DESCRIPTION This is the "SQL::Library" model class. It provides access to "SQL::Library" via sql accessor. Additional caching options are provided for increased performance via sqlcache and sqlcache_use_mtime, these options can only be used when sql strings are stored within a file and loaded by using a scalar value passed to load. The load and parse phase is then bypassed if cached version of the file is found. The use of these options can result in more memory being used but faster access to query data when running under persistent environment such as mod_perl or FastCGI. When sqlcache_use_mtime is in use, last modification time of the file is being referenced upon every cache check. If the modification time has changed only then query file is re-loaded. This should be much faster then re-creating the SQL::Library instance on every load. Please refer to the "SQL::Library" for more information. METHODS new Initializes database connection $self->load Initializes "SQL::Library" instance $self->dbh Returns the current database handle. $self->sql Returns the current "SQL::Library" instance SEE ALSO Catalyst, DBI AUTHOR Alex Pavlovic, "alex.pavlovic@taskforce-1.com" COPYRIGHT This program is free software, you can redistribute it and/or modify it under the same terms as Perl itself.
