No it isn't. You have an extra set of []s in there. The "litral with bind" syntax is defined thus: \[ $sql_portion, $bind1, $bind2, $bind3,... ] Each $bindX element in turn can be in any format as defined at the end of this node (new formats are available since 0.08250): http://search.cpan.org/~ribasushi/DBIx-Class-0.08250/lib/DBIx/Class/ResultSet.pm#DBIC_BIND_VALUES > Second, what is the correct way to escape $query? There currently is no canned solution for this. The feature is blocked due to the unavailability of a way to mark some nodes as a specific dialect of SQL (per engine). In other words this is something which will take place post-Data::Query.
