# DBIx::Class::Storage::DBI::MultiColumnIn(3pm)

Storage component for RDBMS supporting multicolumn in clauses

## 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()"`
