mysql - Using lower() in a trigger after declaring a variable -


i want set variable have declared in mysql lowercase in trigger using code

declare last_inserted_number varchar(100) default '0800100200'; declare last_inserted_message varchar(100) default 'lorem ipsum';  set last_inserted_number = new.dest_msisdn; set last_inserted_message = lower(new.text_message);

set last_inserted_message = lower(new.text_message); not throw error although suspect may have used lower() in wrong way when wrote lower(new.text_message)

should using lower() in way?.

the use of lower() in question should work without flaws.

the circumstance lower() doesn't work on binary (varbinary, blob) input.
