int mysql_reset_connection(MYSQL *mysql)

Description

Resets the connection to clear the session state.

mysql_reset_connection() has effects similar to mysql_change_user() or an auto-reconnect except that the connection is not closed and reopened, and reauthentication is not done. The write set session history is reset. See Section 28.7.7.3, “mysql_change_user()”) and see Section 28.7.28, “C API Automatic Reconnection Control”).

The connection-related state is affected as follows:

Any active transactions are rolled back and autocommit mode is reset.
All table locks are released.
All TEMPORARY tables are closed (and dropped).
Session system variables are reinitialized to the values of the corresponding global system variables, including system variables that are set implicitly by statements such as SET NAMES.
User variable settings are lost.
Prepared statements are released.
HANDLER variables are closed.
The value of LAST_INSERT_ID() is reset to 0.
Locks acquired with GET_LOCK() are released.
