[DB-SIG] Question on odbc with cross apply and for xml...

I have come across similar problems with executing complicated SQL. One
solution could be to place this in a view, and as the sg.support_group_nameand
sg.company are in the select list these can be moved to the where clause of
the select of the view.

eg. select * from ctm_support_group_view where company = 'UNINA' and
support_group_name like 'UNI-NA%'

This isn't a python solution, and of course I don't know how dynamic you
want these selects to be and if you will need to create thse views on the
fly either, and maintaining these views creates more work for your DBAs ...
