You need to close the cursor in your program before calling the stored
procedure again.

Stored Procedures return result set by defining a cursor and opening it (but
do not close it before the procedure ends ... otherwise nothing is
returned!).
That's the reason why you could not use a regular OPEN but have to use the
ASSOCIATE command (cursor is already open you only have to associate it with
the returned result set..

If the stored procedure would have coded correctly it would have tried to
first close the cursor (and handle the error if it was not opened).
... but it seems not to be.

So, it is up to you to close the cursor at the end of your
program/procedure.

Subject: Resuse SQL Result Set?

I'm calling a SQL stored procedure from SQLRPGLE. It works fine for the
first call, but subsequent calls do not. The first EXEC SQL CALL properly
returns SQLSTATE 0100C, but subsequent calls return 00000.

What do I need to do to make multiple calls?

TIA

EXEC SQL CALL SCHEMA.PROC(:lFunction, :lInputParm);
aEqual(AD_HOC_RESULT_SETS :SQLSTATE);
EXEC SQL
associate result set locator (:ProcRS)
with procedure SCHEMA.PROC;
EXEC SQL close ProcCSR;
EXEC SQL allocate CSR cursor for result set :ProcRS;
aEqual(SUCCESS_SQL :SQLSTATE);

EXEC SQL FETCH NEXT FROM CSR INTO :lProcDs;
