SET CHARACTER SET

Syntax

SET {CHARACTER SET | CHARSET}
    {charset_name | DEFAULT}

Description

Sets the character_set_client and character_set_results session system variables to the specified character set and collation_connection to the value of collation_database, which implicitly sets character_set_connection to the value of character_set_database.

This maps all strings sent between the current client and the server with the given mapping.

Example

SHOW VARIABLES LIKE 'character_set\_%';
