6=head1 NAME
7
8DBIx::Class::SQLMaker - An SQL::Abstract-based SQL maker class
9
10=head1 DESCRIPTION
11
12This module is a subclass of L<SQL::Abstract> and includes a number of
13DBIC-specific workarounds, not yet suitable for inclusion into the
14L<SQL::Abstract> core. It also provides all (and more than) the functionality
15of L<SQL::Abstract::Limit>, see L<DBIx::Class::SQLMaker::LimitDialects> for
16more info.
17
18Currently the enhancements to L<SQL::Abstract> are:
19
20=over
21
22=item * Support for C<JOIN> statements (via extended C<table/from> support)
23
24=item * Support of functions in C<SELECT> lists
25
26=item * C<GROUP BY>/C<HAVING> support (via extensions to the order_by parameter)
27
28=item * Support of C<...FOR UPDATE> type of select statement modifiers
29
30=back
31
32=cut
