代码如下:
create procedure [dbo].[CommonDataPager] ( --用途:分页查询记录信息 --以下是几个参数的说明: --1.@tbName:表示表名 --2.@PrimaryKey:表的主键 --3.@searchCount:返回的结果数 --4.@fldNames:字段名,多个字段以逗号分割 --5.@PageSize:每页显示的记录数,如果为0,则表示不要分页,直接得到搜索、排序后的所有记录 --6.@PageIndex:当前页的索引 --7.@Filter:搜索条件,即在“where”后面写条件 --8.@Sort:排序项,即在“order by”后面写排序项 --9.@joinTable:连接其他表 @tbName varchar(3000), @PrimaryKey varchar (255), @searchCount int output, @fldNames varchar(3000)='*', @PageSize int= 0, @PageIndex int= 1, @Filter nvarChar (3000)='', @Sort varchar (3000)='', @joinTable nvarchar(3000)='' --调用的时候,可以类似如:as a inner join departInfo as b on a.departInfoId=b.Id ) as declare @start nvarchar (100) declare @end nvarchar (100) declare @m_WhereString varchar(4000) declare @sqlString nvarchar(4000) --动态拼接的SQL语句 declare @orderString nvarchar (4000) if(@PageSize < 0) begin set @PageSize=0; end if(@PageIndex < 1) begin set @PageIndex=1; end set @start = ltrim(rtrim(Cast((@PageSize*(@PageIndex - 1)+1) as varchar (100)))) --开始记录 set @end =ltrim(rtrim(Cast((@PageSize * @PageIndex) as varchar (100)))) --结束记录 set @m_WhereString='' if(len(ltrim(rtrim(@Filter))) > 0) begin set @m_WhereString = ' where ' + @Filter; end if (len (ltrim (rtrim (@Sort))) > 0) begin set @orderString = ' order by ' + @Sort; end else begin set @orderString = ' order by ' + @PrimaryKey + ' asc ' end declare @sqlStringOutput nvarchar(3000) set @sqlStringOutput=N'select @searchCount=count(*) from ' + @tbName + ' ' + @joinTable + ' ' + @m_WhereString; exec sp_executesql @sqlStringOutput,N'@searchCount int output',@searchCount output if (@PageSize = 0) begin --得到所有的搜索记录,并且不分页 set @sqlString='select ' + @fldNames + ' from ' + @tbName + @m_WhereString + ' ' + @orderString; end else begin --实现分页效果,并且根据搜索条件过滤、分页、排序 set @sqlString='select * from (select row_number() over('+ @orderString +') as myNewId,' + @fldNames + ' from ' + @tbName + ' ' + @joinTable + ' ' + @m_WhereString + ' ) as MyTempTable where myNewId between '+ @start +' and '+ @end +' order by myNewId asc' ; end exec(@sqlString) go
