 There are a few parsing modes you may be interested in:

+<u>**Double-quotes for literal strings**</u>
 
 MySQL uses both double quotes and single quotes to declare literal strings.  This is not ansi behaviour, but it is more forgiving for programmers coming from other languages. A specific parse function is provided: 
 
     result = parse_mysql(sql)

 The default output for this parser is to emit a null function `{"null":{}}` wherever `NULL` is encountered in the SQL.  If you would like something different, you can replace nulls with `None` (or anything else for that matter):

-#### Normalized function call form
+<u>**Normalized function call form**</u>
 
 The default behaviour of the parser is to output function calls in `simple_op` format: The operator being a key in the object; `{op: params}`.  This form can be difficult to work with because the object must be scanned for known operators, or possible optional arguments, or at least distinguished from a query object.
