DDEESSCCRRIIPPTTIIOONN This is the "SQL::Library" model class. It provides access to "SQL::Library" via sql accessor. Additional caching options are pro- vided 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 query file is then re-loaded. This may slower the application a little bit, but should still be much faster then re-creating the SQL::Library instance on every load. Please refer to the "SQL::Library" for more information.
