=head1 NAME

SQL::Translator::Producer::SQLServer - MS SQLServer producer for SQL::Translator

=head1 SYNOPSIS

  use SQL::Translator;

  my $t = SQL::Translator->new( parser => '...', producer => 'SQLServer' );
  $t->translate;

=head1 DESCRIPTION

B<WARNING>B This is still fairly early code, basically a hacked version of the
Sybase Producer (thanks Sam, Paul and Ken for doing the real work ;-)

=head1 Extra Attributes

=over 4

=item field.list

List of values for an enum field.

=back

=head1 TODO

 * !! Write some tests !!
 * Reserved words list needs updating to SQLServer.
 * Triggers, Procedures and Views DO NOT WORK
