为了进行比较，我们可以在 STRCMP() 函数中使用数值作为参数。它们作为参数给出，不带引号。下面的示例将对其进行演示。
示例
mysql> Select STRCMP(10,10)As 'Equal Numbers', STRCMP(11,10)AS '2nd Smaller', STRCMP(10,11)AS '1st Smaller', STRCMP(10,NULL)As '2nd NULL',STRCMP(NULL,10)AS '1st NULL',STRCMP(NULL,NULL)AS 'Both NULL';
+---------------+-------------+-------------+----------+----------+-----------+
| Equal Numbers | 2nd Smaller | 1st Smaller | 2nd NULL | 1st NULL | Both NULL |
+---------------+-------------+-------------+----------+----------+-----------+
| 0 | 1 | -1 | NULL | NULL | NULL |
+---------------+-------------+-------------+----------+----------+-----------+
