SQL Server利用RowNumber()内置函数与Over关键字实现通用分页存储过程,支持单表或多表结查集分页,存储过程如下:
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

/******************/
create
procedure
[dbo].[sp_DataPaging]
(
@selectsql nvarchar(200),
--查询字段SQL,不含select,支持灵活写法,如:col1,col3,isnull(col4,'') as col4
@fromsql nvarchar(500),
--查询表及条件SQL,不含from,若包含条件请加上where,如:table where col1='test'
@orderbysql nvarchar(100),
--查询排序SQL,不含order by,如:id order by desc
@pagesize
int
=20,
--每页显示记录数
@pageno
int
=1,
--当前查询页码,从1开始
@returnrecordcount
bit
=1
--是否需要返回总记录数,若设为1,则返回两个结果表
)
as
begin
declare
@sqlcount nvarchar(500),@sqlstring nvarchar(
max
)
set
@sqlstring=N
'from (select row_number() over (order by '
+ @orderbysql + N
') as rowId,'
+ @selectsql + N
' from '
+ @fromsql +N
') as t'
if(@returnrecordcount=1)
begin
set
@sqlcount=N
'select count(rowId) as resultcount '
+ @sqlstring
exec
(@sqlcount)
end
set
@sqlstring=N
'select * '
+ @sqlstring +
' where rowId between '
+
convert
(nvarchar(50),(@pageno-1)*@pagesize+1)+
' and '
+
convert
(nvarchar(50),@pageno*@pagesize)
exec
(@sqlstring)
end

用法如下:
1
2
3
4
5
6
7

--单表查询
exec
[dbo].[sp_DataPaging]
'*'
,
'AssetDetail'
,
'assetsingleno'
,10,1
--多表查询
exec
[dbo].[sp_DataPaging]
'a.*'
,
'Inventory a left join AssetDetail b
on a.StoreNo=b.StoreNo and a.CompanyID=b.CompanyID
inner join Asset c on b.AssetID=c.ID and b.CompanyID=c.CompanyID'
,
'a.id'
,20,3,1
|
结果显示如下(如上多表查询):
