There's CPYFRMQRYF. I haven't looked to see if OPNQRYF generates a message if the selection is zilch.
I no longer use OPNQRYF. I've created a command that executes an SQL statement with REXX. If my selection is empty then I'll get back (should) the message SQL0100.
Eg :
CHGVAR VAR(&WSEL) VALUE( '+
INSERT INTO MYFILE +
SELECT * FROM MYOTHERFILE +
WHERE MYZONE = ' *CAT &MYCLVAR *CAT ' AND +
MYOTHERZONE = ''N'' +
ORDER BY KEYZONE DESC +
FETCH FIRST ROW ONLY')
* . This does a STRREXPRC that runs the SQL. */
STRREXPRC &WSEL
* .Traitement erreur. SQL0100 = no record found. */
MONMSG MSGID(SQL0000) EXEC(DO)
RCVMSG MSGTYPE(*EXCP) MSGID(&MSGID)
IF ( &MSGID *EQ 'SQL0100' ) RTNSUBR RTNVAL(0)
ELSE RTNSUBR RTNVAL(-1)
ENDDO
Here's the REXX code :
PARSE ARG iSql
RC=0
ADDRESS EXECSQL,
EXECSQL 'SET OPTION COMMIT = *NONE'
ADDRESS EXECSQL,
EXECSQL iSql
IF RC <> 0 THEN DO
MSGID = "SQL"RIGHT(STRIP(ABS(SQLCODE)),4,'0')
'SNDPGMMSG MSGID(&MSGID) MSGF(QSQLMSG) MSGDTA(&SQLERRMC) MSGTYPE(*ESCAPE)
END

Objet : OPNQRYF question.
Can anyone tell me if you can use an OPNQRYF statement in conjunction with a RTVMBRD command to see if the selection has actually selected anything ? I know there are other ways to do this in terms of RPG but I would like to keep this all within the CL processing if possible.
Thanks Stevie
