Dear friends

I believe that the syntax diagram for the SELECT statement in the manuals
has an error in it:
In most flavours of SQL the subquery is part of the 'where' clause, not
part of the 'from' clause. The ADSM manual does give some examples with the
subquery in the 'where' clause.

IBM/Tivoli: please confirm (and if the syntax diagram is correct, can you
please give a few examples with the subquery in the 'from' clause). Thanks.

The manual also states (correctly as far as I can see) that subqueries ARE
supported (NOT supported in ADSM are: union, intersect, except and
correlated subqueries).

Regards
     Geetam


PS. Is anyone doing anything about the digests being screwed up? They are
becoming unreadable.
