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.
