54 DBIx::Class::Storage::DBI::Sybase::NoBindVars - Storage::DBI subclass for Sybase
55 without placeholder support
59 If you're using this driver than your version of Sybase does not support
60 placeholders. You can check with:
62 $dbh->{syb_dynamic_supported}
64 You can also enable this driver explicitly using:
66 my $schema = SchemaClass->clone;
67 $schema->storage_type('::DBI::Sybase::NoBindVars');
68 $schema->connect($dsn, $user, $pass, \%opts);
70 See the discussion in L<< DBD::Sybase/Using ? Placeholders & bind parameters to
71 $sth->execute >> for details on the pros and cons of using placeholders.
73 One advantage of not using placeholders is that C<select @@identity> will work
74 for obtainging the last insert id of an C<IDENTITY> column, instead of having to
75 do C<select max(col)> as the base Sybase driver does.
77 When using this driver, bind variables will be interpolated (properly quoted of
78 course) into the SQL query itself, without using placeholders.
80 The caching of prepared statements is also explicitly disabled, as the
81 interpolation renders it useless.
85 See L<DBIx::Class/CONTRIBUTORS>.
