SQL Server 存储过程分页

感兴趣的小伙伴,下面一起跟随编程之家 jb51.cc的小编两巴掌来看看吧!

代码如下:


--使用说明 本代码适用于Mssql2000,对于其它数据库也可用.但没必要 
--创建存储过程 
CREATE PROCEDURE pagination 
@tblName varchar(255),-- 表名 
@strGetFields varchar(1000) = '*',-- 需要返回的列 
@fldName varchar(255)='',-- 排序的字段名(可包含如TABLE.FLDNAME形式) 
@PageSize int = 10,-- 页尺寸 
@PageIndex int = 1,-- 页码 
@doCount bit = 0,-- 返回记录总数,非 0 值则返回 
@OrderType bit = 0,-- 设置排序类型,非 0 值则降序 
@strWhere varchar(1500) = '' -- 查询条件 (注意: 不要加 where) 
AS 
declare @strsql varchar(5000) -- 主语句 
declare @strTmp varchar(110) -- 临时变量 
declare @strOrder varchar(400) -- 排序类型 
declare @fldName_t varchar(255) -- 在分页时用的排序字段名,不包含多表并列时的表名 
set @fldName_t = right(@fldName,len(@fldName)-CHARINDEX('.',@fldName)) 
if @doCount != 0 
begin 
if @strWhere !='' 
set @strsql = 'select count(*) as Total from ' + @tblName + ' where '+@strWhere 
else 
set @strsql = 'select count(*) as Total from ' + @tblName + '' 
end 
--以上代码的意思是如果@doCount传递过来的不是0,就执行总数统计。以下的所有代码都是@doCount为0的情况 
else 
begin 
if @OrderType != 0 
begin 
set @strTmp = '<(select min' 
set @strOrder = ' order by ' + @fldName +' desc' 
--如果@OrderType不是0,就执行降序,这句很重要! 
end 
else 
begin 
set @strTmp = '>(select max' 
set @strOrder = ' order by ' + @fldName +' asc' 
end 
if @PageIndex = 1 
begin 
if @strWhere != '' 
set @strsql = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from ' + @tblName + ' where ' + @strWhere + ' ' + @strOrder 
else 
set @strsql = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from '+ @tblName + ' '+ @strOrder 
--如果是第一页就执行以上代码,这样会加快执行速度 
end 
else 
begin 
--以下代码赋予了@strsql以真正执行的sql代码 
set @strsql = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from '+ @tblName + ' where ' + @fldName + ' ' + @strTmp + ' ('+ @fldName_t + ') from (select top ' + str((@PageIndex-1)*@PageSize) + ' '+ @fldName + ' from ' + @tblName + '' + @strOrder + ') as tblTmp)'+ @strOrder 
if @strWhere != '' 
set @strsql = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from '+ @tblName + ' where ' + @fldName + ' ' + @strTmp + ' ('+ @fldName_t + ') from (select top ' + str((@PageIndex-1)*@PageSize) + ' '+ @fldName + ' from ' + @tblName + ' where ' + @strWhere + ' '+ @strOrder + ') as tblTmp) and ' + @strWhere + ' ' + @strOrder 
end 
end 
exec (@strsql) 
go 
--测试 
create table news --建表 
( 
n_id int iDENTITY(1,1) primary key,n_title char(200),n_content text 
) 
--写循环插入1000000条的数据 
create proc tt 
as 
declare @i int 
set @i=0 
while(@i<1000000) 
begin 
insert into news(n_title,n_content) values('sb','dsfsdfsd') 
set @i=@i+1 
end 
exec tt 
exec pagination 'news','*','n_id',1000,2,''

代码如下:


自己改写的一个分页存储过程 
CREATE PROC Paging 
( 
@pageSize int,@pageIndex int,@pageField nvarchar(32),@countTotal bit=1,@fieldQuery nvarchar(512),@tableQuery nvarchar(512),@whereQuery nvarchar(2048),@orderQuery nvarchar(512) 
) 
AS 
DECLARE @bdate Datetime 
SET @bdate = getdate() 
DECLARE @itemcount int 
SET @itemcount=@pageIndex*@pageSize 
DECLARE @itemlowwer int 
SET @itemlowwer=(@pageIndex-1)*@pageSize 
DECLARE @cmd nvarchar(3062) 

IF @pageIndex=1 
SET @cmd ='SELECT TOP ‘+CAST(@pageSize AS NVARCHAR)+' ‘+@fieldQuery+' FROM ‘+@tableQuery+' WHERE ‘+@whereQuery+' ORDER BY ‘+@orderQuery 
ELSE 
SET @cmd='SELECT ‘+@fieldQuery+' FROM ‘+@tableQuery+' WHERE ‘+@pageField+' IN (SELECT TOP ‘+CAST(@itemcount as nvarchar)+' ‘+@pageField+' FROM ‘+@tableQuery+' WHERE ‘+@whereQuery+' ORDER BY ‘+ @orderQuery+') 
AND ‘+@pageField+' NOT IN (SELECT TOP ‘ +CAST(@itemlowwer as nvarchar)+' ‘+@pageField+' FROM ‘+@tableQuery+' WHERE ‘+@whereQuery+' ORDER BY ‘+ @orderQuery+')' 
–print @cmd 
EXEC(@cmd) 

SELECT DATEDIFF( ms,@bdate,getdate() ) 

IF @countTotal =1 
BEGIN 
SET @cmd = ‘SELECT COUNT( 0) FROM ‘+@tableQuery+' WHERE ‘+@whereQuery 
EXEC(@cmd) 
END 
GO
