=head1 NAME
-DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server - Storage::DBI subclass for MSSQL via
-DBD::Sybase
+DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server - Support for Microsoft
+SQL Server via DBD::Sybase
=head1 SYNOPSIS
-This subclass supports MSSQL connected via L<DBD::Sybase>.
+This subclass supports MSSQL server connections via L<DBD::Sybase>.
- $schema->storage_type('::DBI::Sybase::Microsoft_SQL_Server');
- $schema->connect_info('dbi:Sybase:....', ...);
+=head1 DESCRIPTION
-=head1 BUGS
+This driver tries to determine whether your version of L<DBD::Sybase> and
+supporting libraries (usually FreeTDS) support using placeholders, if not the
+storage will be reblessed to
+L<DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server::NoBindVars>.
-Currently, this doesn't work right unless you call C<Class::C3::reinitialize()>
-after connecting.
+The MSSQL specific functionality is provided by
+L<DBIx::Class::Storage::DBI::MSSQL>.
