DBIx::Class::Storage::DBI::MultiColumnIn(3)ontributed Perl Documentationlass::Storage::DBI::MultiColumnIn(3)



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()"
