=head1 NAME

DBIx::Class::Storage::DBI::MSSQL - Storage::DBI subclass for MSSQL

=head1 SYNOPSIS

This subclass supports MSSQL, and can in theory be used directly
via the C<storage_type> mechanism:

  $schema->storage_type('::DBI::MSSQL');
  $schema->connect_info('dbi:....', ...);

However, as there is no L<DBD::MSSQL>, you will probably want to use
one of the other DBD-specific MSSQL classes, such as
L<DBIx::Class::Storage::DBI::Sybase::MSSQL>.  These classes will
merge this class with a DBD-specific class to obtain fully
correct behavior for your scenario.

=head1 METHODS

=head2 last_insert_id

=head2 sqlt_type

=head2 build_datetime_parser

The resulting parser handles the MSSQL C<DATETIME> type, but is almost
certainly not sufficient for the other MSSQL 2008 date/time types.
