-DBIx::Class::Storage::DBI::Sybase::ASA - Driver for Sybase SQL Anywhere
+DBIx::Class::Storage::DBI::SQLAnywhere - Driver for Sybase SQL Anywhere
=head1 DESCRIPTION
-This class implements autoincrements for Sybase SQL Anywhere and selects the
-RowNumberOver limit implementation.
+This class implements autoincrements for Sybase SQL Anywhere, selects the
+RowNumberOver limit implementation and provides
+L<DBIx::Class::InflateColumn::DateTime> support.
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:
- /opt/sqlanywhere11/sdk/perl
+ /opt/sqlanywhere11/sdk/perl
+
+Recommended L<DBIx::Class::Storage::DBI/connect_info> settings:
+
+ on_connect_call => 'datetime_setup'

+=head2 connect_call_datetime_setup
+
+Used as:
+
+ on_connect_call => 'datetime_setup'
+
+In L<DBIx::Class::Storage::DBI/connect_info> to set the date and timestamp
+formats (as temporary options for the session) for use with
+L<DBIx::Class::InflateColumn::DateTime>.
+
+The C<TIMESTAMP> data type supports up to 6 digits after the decimal point for
+second precision. The full precision is used.
+
+The C<DATE> data type supposedly stores hours and minutes too, according to the
+documentation, but I could not get that to work. It seems to only store the
+date.
+
+You will need the L<DateTime::Format::Strptime> module for inflation to work.
