008
error.
Please help .
Am I doing the right thing ?
Thanks in advance.

Report- Pl/sql function returning sql query parsing page items as text?

Hi Team,
I am facing a strange issue .
I have four page items namely
1)JOB_CODE
2)MIN_EXP
3) MAX_EXP
4) SOURCES1
I have a report of the type "Pl/sql function returning sql query"
declare
v_sql varchar2(4000);
begin
if (:JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql:= 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:JOB_CODE IS NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MIN_EXP IS NULL and :JOB_CODE IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years <= :MAX_EXP and V_REQUIREMENT = :JOB_CODE and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MAX_EXP is null and :JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
end if;
insert into query_list values (v_sql);
insert into debug values (:JOB_CODE , :MIN_EXP , :MAX_EXP , :SOURCES1);
return v_sql;
end;
Please not that I am insertin the query into a table called Query_list and the page item values into the table called Debug thru the pl/sql function which returns teh query.
Now I select the data from the debug tables.
select unique(query) from query_list;
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like '%:SOURCES1%'
select * from debug;
JOBCODE     MINEX     MAXEX     SOURCE
21     1     10     donkeyHire
And if I run the query in sql I get some records returned
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = 21 and v_experience_years >= 1 and v_experience_years <= and source like 'donkeyHire'
V_CANDIDATE_ID     V_FNAME     V_CURRENT_EMPLOYER     V_EXPERIENCE_YEARS
2     Vengu     Andale Tech     4
But the record does not show up in the report!
does this type of report parse page items as text?
Why is it so?
Waiting for an early reply.
Thanks,
venkat

Venkat - You don't want to put ':SOURCES1' in quotes like that.

SQL report region source to call a pl/sql function using DB link

Hi - I have a pl/sql function fn_dbtype(id NUMBER) defined in database X. The pl/sql function executes couple DML statements and returns a string (a SELECT query). I am able to call this function using SQL Plus (Connected to Database X) as below and it works fine:
declare
vSQL VARCHAR2(100);
begin
vSQL := fn_dbtype(1);
end;
The DML operations completed fine and vSQL contains the "Select" query now.
In APEX:
I am trying to create a SQL report in APEX using SQL query(PL/SQL function returning a sql statement) option. I am trying to figure out what to put in the region source so that the output of the "Select" query is displayed in the report.
Moreover APEX is hosted in a different database instance. So I would need to call this pl/sql function using a DB Link.
Please let me know what I need to put in the region source to execute the pl/sql function which returns the "Select" query thereby displaying the query output in the report. Thanks.

Issue with running PL/SQL function returning Sql query

hi, I am trying to create a report region by using the option of PL/SQL function returning sql query.
I notice that it's very slow for the report region page to show up. In my PL/SQL function body, there are only 3 steps, first update all the 10 rows of varchar2 fields to null,then insert values to those fields, then select all from the table to show report results. It takes more than 5 minitues for the page to load up, how ever, if i run those steps in SQL*Plus, it only takes a couple of seconds to finish. Any suggestions?
Thanks,
gina

Sergio, the codes are as followed,
Declare
q varchar2(32767); -- query
Begin
q := 'select "ID",'||
'"ENTRY NAME","TOTAL","#CM","%CM","#CA",'||
'"%CA", from Info_table';
update info_table
set "TOTAL" = '',
"#CM" = '',
"%CM" = '',
"#CA" ='',
"%CA"=''
where "ID"<=10;
// set all data in column Total to null,there is only 10 rows in the table
update info_Table set Total = vTotal,
"#CM" = vCM
(those variables hold user key-in Text filed value)
where ID = 1;
return q;
End;

On Submit process not firing -report (PL/SQL function returning SQL query)

Can anyone suggest possible causes / solutions for the following problem?
I have a report region that uses a PL/SQL function returning SQL query. The report allows the user to update multiple fields / rows and then click a button to submit the page which should run the On-Submit process to update the database. However the process does not run and I get a 'HTTP404 page cannot be found' error; and when I navigate back using the Back button I cannot then navigate to any other page in my application without getting the same error. The button was created by a wizard selecting the options to submit the page and redirect to a (same) page. The button does not actually have a redirect in its definition but the wizard created a branch to the same page which should work and the button has the text 'submit as SUBMIT' next to it so it appears to be set up correctly.
I have recreated this page several times in my application and I cannot get the On-Submit process to run. However I have created a cut down version of the same page in the sample application on apex.oracle.com at http://apex.oracle.com/pls/otn/f?p=4550:1:179951678764332 and this works perfectly so I am at a loss to understand why it does not work in my application. I cannot post any part of the application itself but if anybody would like to check out page 30 of the sample application (Customer Update Test tab) updating the surnames only, using credentials ja, demo, demo this is pretty much what I have got in my application.
Any ideas would be much appreciated?

Thanks for the suggestions guys. I have now identified that the problem goes away when I remove the second table from my report query. The original report query retrieved data from two tables and the process was updating only one of the tables. I thought I had approached the task logically i.e. first get the report to display the records from the two tables, then get the process to update the first table and finally to modify the process further to update the second table.
Can anyone point me to an example of multiple row updates on multiple tables using a PL/SQL function returning an SQL query?

Column order in SQL Query (PL/SQL function returning a query)

Hi,
when I define a PL/SQL function returning a query inside a region, I often find that the column order is arbitrarily changed.
How do I enforce the column order ?

I removed the 11th column called service_name from this dynamic query: and now the report says: report error:

Need to obtain updateable ResultSet via call to PL/SQL function

I'm using JDBC and the Oracle JDBC driver to call a PL/SQL function that returns a SYS_REFCURSOR. I do this via a CallableStatement object and then cast the output parameter to a ResultSet object. However, I want this ResultSet object I end up with to be updateable. The following code throws an exception stating "Invalid operation for read only resultset: updateString ":
cstmt2 = con.prepareCall("{? = call get_upload_entry_for_update(?)}",
                         ResultSet.TYPE_FORWARD_ONLY,
                         ResultSet.CONCUR_UPDATABLE);
cstmt2.registerOutParameter(1, OracleTypes.CURSOR);
cstmt2.setInt(2, newUploadId);
cstmt2.execute();
rs = (ResultSet) cstmt2.getObject(1);
rs.next();
rs.updateString("UPLOAD_FILENAME", fileName);
// . . .So even though, I create the CallableStatement such that ResultSets should be updateable, it's not allowing me to do any updates. Also, in case you're wondering, inside the PL/SQL function, the query on which the cursor is based is a select statement which does specify "for update" at the end.
I can get it to work as follows using a Statement object that executes the SELECT statement directly instead of a CallableStatement that executes a PL/SQL function:
Statement stmt = con.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_UPDATABLE);
rs = stmt.executeQuery("select UPLOAD_FILENAME, UPLOAD_FILE from rf_upload where upload_id = "+newUploadId+" for update");
rs.next();
rs.updateString("UPLOAD_FILENAME", fileName);
//. . . Although this works, the project I'm working has a goal to encapsulate all SQL into Functions and Stored Procedures so I'd like to get it working that way instead.
So the bottom-line question is: Using the Oracle JDBC driver, how can I call a PL/SQL function in such a way that I can obtain an updateable ResultSet object?
Thanks for any suggestions. I'd be happy to clarify anything that's unclear.

Hmmm...
I'm still scratching my head about this one, just not sure it's doable, but I'll point out something, maybe it will give you a clue...
In your code, you have:
cstmt2 = con.prepareCall("{? = call get_upload_entry_for_update(?)}",
                         ResultSet.TYPE_FORWARD_ONLY,
                         ResultSet.CONCUR_UPDATABLE);I don't think the ResultSet parameters do anything towards your goal of getting an updatable result set via the returned cursor, those parameters affect the result set produced if you were to call:
ResultSet rs2 = cstmt2.executeQuery();and not the result set generated by:
rs = (ResultSet) cstmt2.getObject(1);Futhermore, while the "FOR UPDATE" is almost certainly something you want to do, it also doesn't affect the cursor (I think) but merely locks the affected rows in the DB.
You might try calling rs.getType() and rs.getConcurrency() on the ResultSet you get from getObject, though I suspect they'll merely confirm the bad news that the cursor your getting back isn't right...
You also might try the Oracle-specific getCursor call:
rs = ((OracleCallableStatement)cstmt2).getCursor (1)instead of getObject, though I don't think it will help...
I've been curious enough to dig around through most of my handy references and Oracle's docs and MetaLink and come up mostly empty, although almost 5 years ago Oracle Support said:
" Reference Cursors from a pl/sql stored procedure are not updateable in any language."

Calling a PL/SQL function from java

I would like to call a pl/sql function from java. My pl/sql function is taking arrays of records as parameters. How do i proceed? Which specific oracle packages do I have to import?
Please send an example.
TIA,
Darko Guberina

Documentation here: http://download-uk.oracle.com/docs/cd/B14117_01/java.101/b10983/datamap.htm#sthref185
says JPublisher can publish records too.
But when I change the example given at http://download-uk.oracle.com/docs/cd/B14117_01/java.101/b10983/datamap.htm#sthref190 as following:
PACKAGE "COMPANY" AS
type emp_rec is record (empno number, ename varchar2(10));
type emp_list is varray(5) of emp_rec;
type factory is record (
name varchar(10),
emps emp_list
function get_factory(p_name varchar) return factory;
END;
then I see <unknown type or type not found> at sql or java files generated. Any ideas?

Calling a pl/sql function.

Hi,
I couldn't manage to call a pl/sql function that takes some arguments or no arguments.
I couldn't find an example but searching through previous topics / discussions I could write something like this :
ExpressionBuilder expBuilder = new ExpressionBuilder();
Vector args = new Vector();
Vector parameters = new Vector();
// dynamically fill these vectors if there are any arguments to the function
Expression exp = expBuilder.getFunctionWithArguments(functionName, args);
DataReadQuery query = new DataReadQuery();
query.setSelectionCriteria(exp);
Iterator iter = args.iterator();
while (iter.hasNext())
query.addArgument((String)iter.next());
Object obj = getActiveUnitOfWork().executeQuery(query, parameters);
at the end what I get is NullPointerException, probably I'm missing something.
UnitOfWork(17384)--#executeQuery(DataReadQuery())

You must use SQL with DataReadQuery, you cannot use expressions. Since a single value is returned the ValueReadQuery can be used to filter the result.
Example:
ValueReadQuery query = new ValueReadQuery("Select My_func(#arg1, #arg2) from dual");
query.addArgument("arg1");
query.addArgument("arg2");
Vector arguments = new Vector(2);
arguments.add("1");
arguments.add("2");
Object result = session.executeQuery(query, arguments);
or,
Vector result = session.executeSelectingCall(new SQLCall("select my_func(1, 2) from dual"));

Ahmed,

scott,you efforts was useful and i beleive that the error that i am getting it is from the function that i have can you please take a look on :
FUNCTION CHECK_USER
( P_USERNAME IN varchar2,
P_PASSWORD IN varchar2)
RETURN boolean
IS
BEGIN
for c1 in (select user_name, password from vms2_employee_details where user_name = P_USERNAME)
loop
if P_PASSWORD = c1.password then
return true;
------dbms_output.put_line('the return from the function is true');
else
return false;
----dbms_output.put_line('the return from the function is false');
end if;
end loop;
EXCEPTION
WHEN no_data_found THEN
return false;
when others then
return false;
----dbms_output.put_line('the return from the function is false');
END;
and tell me what do you think ,
thanks,
ahmed

Call a pl/sql function froma jsp

I need to call an pl/sql function which basically returns true or false depending on the count. based on the return value I have to alert a message. how can i call the pl/sql fucntion in a jsp?
thanks for ur help.

You call the function the same way you would from anywhere, although i don't recommend you call database functions directly from a JSP page as it's bad form.

SQL Query(PL/SQL Function Returning SQL Query)

I am trying to write a dynamic report using SQL Query(PL/SQL Function Returning SQL Query).
I can get the report to run but I need to concatinate some columns into one, seperated by a comma or a dash.
I have tried select *****||','||***** alias
also select *****||'-'||***** alias
but I always get an error.
Is there a way of doing this please
Gus

This is my full query
declare
v_query varchar2(4000);
begin
if :P63_TRAN_INFO = 2 THEN
v_query := 'select
     A.FILENR,
     A.EXERCISENAME,
A.STARTDATE,
A.ENDDATE,
     A.UNIT,
A.ACCADDRESSES, B.ADDRESS, B.ADDRESS_1, B.POST_CODE, B.TOWN,
     A.EXERCISEAREAS,
     A.TOTALVEHICLES,
A.TOTALTROOPS+A.RNTOTALTROOPS+A.RAFTOTALTROOPS TOTALTROOPS,
A.CAR, A.MINIBUS, A.HGV,
A.NAMERANK, A.ADDRESS, A.ADDRESSI, A.ADDRESSII, A.POSTCODE,
A.TRANSIT,
A.INFOONLY
from     BFLOG_AT A, BFLOG_ACCADDRESS B
WHERE A.ACCADDRESSES = B.NAME
AND A.STARTDATE >= :P63_START_DATE
AND A.ENDDATE <= :P63_END_DATE
AND A.AUTHORISED = 1
AND A.INFOONLY = 1' ;
END IF;
RETURN v_query;
END;
This query runs ok, but if I try changing it to the code below with fields concatinated, then it fails
declare
v_query varchar2(4000);
begin
if :P63_TRAN_INFO = 2 THEN
v_query := 'select
     A.FILENR,
     A.EXERCISENAME,
A.STARTDATE,
A.ENDDATE,
     A.UNIT,
A.ACCADDRESSES||','||B.ADDRESS||','||B.ADDRESS_1||','||B.POST_CODE||','||B.TOWN ADDRESS,
     A.EXERCISEAREAS,
     A.TOTALVEHICLES,
A.TOTALTROOPS+A.RNTOTALTROOPS+A.RAFTOTALTROOPS TOTALTROOPS,
A.CAR, A.MINIBUS, A.HGV,
A.NAMERANK, A.ADDRESS, A.ADDRESSI, A.ADDRESSII, A.POSTCODE,
A.TRANSIT,
A.INFOONLY
from     BFLOG_AT A, BFLOG_ACCADDRESS B
WHERE A.ACCADDRESSES = B.NAME
AND A.STARTDATE >= :P63_START_DATE
AND A.ENDDATE <= :P63_END_DATE
--AND (A.EXERCISEAREAS LIKE "GAP, OA, OAL")
--OR (A.EXERCISEAREAS LIKE "Harz")
AND A.AUTHORISED = 1
AND A.INFOONLY = 1' ;
END IF;
RETURN v_query;
END;

PL/SQL function returning a SQL Query

Is this only availabe in HTML db or in 10g in general? Where do I find more about this feature?
Thanks in advance,
Denes

Not sure what you mean. HTML DB allows to use a PL/SQL function returning a valid SQL query in report regions.
Its just a PL/SQL function returning a string, outside of HTML DB, I guess you can use it wherever it makes sense.

HTTP - Calling a PL/SQL Function

I am wanting to call a PL/SQL Function over the web.
Say if I am using Oracle APEX and my user is the standard "HR".
How would I call a function from PL/SQL made by the user HR called EXAMPLE_FUNCTION.

It depends on where you want to call the function. Easiest method would be to create a region based on the PLSQL function.
If you want to do some plsql function after the page is rendered, then you should find out the event for the field such as onchange or onblurr and call
a Javascript. The javascript can cal the plsql function...
Also note that under the database forums there is a forum for Apex and u can see many samples
