The directory where the queries are saved is controlled by the variable $ADODB_CACHE_DIR
$cacheSecs sets the default value of the time in seconds that cached queries are saved. If not set then the value is 3600. It can be set via either a normal connection object or a DSN type connection configuration.
This default value can be overridden on a query by query basis
/* * A connection object assumed */ $ADODB_CACHE_DIR = 'd:/queries'; $db->cacheSecs = 6000;
