Re: An embedded SQL generated EVAL that does not evaluate???

In case anybody wondered about how this issue was resolved...

I never was able to figure out what caused the actual issue, so I finally went back and started over. The change was a conversion from program-driven looping, through one of three different files, and it was taking about a full 60 seconds plus or minus 10 or 15 to get from the time they entered the menu option to get to the initial subfile view.  So I needed the performance of getting multi-row fetches.

I rewrote the changes "from scratch" again. This time I did not hit those blockers. It's still a mystery.

Sometimes I think about using SQL-CLI instead. I understand there's somewhat of a performance hit that way. In fact, I'm going to ask about that in a separate thread.

A likely scenario is you are now receiving an SQL Error because the fields you selected do not exactly match the definition you are attempting to fetch into.

I thought so too, but I checked the select list of fields and the fields in the DS fetched into, and they match exactly.

You have mentioned the SQLERR3 is zero, but what is SQLCODE or SQLSTATE.
Or in debug just "EVAL SQLCA" and get them all.

==> The SQLCODE is 100. However, when I run the SQL statement copied to an interactive SQL session, I get a great many records.

What I am doing right now is scratching what I have and I'm going to go step by step. I've compiled with one cursor and doing a single-row fetch. If it works I'll make it a multi-row fetch.
