Name	Type	Default	Set	Range	Description
$query	string	required parameter	N/A	N/A	The complete SQL query
$max	?integer	Null	N/A	N/A	The maximum number of rows to affect (null: no limit)
$start	integer	0	N/A	N/A	The start row to affect
$fail_ok	boolean	False	N/A	N/A	Whether to output an error on failure
$get_insert_id	boolean	False	N/A	N/A	Whether to get an insert ID
$lang_fields	?array	Null	N/A	N/A	Extra language fields to join in for cache pre-filling / Tempcode, perhaps via the find_lang_fields function. You only need to send this if you are doing a JOIN and carefully craft your query so table field names won't conflict (null: none)
$field_prefix	string	Blank (empty string)	N/A	N/A	All the core fields have a prefix of this on them, so when we fiddle with language lookup we need to use this (only consider this if you're setting $lang_fields)
$save_as_volatile	boolean	False	N/A	N/A	Whether we are saving as a 'volatile' file extension (used in the XML DB driver, to mark things as being non-syndicated to Git)
