1：實現資料庫查詢指定記錄的四種方法 如：從十一到二十條：
//top
select top 10 * from admininfo as a where a.id not in(select top 10 id from admininfo )
//max
//首先
select top 10 id from admininfo
//其次
select max(id) from admininfo as a where a.id in(select top 10 id from admininfo)
//整合
select top 10 * from admininfo as b where b.id>(select max(id) from admininfo as a where a.id in(select top 10 id from admininfo)
);//between and
select * from admininfo where id between 11 and 20
//第四種最為常用
select * from (select *,row_number()over(order by id)as number from admininfo) as a where a.number between 11 and 20
2：sql中建立實現迴圈的儲存過程：
create procedure xuanhuan (@count int ) //create 關鍵字：procedure 方法名(「所需引數」)
as declare @num int ; //定義變數名
set @num=@count; //給變數名賦值
while(@num>0) //迴圈方法
begin //條件的開始
print @num; //輸出
set @num-=1; //迴圈賦值
end //條件的結束
exec dbo.xuanhuan 3 --執行儲存過程通過關鍵字exec 儲存過程的方法名 所需引數
3:通過sql實現分頁儲存過程
--通過關鍵字exec執行呼叫自定義方法並給指定引數
exec dbo.pagelistproc 1,5,'dbo.admininfo','*','id','asc'
create procedure pagelistproc (@pageindex int,
@pagesize int,@tablename varchar(200),@columnname varchar(500),@orderby varchar(50),@sort varchar(50)
)asdeclare @sql nvarchar(2000); --定義乙個查詢分頁的sql語句
--編寫sql查詢分頁 並將所需表，列，頁碼等用所傳的指定引數賦值替代
set @sql='select '+@columnname+' from(select '+@columnname+' ,row_number()over(order by '+@orderby+' )
as number from '+@tablename+' )t where t.number between '+cast(((@pageindex-1)*@pagesize)
as varchar(200))+' and '+ cast((@pagesize*@pageindex) as varchar(200))
--執行sql
exec(@sql);
SQL SERVER儲存過程實現分頁

sql server儲存過程實現批量刪除
在專案中用到了儲存過程來進行批量刪除的操作，給大家分享一下 原理就是把id組成的字串在資料庫分割成陣列放一張臨時表，刪除的時候與id進行對照 刪除會員資訊 ifobject id pro deluserinfo p is notnull 判斷儲存過程是否存在 drop proc pro deluse...
