NAME
       DBIx::Class::Storage::DBI::Sybase::ASE::NoBindVars - Storage::DBI subclass for Sybase ASE without
       placeholder support

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.

       You can also enable this driver explicitly using:

         my $schema = SchemaClass->clone;
         $schema->storage_type('::DBI::Sybase::ASE::NoBindVars');
         $schema->connect($dsn, $user, $pass, \%opts);

       See the discussion in "Using ? Placeholders & bind parameters to $sth->execute" in DBD::Sybase for
       details on the pros and cons of using placeholders.

       One advantage of not using placeholders is that "select @@identity" will work for obtaining the last
       insert id of an "IDENTITY" column, instead of having to do "select max(col)" in a transaction as the
       base Sybase driver does.

       When using this driver, bind variables will be interpolated (properly quoted of course) into the SQL
       query itself, without using placeholders.

       The caching of prepared statements is also explicitly disabled, as the interpolation renders it
       useless.
