DBIx::Class::Storage::DBI::AmbiguousGlob - Storage component for RDBMS supporting multicolumn in clauses
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 _subq_count_select()
