Is "SET CHARACTER SET utf8" necessary? - https://stackoverflow.com/questions/1566602/is-set-character-set-utf8-necessary

Using SET CHARACTER SET utf8 after using SET NAMES utf8 will actually reset the character_set_connection and collation_connection to @@character_set_database and @@collation_database respectively.

The manual states that

SET NAMES x is equivalent to

SET character_set_client = x;
SET character_set_results = x;
