Answer 1

since this question is still in top google results, maybe the answer might help someone:

a quick function that replaces the content between two characters. It should work with words as well, but I haven't test it with words. For deleting in the following string: "this is a [demo]"

the string between [ and ] do:

select deletestr("this is a [demo]" ,'[',']');

and the function:

 CREATE DEFINER=`replace_with_your_db`@`%` 
FUNCTION `deletestr` (`inputstr` TEXT CHARSET utf8, `fromstr` VARCHAR(10) CHARSET utf8, `tostr` VARCHAR(10) CHARSET utf8) RETURNS text CHARSET utf8
    NO SQL
RETURN
replace(inputstr,substr(inputstr, locate(fromstr,inputstr),locate(tostr,inputstr)-locate(fromstr,inputstr)+length(tostr)),'')
