首页 上页 下页 尾页 [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] [23] [24] [25] [26] [27] [28] [29] [30] [31] [32] [33] [34] [35] [36] [37] [38] [39] [40] [41] [42] [43] [44] [45] [46] [47] [48] [49] [50]

(select   top '+cast((@recsperpage*(@page-1)) as varchar(20))+' '+@id+' from ('+@sql+') t9 order by '+@sort+') order by '+@sort

print @str

exec sp_executesql @str
go

其实，以上语句可以简化为：

select top 页大小 *

from table1

where (id not in

          (select top 页大小*页数 id

         from 表
