|
o escape method: for escaping values send to MySQL
|
o quoting method: for quoting values send to MySQL in statements
|
o conversion mapping: maps Python and MySQL data types to
|
function for converting them.
|
|
Whenever one needs to convert values differently, a converter_class
|
argument can be given while instantiating a new connection like
|
cnx.connect(converter_class=CustomMySQLConverterClass).

leave it None and return it right away. The actual conversion
