Hi sireeshamanchala,

You can give some parameters to a RUNQRY, but only the one you see on the RUNQRY command, but I think you like to give selection parameters.
No, that is not possible, but you can solve that as follow.

----------- Sample CL --------------
OPNQRYF    FILE((mylib/myfile)) QRYSLT('myfield *eq' |> &MYPARM')
CPYFRMQRYF FROMOPNID(myfile) TOFILE(mytemp)
RUNQRY QRY(MYLIB/MYQRY)
----------- Sample CL ------------

I'm sure there is an other way like using SQL (enentually imbedded in RPG)
but this is the easyest to manage.

Regards,

Murphey

Hi
The way Murphy has given is the easiest but if it is not what you want the only other way is to use Query Management Queries.
You can write the query then split it down into extraction and prints and pass it parms
use
GO CMDQM
to have a look

Hi sireeshamanchala,

myfield is one of the fields from the file you like to QRY
if this is an item file it can look like this:

OPNQRYF    FILE((mylib/ITEMFIEL)) QRYSLT('ITNBR *gt' |> &MYPARM1 *AND ITEMNBR *lt' |> &MYPARM2 *AND ITACTIV *EQ "Y" ')

will select all active items between parm1 and parm2.

:-)

have fun

1. Create a file that will "hold" your parameters values
2. Create the query reading the parameter file and selecting from the "real" data files.
3. You can aso prompt the user to fill in the parameter file before running the query.

Good Luck

Ummm... you can pass parms into queries -- either Query/400 *QRYDFNs or Query Manager *QMQRYs -- by properly defining the queries in the beginning and then running them correctly. Overall, QM queries are superior and also easier to pass parms into.

To pass parms into a *QRYDFN, create what's called a "dependent query". Use any dummy name when prompted for the dependent file for the dependent column value since you won't actually use an additional file anyway. To run, use the STRQMQRY command specifying ALWQRYDFN(*YES) and supplying the *QRYDFN name for the QMQRY() parm. Whatever you typed for the dependent column name will be prompted back to you for a value. You can instead supply this via the SETVAR() parm to avoid prompting, thereby "passing in a parm to Query/400".

To pass parms into QM queries, use standard substitution variables in the QM query SQL statement. The substitution variable names will be prompted for just as above when you run the QM query with STRQMQRY. Again, SETVAR() can be used to avoid prompting.
