    4th one - select *from employees where firstname like '%A' and len(Firstname)=6

      @stevequantie8064 2 ปีที่แล้ว +1

      Yes, as long as you're using the right reserved words like "length" vs "len". I think of "len" when using almost all other languages.

      I do not believe so. When you put the wildcard at the beginning, the logic would tell me to expand on the number of starting characters. Test it! I did and the author is correct with the simplest solution.
