2.事务处理

--常用语句就四个。

--Begin Transaction：标记事务开始。
--Commit Transaction：事务已经成功执行，数据已经处理妥当。
--Rollback Transaction：数据处理过程中出错，回滚到没有处理之前的数据状态，或回滚到事务内部的保存点。
--Save Transaction：事务内部设置的保存点，就是事务可以不全部回滚，只回滚到这里，保证事务内部不出错的前提下。

CREATE TABLE lives(Eat VARCHAR(200),Play VARCHAR(300),Numb int)

---开启事务
begin tran
--错误扑捉机制，看好啦，这里也有的。并且可以嵌套。
begin try  
   --语句正确
   insert into lives (Eat,Play,Numb) values ('猪肉','足球',1)
   --Numb为int类型，出错
   insert into lives (Eat,Play,Numb) values ('猪肉','足球','abc')
   --语句正确
   insert into lives (Eat,Play,Numb) values ('狗肉','篮球',2)
end try
begin catch
   select Error_number() as ErrorNumber,  --错误代码
          Error_severity() as ErrorSeverity,  --错误严重级别，级别小于10 try catch 捕获不到
          Error_state() as ErrorState ,  --错误状态码
          Error_Procedure() as ErrorProcedure , --出现错误的存储过程或触发器的名称。
          Error_line() as ErrorLine,  --发生错误的行号
          Error_message() as ErrorMessage  --错误的具体信息
   if(@@trancount>0) --全局变量@@trancount，事务开启此值+1，他用来判断是有开启事务
      rollback tran  ---由于出错，这里回滚到开始，第一条语句也没有插入成功。
end catch
if(@@trancount>0)
commit tran  --如果成功Lives表中，将会有3条数据。

--表本身为空表，ID ,Numb为int 类型，其它为nvarchar类型

        FETCH NEXT FROM My_Cursor INTO @filePath,@fileName;

  CLOSE My_Cursor; 
  DEALLOCATE My_Cursor;

4.强制删除被占用的数据库

---------------查询数据库是否被占用
select * from master.sys.sysprocesses where dbid = db_id('kaifengshitiyuju078000000jindiekisxingzhengshiyezhuanbanaccess_20190212015105_5705723296216269111')


---------------方法1：强制断开连接
declare @d varchar(8000)   
set   @d= ' '   
select   @d=@d+ '   kill   '+cast(spid   as   varchar)+char(13)   
from master.sys.sysprocesses where dbid=db_id('lankaoxianchengshiguanliju036000000yongyouruanjiangrpu8sqlserver_20190130115932_8149424311300407836')   
exec(@d) 

---------------方法2：立即回滚事务设置脱机状态，然后还需要手动删除数据文件
ALTER DATABASE [410225_cw]
SET OFFLINE with rollback IMMEDIATE
