.SH "NAME"
DBIx::Class::Storage::DBI::Sybase::ASE::NoBindVars \- Storage::DBI subclass for
Sybase ASE without placeholder support
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
If you're using this driver then your version of Sybase or the libraries you
use to connect to it do not support placeholders.
.PP
You can also enable this driver explicitly using:
.PP
.Vb 3
\&  my $schema = SchemaClass\->clone;
\&  $schema\->storage_type(\*(Aq::DBI::Sybase::ASE::NoBindVars\*(Aq);
\&  $schema\->connect($dsn, $user, $pass, \e%opts);
.Ve
.PP
See the discussion in
\&\*(L"Using ? Placeholders & bind parameters to \f(CW$sth\fR\->execute\*(R" in DBD::Sybase
for details on the pros and cons of using placeholders with this particular
driver.
.PP
One advantage of not using placeholders is that \f(CW\*(C`select @@identity\*(C'\fR will work
for obtaining the last insert id of an \f(CW\*(C`IDENTITY\*(C'\fR column, instead of having to
do \f(CW\*(C`select max(col)\*(C'\fR in a transaction as the base Sybase driver does.
.PP
When using this driver, bind variables will be interpolated (properly quoted of
course) into the \s-1SQL\s0 query itself, without using placeholders.
.PP
The caching of prepared statements is also explicitly disabled, as the
interpolation renders it useless.
