Question

I execute a stored proc as follows:

var myOutput varchar2

exec myproc(:myOutput)

print myOutput

However, this does not work.

I get an error message saying:

Bind Variable "myOutput" is NOT DECLARED

When I use a refcurser rather than a varchar2 in other procs, this works. What am I doing wrong?

Thanks!

So you have a procedure like this:

CREATE OR REPLACE PROCEDURE bark ( woof IN OUT VARCHAR2 )
IS
BEGIN
  woof := 'Woof!';
END bark;

Then you run:

SQL> var myOutput VARCHAR2(10) 
SQL> exec bark(:myOutput);

PL/SQL procedure successfully completed.

SQL> print myOutput

MYOUTPUT
--------------------------------
Woof!

Is this similiar to what you are trying to do?
