So you added a CASE clause that adds a new column based on t1.OhComp, and added that new column to the ORDER BY. What happens if you add t1.OhComp directly?

Subject: SQL Internal Error
Hi All,
I'm getting an SQL System Error from one of my subprocedures and it looks like an embedded SQL bug to me.
To be precise, the code is running and returning SqlCode -901, SqlState
58004 and producing a couple of spooled files:
DBOPTRC198, QSQSVCDMP, QDSPJOB
The text retreived from:
Get Diagnostics Condition 1 :ErrorMsg = MESSAGE_TEXT is returning "SQL System Error".
I would appreciate it if anyone could have a quick look at the SQL and my problem description and double check I'm not being a buffoon (in this matter at least...) Below are links to two versions of the SQL - one which works and one which fails and the only difference is an extra field in the main select and final group by.
My best understanding of what is causing the internal error is that the GROUP BY clause only contains host variables, plus a field on the main WHERE clause which also refers to a host variable.
When I run the code in Squirrel SQL client (which prompts for host variables it sees in the SQL) it runs fine - so it would seem to be an issue with the embedded SQL.
This code works fine:
https://code.midrange.com/8ed534b6cc.html
But this code fails as described above:
https://code.midrange.com/8c22090c16.html
And the only difference between the two of them is that I dropped a field which was not required from the main SELECT and the final GROUP BY:
From the working version:
Line 7 is dropped (it builds a field called ShipComplete from t1.OhComp) Line 57 - r.ShipComplete is removed from the GROUP BY.
So that leaves in the GROUP BY:
1. r.OhOrdr which is part of the primary Where clause, and based on a Host Variable (hence constant for the data set) 2. r.NumLines which is a Host Variable and therefore constant for the data set.
As I mentioned above, cutting and pasting the exact code from the program source to run in Squirrel SQL client, ran successfully.
Thanks to any/all who might have time for a quick look at this.
best regards,
