 -This storage driver uses L<DBIx::Class::Storage::DBI::NoBindVars> as a base.
 -This means that bind variables will be interpolated (properly quoted of course)
++If your version of Sybase does not support placeholders, then this storage
++driver uses L<DBIx::Class::Storage::DBI::NoBindVars> as a base,
++
++In which case, bind variables will be interpolated (properly quoted of course)
+ into the SQL query itself, without using bind placeholders.
+ 
+ More importantly this means that caching of prepared statements is explicitly
+ disabled, as the interpolation renders it useless.
+ 
++If your version of Sybase B<DOES> support placeholders (check
++C<<$dbh->{syb_dynamic_supported}>> then unfortunately there's no way to get the
++C<last_insert_id> without doing a C<select max(col)>.
++
++But your queries will be cached.
++
++=head1 DATES
++
++On connection C<syb_date_fmt> is set to C<ISO_strict>, e.g.:
++C<2004-08-21T14:36:48.080Z> and C<dateformat> is set to C<mdy>, e.g.:
++C<08/13/1979>.
++
++You will need the L<DateTime::Format::Strptime> module if you are going to use
++L<DBIx::Class::InflateColumn::DateTime>.
