LEAST()函数是GREATEST()函数的相反函数。其目的是为了从列表值返回至少值项(N1，N2，N3，等等)。下面的例子显示了LEAST()函数适当的使用和输出：
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 |
+---------------------------------------------------------+
