How about posting what you have tried so far ?

In the mean time check for the syntax for execute immediate in the following link

http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14261/executeimmediate_statement.htm#LNPLS01317

The below code is copied from the link you given:

In addition, if you need to call a procedure whose name is unknown until runtime, you can pass a parameter identifying the procedure. For example, the following procedure can call another procedure (drop_table) by specifying the procedure name when executed.

CREATE PROCEDURE run_proc (proc_name IN VARCHAR2, table_name IN VARCHAR2) AS BEGIN
EXECUTE IMMEDIATE 'CALL "' || proc_name || '" ( :proc_name )' using table_name;
END;
/


I also to call a dynamic procedure.

I need to call a procedure with 5 IN & 1 OUT & 2 IN OUT Parameters.

How to call the dynamic procedure?

It is hardly ever necessary to use dynamic sql, let alone dynamically call a stored procedure.
Why don't you show us your logic; there might be other (read:better) ways.

This implementation is a GREAT way to create a inefficient & non-scalable application.

begin
test_send('test_receive');
end;

when i execute the above begin-end, the following error is thrown:


Error starting at line 2 in command:
begin
test_send('test_receive');
end;
Error report:
ORA-01006: bind variable does not exist

ORA-06512: at line 2
01006. 00000 - "bind variable does not exist"
*Cause:

Kindly let us know the cause for this problem.

AND ALSO LET ME SUGGEST - HOW TO USE EXECUTE IMMEDIATE WITH EXAMPLE.

You could do the same thing yourself.

Thanks Michel.

Your Query helped me a lot.

BUT, WHEN WE ACCESS IN IN PROCEDURE, THE FOLLOWING ERROR IS THROWN.

LET ME HELP TO SOLVE THIS ISSUE.


Error starting at line 1 in command:
begin
test_send('TEST_RECEIVE');
end;
Error report:
ORA-06576: not a valid function or procedure name
ORA-06512: at "TST.TEST_SEND", line 5
ORA-06512: at line 2
06576. 00000 - "not a valid function or procedure name"
*Cause: Could not find a function (if an INTO clause was present) or
a procedure (if the statement did not have an INTO clause) to
call.
*Action: Change the statement to invoke a function or procedure



Thanks and Regards

cgmsuresh,
When you find yourself in a hole the first thing you should do is STOP DIGGING!

Please humor me & explain what problem you are really trying to solve at the 10000 foot level.

IMO, there is NEVER any reason to use EXECUTE IMMEDIATE to invoke PL/SQL procedures.

I got the same thing with your code, I analyzed it, understood why, and fixed the call. All is in my post.
Do the same thing.

But BEFORE follow Ana's advice and post the real problem you're trying to solve with this function.

Michel

Hi

My problem is:

I need to call a dynamic procedure with IN/OUT Parameters.

As Michel said, i can call the test_send in SQL> prompt.

But, if i try to call the test_send procedure in anonymous block, i got an error.

I can't find the fix provided by michel in his post.

Kindly let me know that post.

Thanks and Regards,

SURESH

And what did you do to try to find the origin of your error?
Copy and paste the whole session from start to error just like I did AND FORMAT IT.
