如何在 MySQL STRCMP() 函数中使用数值作为参数？

mysql> Select STRCMP(10,10)As 'Equal Numbers', STRCMP(11,10)AS '两nd Smaller', STRCMP(10,11)AS '1st Smaller', STRCMP(10,NULL)As '二nd NULL',STRCMP(NULL,10)AS '1st NULL',STRCMP(NULL,NULL)AS 'Both NULL';
+---------------+-------------+-------------+----------+----------+-----------+
| Equal Numbers | 两nd Smaller | 1st Smaller | 二nd NULL | 1st NULL | Both NULL |
+---------------+-------------+-------------+----------+----------+-----------+
| 0             | 1           | -1          | NULL     | NULL     | NULL      |
+---------------+-------------+-------------+----------+----------+-----------+
