143 | DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server - Support for Microsoft |
144 | SQL Server via DBD::Sybase |
98464041 |
145 | |
146 | =head1 SYNOPSIS |
147 | |
5608593e |
148 | This subclass supports MSSQL server connections via L<DBD::Sybase>. |

150 | =head1 DESCRIPTION |
d4483998 |
151 | |
7379eb67 |
152 | This driver tries to determine whether your version of L<DBD::Sybase> and |
153 | supporting libraries (usually FreeTDS) support using placeholders, if not the |
154 | storage will be reblessed to |
155 | L<DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server::NoBindVars>. |
98464041 |
156 | |
7379eb67 |
157 | The MSSQL specific functionality is provided by |
158 | L<DBIx::Class::Storage::DBI::MSSQL>. |
