I wrote a stored procedure in Oracle 11g. It has 4 input parameters and 60 output parameters. It executes successfully and returns output using GUI in Oracle SQL developer tool.
But problem is in SSRS I connect with Oracle as ODP.NET Data Source. Test connection succeeds in shared data set properties.
When I select the specific stored procedure and pass 4 input parameters which are VARCHAR2 Data types
it shows an error:
You have to use the output parameters as well when you call the procedure.
PS: I don't like the idea of having 60 output parameters. I'd use a record or a collection (or both).
I am new to IIB, trying to call SQL server stored procedure using ESQL. Could anyone share working example to call stored procedure which returns single value.
There are 2 ways you can call a stored procedure in ESQL:
Define a procedure with the external keyword
https://www-01.ibm.com/support/knowledgecenter/SSMKHH_9.0.0/com.ibm.etools.mft.doc/ac17040_.htm
Or use the PASSTHRU statement and call the stored procedure by putting the SQL command to call it into the parameter of the statement

I'm used to Microsoft SQL Server, where the last SELECT query of a stored procedure determines what is returned.
In Oracle, I'm always using a SYS_REFCURSOR OUT parameter to return data from queries.
Are there other options of returning data from SELECT queries in Oracle stored procedures?
How about SELECT queries that select only one row? Is a SYS_REFCURSOR still necessary?
EDIT: I need to know the answer for Oracle 11g R2 (should have mentioned that explicitly instead of just in the tags).
Until now Oracle has not supported the SQL Server style of procedures implicitly returning a result set, you have had to explicitly return something - which could be a SYS_REFCURSOR or a collection or whatever.
In Oracle 12C a new feature has been added called Implicit Statement Results, which is designed to emulate the SQL Server way of working. However, this is really intended to support migration of existing code from SQL Server; for fresh Oracle development you would be best advised to learn the way Oracle normally does things.
Oracle PL/SQL Procedures can return all the supported basic datattype( date,varchar2,number) plus complex ( records, tables, varray)
Another option is the pipelined function, in which you call the function as:
select ...
from table(my_function(param1 => 1, ...))
See docs for details.
Just for clarifying, ORACLE procedures cannot 'RETURN" per se, a SYS_REFCURSOR OUT parameter is more like changing the value of a variable reference inside the procedure.
Apart from SYS_REFCURSOR, if you are returning only one row of a table, say EMPLOYEE, you can also define a record as EMPLOYEE%ROWTYPE and use it as a OUT type.
Or like:
PROCEDURE pr_proc (v_input in number
v_emp_row out EMPLOYEE%ROWTYPE )

is it possible to execute a stored procedure inside a user defined function in Oracle 10g database?
If yes, could you please give en example?
Thanks.
Sure you can. See for example The last example in Oracle® Database SQL Reference
10g Release 1 (10.1) Create function
The example uses a package but can also be a stored procedure. No problems.
What is your problem?
I had to change the SQL stored procedure to ORacle stored procddure.I am able to successfully execute my modified stored procedure in oracle.
But unable to obtain the query result in CF for the Oracle stored-Procedure.I have used <cfquery>.
Any suggestions or tips to for using an Oracle stored proc/CF-8?
Think you need cfstoredproc, not cfquery.
See manual page for more details.
It does really depend on how it reacts, i'd test your stored proc in oracle sql+plus first, to make sure it returns data, then try it via cfquery or stored procedure...
