79 | |
80 | This works for both C<DATETIME> and C<SMALLDATETIME> columns, although |

144 | =head1 NAME |
145 | |
146 | DBIx::Class::Storage::DBI::Sybase - Storage::DBI subclass for Sybase |
147 | |
148 | =head1 SYNOPSIS |
149 | |
7e8cecc1 |
150 | This subclass supports L<DBD::Sybase> for real Sybase databases. If you are |
151 | using an MSSQL database via L<DBD::Sybase>, your storage will be reblessed to |
152 | L<DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server>. |
3885cff6 |
153 | |
7e8cecc1 |
154 | =head1 DESCRIPTION |
d4483998 |
155 | |
7e8cecc1 |
156 | If your version of Sybase does not support placeholders, then your storage |
157 | will be reblessed to L<DBIx::Class::Storage::DBI::Sybase::NoBindVars>. You can |
158 | also enable that driver explicitly, see the documentation for more details. |
c5ce7cd6 |
159 | |
7e8cecc1 |
160 | With this driver there is unfortunately no way to get the C<last_insert_id> |
161 | without doing a C<select max(col)>. |
c5ce7cd6 |
162 | |
163 | But your queries will be cached. |
164 | |
165 | =head1 DATES |
166 | |
3abafb11 |
167 | See L</connect_call_datetime_setup> to setup date formats |
168 | for L<DBIx::Class::InflateColumn::DateTime>. |
c5ce7cd6 |
169 | |
63d46bb3 |
170 | =head1 IMAGE COLUMNS |
171 | |
172 | See L</connect_call_blob_setup> for a L<DBIx::Class::Storage::DBI/connect_info> |
173 | setting you need to work with C<IMAGE> columns. |
