public StatementEmpty::fetch($mode = NULL, $cursor_orientation = NULL, $cursor_offset = NULL) Fetches the next row from a result set. See http://php.net/manual/pdo.constants.php for the definition of the constants used. Parameters $mode: One of the PDO::FETCH_* constants.

public StatementEmpty::fetchAllAssoc($key, $fetch = NULL) Returns the result set as an associative array keyed by the given field. If the given key appears multiple times, later records will overwrite earlier ones. Parameters $key: The name of the field on which to index the array. $fetch: The fetchmode to use.

public StatementEmpty::fetchAllKeyed($key_index = 0, $value_index = 1) Returns the entire result set as a single associative array. This method is only useful for two-column result sets. It will return an associative array where the key is one column from the result set and the value is another field. In most cases, the default of the first two columns is appropriate. Note that this method will run the result set to the end. Parameters $key_index: The numeric index of the field to use as the a

Empty implementation of a database statement. This class satisfies the requirements of being a database statement/result object, but does not actually contain data.
