# Start of the allow_failures block
Revision history for DBIx::Class
+<unreleased DQ stuff, last was 0.08901-TRIAL>
+ * Start of experimental Data::Query-based release cycle
+ - Any and all newly introduced syntax features may very well change
+ or disappear altogether before the 0.09000 release
+
+<unreleased mainline>
* Fixes
- Fix on_connect_* not always firing in some cases - a race condition
existed between storage accessor setters and the determine_driver

+=head1 OPERATORS
+
+=head2 -ident
+
+Used to explicitly specify an SQL identifier. Takes a plain string as value
+which is then invariably treated as a column name (and is being properly
+quoted if quoting has been requested). Most useful for comparison of two
+columns:
+
+ my %where = (
+ priority => { '<', 2 },
+ requestor => { -ident => 'submitter' }
+ );
+
+which results in:
+
+ $stmt = 'WHERE "priority" < ? AND "requestor" = "submitter"';
+ @bind = ('2');
+
+=head2 -value
+
+The -value operator signals that the argument to the right is a raw bind value.
+It will be passed straight to DBI, without invoking any of the SQL::Abstract
+condition-parsing logic. This allows you to, for example, pass an array as a
+column value for databases that support array datatypes, e.g.:
+
+ my %where = (
+ array => { -value => [1, 2, 3] }
+ );
+
+which results in:
+
+ $stmt = 'WHERE array = ?';
+ @bind = ([1, 2, 3]);
