108 DBIx::Class::Storage::DBI::Sybase - Storage::DBI subclass for Sybase
112 This subclass supports L<DBD::Sybase> for real Sybase databases. If you are
113 using an MSSQL database via L<DBD::Sybase>, your storage will be reblessed to
114 L<DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server>.
118 If your version of Sybase does not support placeholders, then your storage
119 will be reblessed to L<DBIx::Class::Storage::DBI::Sybase::NoBindVars>. You can
120 also enable that driver explicitly, see the documentation for more details.
122 With this driver there is unfortunately no way to get the C<last_insert_id>
123 without doing a C<select max(col)>.
125 But your queries will be cached.
129 On connection C<syb_date_fmt> is set to C<ISO_strict>, e.g.:
130 C<2004-08-21T14:36:48.080Z> and C<dateformat> is set to C<mdy>, e.g.:
131 C<08/13/1979 18:08:55.080>.
133 This works for both C<DATETIME> and C<SMALLDATETIME> columns, although
134 C<SMALLDATETIME> columns only have minute precision.
136 You will need the L<DateTime::Format::Sybase> module if you are going to use
137 L<DBIx::Class::InflateColumn::DateTime>.
141 See L<DBIx::Class/CONTRIBUTORS>.
145 You may distribute this code under the same terms as Perl itself.
