=head1 NAME
-DBIx::Class::Storage::DBI::SQLAnywhere - Driver for Sybase SQL Anywhere
+DBIx::Class::Storage::DBI::SQLAnywhere - Driver for SQL Anywhere
=head1 DESCRIPTION
-This class implements autoincrements for Sybase SQL Anywhere and provides
-L<DBIx::Class::InflateColumn::DateTime> support.
+This class implements autoincrements for SQL Anywhere and provides
+L<DBIx::Class::InflateColumn::DateTime> support and support for the
+C<uniqueidentifier> type (via
+L<DBIx::Class::Storage::DBI::SQLAnywhere::Cursor>.)
You need the C<DBD::SQLAnywhere> driver that comes with the SQL Anywhere
distribution, B<NOT> the one on CPAN. It is usually under a path such as:
sub last_insert_id { shift->_identity }
-sub _new_uuid { 'UUIDTOSTR(NEWID())' }
-
-sub insert {

+ my ($identity_col) =
+ grep { $colinfo->{$_}{is_auto_increment} } keys %$colinfo;
# user might have an identity PK without is_auto_increment
+#
+# FIXME we probably should not have supported the above, see what
+# does it take to move away from it
