10 | DBIx::Class::Storage::DBI::NoBindVars - Sometime DBDs have poor to no support for bind variables |
11 | |
12 | =head1 DESCRIPTION |
13 | |
14 | This class allows queries to work when the DBD or underlying library does not |
15 | support the usual C<?> placeholders, or at least doesn't support them very |
16 | well, as is the case with L<DBD::Sybase> |
17 | |

21 | |
b33697ef |
22 | We can't cache very effectively without bind variables, so force the C<disable_sth_caching> setting to be turned on when the connect info is set. |
