Sql Server存储过程分页总结
分页方案一：(利用Not In和SELECT TOP分页)语句形式：
SELECT TOP 10 *
FROM TestTable
WHERE (ID NOT IN
(SELECT TOP 20 id
FROM TestTable
ORDER BY id))
ORDER BY ID
SELECT TOP 页大小 *
FROM TestTable
WHERE (ID NOT IN
(SELECT TOP 页大小*页数 id
FROM 表
ORDER BY id))
ORDER BY ID
分页方案二：
语句形式：
Create PROCEDURE ListPage(
@tblName nvarchar(200), ----要显示的表或多个表的连接
@fldName nvarchar(200) = '*', ----要显示的字段列表
@pageSize int = 10, ----每页显示的记录个数
@page int = 1, ----要显示那一页的记录
@pageCount int = 1 output, ----查询结果分页后的总页数
@Counts int = 1 output, ----查询到的记录数
@fldSort nvarchar(100) = null, ----排序字段列表或条件
@Sort bit = 0, ----排序方法，0为升序，1为降序
@strCondition nvarchar(200) = null, ----查询条件,不需where
@ID nvarchar(50) ----主表的主键
)
AS
SET NOCOUNT ON
Declare @sqlTmp nvarchar(1000) ----存放动态生成的SQL语句
Declare @strTmp nvarchar(1000) ----存放取得查询结果总数的查询语句
Declare @strID nvarchar(1000) ----存放取得查询开头或结尾ID的查询语句
Declare @sqlSort nvarchar(200) ----存放临时生成的排序条件
Declare @intCounts int ----要移动的记录数
Declare @BeginID int ----开始的ID
Declare @EndID int ----结束的ID
--------首先生成排序方法---------
if @Sort=0 --升序
begin
if not(@fldSort is null)
set @sqlSort = ' Order by ' + @fldSort
else
set @sqlSort = ' Order by ' + @ID
end
else --降序
begin
if not(@fldSort is null)
set @sqlSort = ' Order by ' + @fldSort + ' DESC'
else
set @sqlSort = ' Order by ' + @ID + ' DESC '
end
--------生成查询语句--------
--此处@strTmp为取得查询结果数量的语句
if @strCondition is null --没有设置显示条件
begin
set @sqlTmp = @fldName + ' From ' + @tblName
set @strTmp = 'select @Counts=Count(' + @ID + ') FROM '+@tblName
set @strID = ' From ' + @tblName
end
else
begin
set @sqlTmp = + @fldName + 'From ' + @tblName + ' where ' + @strCondition
set @strTmp = 'select @Counts=Count(' + @ID + ') FROM '+@tblName + ' where ' + @strCondition
set @strID = ' From ' + @tblName + ' where ' + @strCondition
end
----取得查询结果总数量-----
exec sp_executesql @strTmp,N'@Counts int out ',@Counts out
--取得分页总数
if @Counts <= @pageSize
set @pageCount = 1
else
set @pageCount = (@Counts / @pageSize) + 1
--计算要移动的记录数
if @page = 1
set @intCounts = @pageSize
else
begin
set @intCounts = (@page-1) * @pageSize + 1
end
-----取得分页后此页的第一条记录的ID
set @strID = 'select @BeginID=' + @ID + ' ' + @strID
set @intCounts = @intCounts - @pageSize + 1
set rowcount @intCounts
exec sp_executesql @strID,N'@BeginID int out ',@BeginID out
-----取得分页后此页的最后一条记录的ID
set @intCounts = @intCounts + @pageSize - 1
print @intCounts
set rowcount @intCounts
exec sp_executesql @strID,N'@BeginID int out ',@EndID out
------恢复系统设置-----
set rowcount 0
SET NOCOUNT OFF
------返回查询结果-----
if @strCondition is null
set @strTmp = 'select ' + @sqlTmp + ' where ' + @ID + ' between ' + str(@BeginID) + ' and ' + str(@EndID)
else
set @strTmp = 'select ' + @sqlTmp + ' where ' + @ID +' (between ' + str(@BeginID) + ' and ' + str(@EndID) + ') and ' + @strCondition
if not(@sqlSort is null)
set @strTmp = @strTmp + @sqlSort
exec sp_executesql @strTmp
GO
分页方案三：
语句形式：
create PROCEDURE sy_more_cs
(
@mode int=0,
@pagesize int=10,
@pageindex int=1
)
AS
SET NOCOUNT ON
if @mode=0
begin
select count(*) as 记录数 from dbo.house_info_cs;
end
else
begin
declare @indextable table(id int identity(1,1),nid int)
declare @PageLowerBound int
declare @PageUpperBound int
set @PageLowerBound=(@pageindex-1)*@pagesize
set @PageUpperBound=@PageLowerBound+@pagesize
insert into @indextable(nid) select from dbo.house_info_cs order by dt desc;
select ls.* from dbo.house_info_cs ls,@indextable t where ls.id=t.nid
and t.id>@PageLowerBound and t.id<=@PageUpperBound order by t.id
end
