Sql Service中的分页
创建存储过程如下:
1 CREATE PROCEDURE [dbo].[sp_GetPageList] 2 @TableName varchar(5000), --表名 3 @SelectFields varchar(5000) = '*', --字段名(全部字段为*) 4 @OrderField varchar(5000), --排序字段(必须!支持多字段) 5 @sqlWhere varchar(5000) = Null,--条件语句(不用加where) 6 @pageSize int, --每页多少条记录 7 @pageIndex int = 1 , --指定当前为第几页 8 @totalRecord int = 0 OUTPUT, 9 @TotalPage int output --返回总页数 10 AS 11 BEGIN 12 Begin Tran --开始事务 13 Declare @sql nvarchar(4000); 14 print @totalRecord 15 --if @totalRecord<=0 begin 16 --计算总记录数 17 if (@SqlWhere='' or @sqlWhere is NULL) 18 set @sql = 'select @totalRecord = count(*) from ' + @TableName 19 else 20 set @sql = 'select @totalRecord = count(*) from ' + @TableName + ' where ' + @sqlWhere 21 22 EXEC sp_executesql @sql,N'@totalRecord int OUTPUT',@totalRecord OUTPUT--计算总记录数 23 --end 24 --计算总页数 25 select @TotalPage=CEILING((@totalRecord+0.0)/@PageSize) 26 if (@SqlWhere='' or @sqlWhere is NULL) 27 set @sql = 'Select * FROM (select ROW_NUMBER() Over(order by ' + @OrderField + ') as rowId,' + @Fields + ' from ' + @TableName 28 else 29 set @sql = 'Select * FROM (select ROW_NUMBER() Over(order by ' + @OrderField + ') as rowId,' + @Fields + ' from ' + @TableName + ' where ' + @SqlWhere 30 --处理页数超出范围情况 31 if @PageIndex<=0 32 Set @pageIndex = 1 33 if @pageIndex>@TotalPage 34 Set @pageIndex = @TotalPage 35 --处理开始点和结束点 36 Declare @StartRecord int 37 Declare @EndRecord int 38 set @StartRecord = (@pageIndex-1)*@PageSize + 1 39 set @EndRecord = @StartRecord + @pageSize - 1 40 --继续合成sql语句 41 set @Sql = @Sql + ') as t where rowId between ' + Convert(varchar(50),@StartRecord) + ' and ' + Convert(varchar(50),@EndRecord) 42 print @sql 43 Exec(@Sql) 44 --------------------------------------------------- 45 If @@Error <> 0 46 Begin 47 RollBack Tran 48 Return -1 49 End 50 Else 51 Begin 52 Commit Tran 53 Return @totalRecord ---返回记录总数 54 End 55 END
