sqlserver 通用分页存储过程

create proc 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
go
–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)
