You can execute the SET NAMES statement to specify character sets. This statement sets character_set_client, character_set_connection, and character_set_results to the specified character set.

Syntax

SET NAMES {'charset_name'
    [COLLATE 'collation_name'] | DEFAULT}
You do not need to enclose charset_name or collation_name in single quotation marks ('). If you specify the collation_name parameter, the collation is set to the specified value.

Examples
