MySQLdb - A DB API v2.0 compatible interface to MySQL.
|
||
|
|
|
||
|
|
This package is a wrapper around _mysql, which mostly implements the
|
||
|
|
MySQL C API.
|
||
|
|
|
||
|
|
connect() -- connects to server
|
||
|
|
|
||
|
|
See the C API specification and the MySQL documentation for more info
|
||
|
|
on other items.
|
||
|
|
|
||
|
|
For information on how MySQLdb handles type conversion, see the
|
||
|
|
MySQLdb.converters module.
