 =head1 DESCRIPTION
 
-This class implements support specific to Microsoft SQL Server over ODBC,
-including auto-increment primary keys and SQL::Abstract::Limit dialect.  It
-is loaded automatically by by DBIx::Class::Storage::DBI::ODBC when it
-detects a MSSQL back-end.
-
-=head1 IMPLEMENTATION NOTES
-
-Microsoft SQL Server supports three methods of retrieving the IDENTITY
-value for inserted row: IDENT_CURRENT, @@IDENTITY, and SCOPE_IDENTITY().
-SCOPE_IDENTITY is used here because it is the safest.  However, it must
-be called is the same execute statement, not just the same connection.
+This class implements support specific to Microsoft SQL Server over ODBC.  It is
+loaded automatically by by DBIx::Class::Storage::DBI::ODBC when it detects a
+MSSQL back-end.
 
-So, this implementation appends a SELECT SCOPE_IDENTITY() statement
-onto each INSERT to accommodate that requirement.
+Most of the functionality is provided from the superclass
+L<DBIx::Class::Storage::DBI::MSSQL>.
