请原谅我制定适当头衔的能力。
我有一个带有列的表：
+-------+----------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+----------+------+-----+---------+-------+
| name | char(20) | YES | | NULL | |
| pri | int(11) | YES | | NULL | |
| sec | int(11) | YES | | NULL | |
+-------+----------+------+-----+---------+-------+
像这样的数据
+--------+------+------+
| name | pri | sec |
+--------+------+------+
| first | 1 | 2 |
| second | 3 | 4 |
| third | 5 | 6 |
+--------+------+------+
我想要一个可以给出结果的选择：
+--------+------+
| name | addr |
+--------+------+
| first | 1 |
| first | 2 |
| second | 3 |
| second | 4 |
| third | 5 |
| third | 6 |
+--------+------+
任何帮助，将不胜感激。
尝试这个
SELECT name, pri AS addr
FROM Table1
WHERE pri is NOT NULL
UNION ALL
SELECT name, sec AS addr
FROM Table1
WHERE sec is NOT NULL
order by 1,2
