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()"
