I opened an incident on this issue 4/99 and learned that it's behaving as designed. The source of the trouble is that correlated subqueries need to be able reference names from the surrounding query. The ANSI standard apparently does not require that such names be fully qualified, so NCR has not required it either. If you fully qualify your names, or put aliases on all your tables & use them to reference columns you will get the expected error message. For example:
> select * from mbtemp1 > where > c1 not in (select mbtemp2.c1 from mbtemp2) -or- > select * from mbtemp1 a > where a.c1 not in (select b.c1 from mbtemp2 b)
For reference: REC9BKD4G. The incident also references RFC DR42470, but I'm not sure why (I can't see DRs through support link).
Hope this helps.
