-DBIx::Class::Storage::DBI::AmbiguousGlob - Storage component for RDBMS supporting multicolumn in clauses
-
-=head1 DESCRIPTION
-
-Some servers choke on things like:
-
-  COUNT(*) FROM (SELECT tab1.col, tab2.col FROM tab1 JOIN tab2 ... )
-
-claiming that col is a duplicate column (it loses the table specifiers by
-the time it gets to the *). Thus for any subquery count we select only the
-primary keys of the main table in the inner query. This hopefully still
-hits the indexes and keeps the server happy.
-
-At this point the only overriden method is C<_grouped_count_select()>
