[Zope] database functions & zope

[Bob Tierney]

One of the requirements of a DA is to return information about the result
set columns.  Does Sybase give a name to column "count(*)".  Some database
products do and some don't.  Try giving the column an alias name like so

select count(*) as total from db_table

assuming Sybase supports this of course.

Regards,

Bob
