=head1 NAME
DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server - Support for Microsoft
SQL Server via DBD::Sybase
=head1 SYNOPSIS
This subclass supports MSSQL server connections via L<DBD::Sybase>.
=head1 DESCRIPTION
This driver tries to determine whether your version of L<DBD::Sybase> and
supporting libraries (usually FreeTDS) support using placeholders, if not the
storage will be reblessed to
L<DBIx::Class::Storage::DBI::Sybase::Microsoft_SQL_Server::NoBindVars>.
The MSSQL specific functionality is provided by
L<DBIx::Class::Storage::DBI::MSSQL>.

if (not $self->_use_typeless_placeholders) {
carp_once <<'EOF' unless $ENV{DBIC_MSSQL_FREETDS_LOWVER_NOWARN};
Placeholders do not seem to be supported in your configuration of
DBD::Sybase/FreeTDS.
This means you are taking a large performance hit, as caching of prepared
statements is disabled.
Make sure to configure your server with "tds version" of 8.0 or 7.0 in
/etc/freetds/freetds.conf .
To turn off this warning, set the DBIC_MSSQL_FREETDS_LOWVER_NOWARN environment
variable.

=head2 connect_call_datetime_setup
Used as:
on_connect_call => 'datetime_setup'
In L<connect_info|DBIx::Class::Storage::DBI/connect_info> to set:
$dbh->syb_date_fmt('ISO_strict'); # output fmt: 2004-08-21T14:36:48.080Z
On connection for use with L<DBIx::Class::InflateColumn::DateTime>
This works for both C<DATETIME> and C<SMALLDATETIME> columns, although
C<SMALLDATETIME> columns only have minute precision.
