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()"

NAME

       DBIx::Class::Storage::DBI::UniqueIdentifier - Storage component for RDBMSes supporting GUID types

DESCRIPTION

       This is a storage component for databases that support GUID types such as "uniqueidentifier", "uniqueidentifierstr" or "guid".

       GUIDs are generated automatically for PK columns with a supported data_type, as well as non-PK with auto_nextval set.

METHODS

   new_guid
       The composing class must set "new_guid" to the method used to generate a new GUID. It can also set it to "undef", in which case the user is
       required to set it, or a runtime error will be thrown. It can be:

       string
	   In which case it is used as the name of database function to create a new GUID,

       coderef
	   In which case the coderef should return a string GUID, using Data::GUID, or whatever GUID generation method you prefer. It is passed
	   the $self DBIx::Class::Storage reference as a parameter.

       For example:

	 $schema->storage->new_guid(sub { Data::GUID->new->as_string });
