127 DBIx::Class::Storage::DBI::Sybase - Storage::DBI subclass for Sybase
131 This subclass supports L<DBD::Sybase> for real Sybase databases. If you are
132 using an MSSQL database via L<DBD::Sybase>, your storage will be reblessed to
133 L<DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server>.
137 If your version of Sybase does not support placeholders, then your storage
138 will be reblessed to L<DBIx::Class::Storage::DBI::Sybase::NoBindVars>. You can
139 also enable that driver explicitly, see the documentation for more details.
141 With this driver there is unfortunately no way to get the C<last_insert_id>
142 without doing a C<select max(col)>.
144 But your queries will be cached.
148 See L</connect_call_datetime_setup> to setup date formats
149 for L<DBIx::Class::InflateColumn::DateTime>.
153 See L<DBIx::Class/CONTRIBUTORS>.
