77 DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server - Support for Microsoft
78 SQL Server via DBD::Sybase
82 This subclass supports MSSQL server connections via L<DBD::Sybase>.
86 This driver tries to determine whether your version of L<DBD::Sybase> and
87 supporting libraries (usually FreeTDS) support using placeholders, if not the
88 storage will be reblessed to
89 L<DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server::NoBindVars>.
91 The MSSQL specific functionality is provided by
92 L<DBIx::Class::Storage::DBI::MSSQL>.
96 See L<DBIx::Class/CONTRIBUTORS>.
