RE: Load CL variables from SQL example

While CL & SQL are not a match made in heaven, I've used the DCLF/RCVF technique in the past.

If you need multiple selects & files concurrently, keep in mind that CL will support up to 5 DCLF's.

If you're talking about a single record result, consider using a command calling an RPG to do the work. I write a lot of "RTV" type commands to return configuration info to my CL programs.

Jack,

I will have multiple SQL with selects from multiple PF.

I don’t think I can join them, don’t have a common key.

You can select into a file MYLIB/MYRESULTS and then RCVF. Let's say your target db file has two columns, STRINGA and STRINGB.

DCLF MYLIB/MYRESULTS
RCVF /* Get one row */
SNDMSG MSG(&STRINGA) TOUSR(*REQUESTER)
SNDMSG MSG(&STRINGB) TOUSR(*REQUESTER)

If you have lots of rows, you can do it in a loop. Each RCVF instances (repetitiously the same) vars named after the columns.

Anyone have any examples.
