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()"
