module documentation

SQLite backend for the sqlite3 module in the standard library.
Constant FORMAT​_QMARK​_REGEX Undocumented
Class ​Database​Wrapper No class docstring; 0/8 class variable, 2/13 methods documented
Class ​SQLite​Cursor​Wrapper Django uses "format" style placeholders, but pysqlite2 uses "qmark" style. This fixes it -- but note that if you want to use a literal "%s" in a query, you'll need to use "%%s".

Function check​_sqlite​_version Undocumented
Function decoder Convert bytestrings from Python's sqlite3 interface to a regular string.
Function list​_aggregate Return an aggregate class that accumulates values in a list and applies the provided function to the data.

def decoder(conv_func):
Convert bytestrings from Python's sqlite3 interface to a regular string.
def list_aggregate(function):
Return an aggregate class that accumulates values in a list and applies the provided function to the data.
def none_guard(func):
Decorator that returns None if any of the arguments to the decorated function are None. Many SQL functions return NULL if any of their arguments are NULL. This decorator simplifies the implementation of this for the custom functions registered below.
