 Description   

This script works fine:

SET sql_mode='';
 
SET optimizer_switch='';

Now if I change sql_mode, the statement setting optimizer_switch starts to fail:

SET sql_mode=EMPTY_STRING_IS_NULL;
 
SET optimizer_switch='';


ERROR 1231 (42000): Variable 'optimizer_switch' can't be set to the value of 'NULL'
