Re: Quick join-logical question

That manual is still to be found in every release of IBM i - I found it at 7.3 and just posted what looks like the technique Patrik mentioned. I googled for "ibm db2 for i database programming" and found the manual there, in a Bulgarian version of Knowledge Center - the manual is still in English. But you can also get there using any version of Knowledge Center.

Hello Patrik

Couldn't find this "DB2 for AS/400 Database Programming", SC41-5701

Can you post a link to it?

TIA

Hello James,

It's been a while since I've set up a DB2 join-logical.

Suppose in my master file, I have two fields that refer to an employee

roster file: "Tech. Advisor" and "Tech. Supervisor."

I'm guessing there's a way to join the master file to the employee

roster file twice, but I don't know that for sure, and neither do I recall
exactly how.

Wasn't a similar question popping up just recently? Maybe even from me?

Yes, but there hasn't been a definitive answer.

I'll have time to RTFM tomorrow.

I think I found the answer in the classic "DB2 for AS/400 Database
Programming", SC41-5701, chapter about logical files. One of the missing
documentation gems I discovered just a couple of Months ago. This
extensively describes how to handle PFs and LFs and their associated
capabilities.

I take it that nothing substantial has changed since then ? in the last
two decades ? because it's all about classic files and not about SQL.

Highly recommended reading as a refresh, maybe? ;-)

:wq! PoC
