sql基础语句（技巧）

1、压缩数据库

dbcc shrinkdatabase(dbname)

2、转移数据库给新用户已存在用户权限

exec sp_change_users_login'update_one','newgame','oldname'

go

3、检查备份集

RESTORE VERIFYONLY from disk='E\dvbbs.bak'

4、修复数据库

ALTER DATABASE [dvbbs] SET SINGLE_USER

GO

DBCC CHECKDB('dvbbs',repair_allow_data_loss)with tablelock

go

alter database[dvbbs] set multi_user

go

5、SQL SERVER写入循环

declare @i int

set @i=1

while @i<30

begin

insert into test(userid) values(@i)

set @i=@i+1

end

6、杀掉所有的事件探查器进程

DECLARE hcforeach CURSOR GLOBAL FOR SELECT 'kii' + RTRIM(spid) from master.dbo.sysprocesses where program_name in('SQL profiler',N'SQL事件探查器')

exec sp_msforecach_worker'?'

7、查看与某一个表相关的视图、存储过程、函数

select a.* from sysobjects a,syscomments b where a.id=b.id and b.text

like'%表名%'

8、查看当前数据库中所有存储过程

select name as 存储过程名称 from sysobjects where xtype='P'

9、查看主键列

select * from sysobjects where xtype='PK'

10、重建索引

ALTER INDEX Idx_name ON tblCompany REBUILD
