将数据导入到了默认系统数据库master，现想删除，不能批量操作，请教。
------解决思路----------------------
SELECT 'drop table '+name+';' FROM sys.tables
------解决思路----------------------
--删除外键约束
DECLARE c1 cursor for
select 'alter table ['+ object_name(parent_obj) + '] drop constraint ['+name+']; '
from sysobjects
where xtype = 'F'
open c1
declare @c1 varchar(8000)
fetch next from c1 into @c1
while(@@fetch_status=0)
begin
exec(@c1)
fetch next from c1 into @c1
end
close c1
deallocate c1
--删除表
DECLARE c2 cursor for
select 'drop table ['+name +']; '
from sysobjects
where xtype = 'u'
open c2
declare @c2 varchar(8000)
fetch next from c2 into @c2
while(@@fetch_status=0)
begin
exec(@c2)
fetch next from c2 into @c2
end
close c2
deallocate c2

至少得限定下是用户表。
------解决思路----------------------
1、使用下面的语句
select 'drop table '+name+';' from sys.objects where type ='u'
2、将查询的结果再执行即可
------解决思路----------------------
sys.tables就是用户表

看样子像2008，SSMS里默认F7键是对象资源管理器，进入到表那一级，选中你要删除的表名，右键选删除，确认就行了
