看看这一简单问题
SELECT id FROM users
现在,我要说的是,有<代码>id的用户订购了4、5、7、8,然后我不关心<>middle,最后我想最后一点是55、56、58。
So the returned rows would be something like this ( a new row)
4 // explicitly chose these as the start rows
5 // " "
7 // " "
8 // " "
44 // these just come in any order (order not important)
23 // " "
10 // " "
55 // explicitly chose these as the end rows
56 // " "
58 // " "
我怎么能对上述问题做修改? 增 编
