SQL Server Top Clause 分页查询 Paging
写出一条Sql语句: 取出表A中第31到第40记录(SQLServer, 以自动增长的ID作为主键, 注意:ID可能不是连续的。)
4. 解1: select top 10 * from A where id not in (select top 30 id from A)
解2: select top 10 * from A where id > (select max(id) from (select top 30 id from A )as A)
评分标准: 写对即10分。(答案不唯一,datagrid 分页可能需要用到)
We all know the "TOP" clause returns the first n number of rows or percentage of rows thereby limiting the number of resulting rows displayed when we are selecting rows in a table.
