Re: SQL in CL.

Birgitta,
Thanks a bunch for the reply. I was looking for exactly something like
that...But I am stuck a little bit though. The following command fails...

CRTQMQRY QMQRY(TESTING/MYQMQRY) SRCFILE(TESTING/QQMQRYSRC)

This is the step where I intend to create a file called MYQMQRY and place my
SQL statement in it. I do not know if there is any care to be taken about
the positioning of the statement but I was just going to put the following
in the file...

'SELECT CSTNUM, CSNAME FROM TESTING.CSTMST WHERE CSTNUM = &PFLD1'

My CLLE program would look like this..

             PGM        PARM(&PARFLD1)

             DCL        VAR(&PARFLD1) TYPE(*CHAR) LEN(10)
             DCL        VAR(&QRYFLD1) TYPE(*CHAR) LEN(10)

             ChgVar     Var(&QRYFLD1) Value('''' *cat &PARFLD1 *Cat '''')

             STRQMQRY   QmQry(TESTING/MYQMQRY) Output(*PRINT) QmForm(*QMQRY)
AlwQryDfn(*No) +
                          SetVar((PFLD1   &QRYFLD1))
             ENDPGM

Any help would be much appreciated...

Jake.
