Hi Thorsten,
> this is an SAP Open SQL issue and not related to the SAP MaxDB database
You are absolutely correct. I'm unsure if I really opened this thread 11 years ago under MaxDB or if this was a side effect of the migration a few years ago. Anyhow, it was discussed always correctly as an OpenSQL matter.
With this having said, the MaxDB hints you gave are interesting, but not relevant as long as one uses OpenSQL. But as said in my last answer in the last paragraph - from my point of view this should be avoided if possible (in general i.e.: if not developing a product which has to be able to run on all SAP supported DBs). Just yesterday I met someone which quite the same experience.
As soon as one can leave the OpenSQL path and has the situation to work on MaxDB (which I really really like, just the opposite with OpenSQL, which I really really dislike), your hints become very relevant again, and I didn't know these details so far. So, in any case, thanks for this!
Best regards
Detlev
