--删除所有外键约束

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

2删除所有的表

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

以前在oracle中经常遇到没法删掉数据库的问题（因为一个用户对应一个数据库），所以必须要删除表（要先删除外检约束），在重新生成，今天在sql试了试，

成功了。

SQL批量删除用户表(先删除所有外键约束,再删除所有表)
--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' and object_name(parent_obj) like 'temptb_%'
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' and name like 'temptb_%'
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
