+=head1 CAVEATS
-=head1 BUGS
+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)
+into the SQL query itself, without using bind placeholders.
-Currently, this doesn't work right unless you call C<Class::C3::reinitialize()>
-after connecting.
+More importantly this means that caching of prepared statements is explicitly
+disabled, as the interpolation renders it useless.
-=head1 AUTHORS
+The actual driver code for MSSQL is in
+L<DBIx::Class::Storage::DBI::ODBC::Microsoft_SQL_Server>.
