求教一句sql查询语句
具体情况是在一张表内有两个字段，假设为 ：num1 num2
分别表示开始数字与结束数字，例如有数据为:
1 10
11 20
21 30
31 40
41 50
以上5条数据；

现在我这里给予的查询条件是一个区间，比如是13-35
查询到的数据应该是后面四条，请问，这种情况如何查询比较好？


[解决办法]

SQL code

--> 测试数据：[tb]IF OBJECT_ID('[tb]') IS NOT NULL DROP TABLE [tb]GO CREATE TABLE [tb]([num1] INT,[num2] INT)INSERT [tb]SELECT 1,10 UNION ALLSELECT 11,20 UNION ALLSELECT 21,30 UNION ALLSELECT 31,40 UNION ALLSELECT 41,50 UNION ALLSELECT 20,10 --增加一个[num2]>[num1]的--------------开始查询----------------------------13-35--应该是下面三行才合理吧SELECT * FROM [tb] WHERE [num2]>13 AND [num2]>[num1] AND [num1]<35----------------结果----------------------------/* num1        num2----------- -----------11          2021          3031          40(3 行受影响)*/
