MySQL是否可以按顺序对两列进行排序?请参阅我的示例查询
<?php
$qResults = mysql_query("SELECT column1, column2 FROM tablename ORDER BY column1 ASC, column2");
//The initial data is these
Column 1 Column 2
7 24
18 3
2 25
9 23
17 8
1 15
10 19
20 4
11 6
16 5
//I want to sort it by this.
Column 1 Column 2
1 15
2 25
18 3
20 4
16 5
11 6
7 24
17 8
9 23
10 19

按升序对两列进行排序。这可能在mysql查询中吗?
