mysql> Select STRCMP(10,10)As &#39;Equal Numbers&#39;, STRCMP(11,10)AS &#39;2nd Smaller&#39;, STRCMP(10,11)AS &#39;1st Smaller&#39;, STRCMP(10,NULL)As &#39;2nd NULL&#39;,STRCMP(NULL,10)AS &#39;1st NULL&#39;,STRCMP(NULL,NULL)AS &#39;Both NULL&#39;;
+---------------+-------------+-------------+----------+----------+-----------+
| Equal Numbers | 2nd Smaller | 1st Smaller | 2nd NULL | 1st NULL | Both NULL |
+---------------+-------------+-------------+----------+----------+-----------+
| 0             | 1           | -1          | NULL     | NULL     | NULL      |
