Code

protected function getPrefixInfo($table = 'default', $add_prefix = TRUE) {
 $info = array(
 'schema' => $this->defaultSchema ,
 'prefix' => $this->connection 
 ->tablePrefix ($table),
 );
 if ($add_prefix) {
 $table = $info['prefix'] . $table;
 }
 // If the prefix contains a period in it, then that means the prefix also
 // contains a schema reference in which case we will change the schema key
 // to the value before the period in the prefix. Everything after the dot
 // will be prefixed onto the front of the table.
 if (($pos = strpos ($table, '.')) !== FALSE) {
 // Grab everything before the period.
 $info['schema'] = substr ($table, 0, $pos);
 // Grab everything after the dot.
