SqlServer操作大全(5)

   'Owner'    = user_name(uid)
from sysobjects
where user_name(uid)=@OldOwner
order by name
OPEN   curObject
FETCH NEXT FROM curObject INTO @Name, @Owner
WHILE(@@FETCH_STATUS=0)
BEGIN    
if @Owner=@OldOwner
begin
   set @OwnerName = @OldOwner + '.' + rtrim(@Name)
   exec sp_changeobjectowner @OwnerName, @NewOwner
end
-- select @name,@NewOwner,@OldOwner
FETCH NEXT FROM curObject INTO @Name, @Owner
END
close curObject
deallocate curObject
GO

10、SQL SERVER中直接循环写入数据
declare @i int
set @i=1
while @i<30
begin
    insert into test (userid) values(@i)
    set @i=@i+1
end
案例：
有如下表，要求就裱中所有沒有及格的成績，在每次增長0.1的基礎上，使他們剛好及格:
    Name     score
    Zhangshan   80
    Lishi       59
    Wangwu      50
    Songquan    69
while((select min(score) from tb_table)<60)
begin
update tb_table set score =score*1.01
where score<60
if  (select min(score) from tb_table)>60
  break
 else
    continue
end
 
数据开发-经典

1.按姓氏笔画排序:
Select * From TableName Order By CustomerName Collate Chinese_PRC_Stroke_ci_as //从少到多
2.数据库加密:
select encrypt('原始密码')
select pwdencrypt('原始密码')
select pwdcompare('原始密码','加密后密码') = 1--相同；否则不相同 encrypt('原始密码')
select pwdencrypt('原始密码')
select pwdcompare('原始密码','加密后密码') = 1--相同；否则不相同
3.取回表中字段:
declare @list varchar(1000),
@sql nvarchar(1000)
select @list=@list+','+b.name from sysobjects a,syscolumns b where a.id=b.id and a.name='表A'
set @sql='select '+right(@list,len(@list)-1)+' from 表A'
exec (@sql)
4.查看硬盘分区:
EXEC master..xp_fixeddrives
5.比较A,B表是否相等:
if (select checksum_agg(binary_checksum(*)) from A)
     =
    (select checksum_agg(binary_checksum(*)) from B)
print '相等'
else
print '不相等'
6.杀掉所有的事件探察器进程:
DECLARE hcforeach CURSOR GLOBAL FOR SELECT 'kill '+RTRIM(spid) FROM master.dbo.sysprocesses
WHERE program_name IN('SQL profiler',N'SQL 事件探查器')
EXEC sp_msforeach_worker '?'
7.记录搜索:
开头到N条记录
Select Top N * From 表
-------------------------------
N到M条记录(要有主索引ID)
Select Top M-N * From 表 Where ID in (Select Top M ID From 表) Order by ID   Desc
