Re: Quick join-logical question

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? ;-)
