SQL Server通用分页存储过程

SQL Server通用分页存储过程,用存储过程可以提高效率与节约时间。

IF EXISTS(SELECT * FROM SYSOBJECTS WHERE name = 'commonPagination')

DROP PROC commonPagination

GO



CREATE proc [dbo].[commonPagination] 

@columns varchar(500), --要显示的列名,用逗号隔开 

@tableName varchar(100), --要查询的表名 

@orderColumnName varchar(100), --排序的列名 

@order varchar(50), --排序的方式,升序为asc,降序为 desc 

@where varchar(100), --where 条件,如果不带查询条件,请用 1=1 

@pageIndex int, --当前页索引 

@pageSize int, --页大小(每页显示的记录条数) 

@pageCount int output --总页数,输出参数 

as 

begin 

declare @sqlRecordCount nvarchar(1000) --得到总记录条数的语句 

declare @sqlSelect nvarchar(1000) --查询语句 

set @sqlRecordCount=N'select @recordCount=count(*) from ' 

+@tableName + ' where '+ @where 

declare @recordCount int --保存总记录条数的变量 

exec sp_executesql @sqlRecordCount,N'@recordCount int output',@recordCount output 

--动态 sql 传参 

if( @recordCount % @pageSize = 0) --如果总记录条数可以被页大小整除 

set @pageCount = @recordCount / @pageSize --总页数就等于总记录条数除以页大小 

else --如果总记录条数不能被页大小整除 

set @pageCount = @recordCount / @pageSize + 1 --总页数就等于总记录条数除以页大小加1 

set @sqlSelect = 

N'select '+@columns+' from ( 

select row_number() over (order by ' 

+@orderColumnName+' '+@order 

+') as tempid,* from ' 

+@tableName+' where '+ @where 

+') as tempTableName where tempid between ' 

+str((@pageIndex - 1)*@pageSize + 1 ) 

+' and '+str( @pageIndex * @pageSize) 

exec (@sqlSelect) --执行动态Sql 

end 

 

--以下是调用示例
use pubs
go
declare @pageCount int
exec commonPagination
'job_id,job_desc','jobs','job_id',
'asc','1=1',2,2,@pageCount output
select '总页数为:' + str(@pageCount)
