Answer 1

Try this on your mysql prompt.

> mysql> create table t(i int);
>
> mysql> insert into t values(1),(2),(3);
>
> mysql> select i, if(i <= 1, 'low', 'high') from t order by i;
> +------+---------------------------+
> | i    | if(i <= 1, 'low', 'high') |
> +------+---------------------------+
> |    1 | low                       |
> |    2 | high                      |
> |    3 | high                      |
> +------+---------------------------+
