RE: Passing parameters to a query

["Dan Bale" <dbale@xxxxxxxxxxx>]

A "regular" query, one created/modified using WRKQRY, is unable to accept
parameters.

If you convert such a query into a QM query, you can setup variables into the
query source and pass parameters to them from a HLL pgm.  However, IMHO, this is
a really UGLY thing!  It is not something I would want to give to a user.  I
have used it, reluctantly, and they are hard to debug, and some features of
regular queries are lost in the conversion.

Christopher's suggestion of using OPNQRYF is good as long as you realize that
you have to use CPYFRMQRYF after the OPNQRYF to get the data into a physical
data file; big files could eat up a lot of resources.  If this is the case, I'd
just as soon scrap the query and write an RPG program to process the OPNQRYF'd
data.

>>I never could figure that out.  I use opnqryf to select data and build in
qtemp.  Then run query over qtemp to format & print report.  No selection
are then coded in the query.

Hi there !

How can you pass parameters to a query?

Thanks.
