LEAST()函式是GREATEST()函式的相反函式。其目的是為了從列表值返回至少值項(N1，N2，N3，等等)。下面的例子顯示了LEAST()函式適當的使用和輸出：
mysql>SELECT LEAST(3,5,1,8,33,99,34,55,67,43); +---------------------------------------------------------+ | LEAST(3,5,1,8,33,99,34,55,67,43) | +---------------------------------------------------------+ | 1 | +---------------------------------------------------------+ 1 row in set (0.00 sec)
