In my class I describe a sprawling SQL stored procedure we were looking at one day, with hundreds of lines of conditionals in a huge WHERE clause. Someone asked how anyone could have let it get this bad. I told them: “When there are only 2 or 3 conditionals, adding another one doesn’t make any difference. By the time there are 20 or 30 conditionals, adding another one doesn’t make any difference!”<br><br>
