Thank you for the report. Verified as described. But as "select charset(DAYNAME(now()));" returns binary this can be considered as "Not a Bug". See also bug #24297

Please check MONTHNAME() as well; I find no mention that the return value is binary, and there is no reason it should be.

But return value is binary: $mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1179 Server version: 5.1.20-beta-debug Source distribution Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql> mysql> select charset(MONTHNAME(now())); +---------------------------+ | charset(MONTHNAME(now())) | +---------------------------+ | binary | +---------------------------+ 1 row in set (0.00 sec) mysql> \q Bye

Hi, sorry, but my request was select lower(substring(DAYNAME(now()),1,3)) not select charset(DAYNAME(now()))

I've encountered something possibly related, the statement: CONCAT( 'M', LPAD( 1, 6, '0' )) Gives M000001, so I would expect LOWER(CONCAT( 'M', LPAD( 1, 6, '0' ))) to return m000001, however it returns M000001. However, LOWER( CONCAT( 'M', LPAD( CAST( id AS CHAR ) , 6, '0' ) ) ) behaves as expected.

Character set of the MONTHNAME/DAYNAME function result has been changed to system charset.
