NAME¶
DBIx::Class::Storage::DBI::MultiColumnIn - Storage component for RDBMS
supporting multicolumn in clauses
DESCRIPTION¶
While ANSI SQL does not define a multicolumn in operator, many databases can in
fact understand WHERE (cola, colb) IN ( SELECT subcol_a, subcol_b ... ) The
storage class for any such RDBMS should inherit from this class, in order to
dramatically speed up update/delete operations on joined multipk resultsets.
At this point the only overridden method is "_multipk_update_delete()"
