利用sql批量删除表，存储过程。

最近用godaddy的空间，由于系统里面的表多，一个个的删除很麻烦，就网上搜集了一下解决方法。

给大家分享一下：

   1.批量删除存储过程  declare @procName varchar(500)

      declare cur cursor

            for select [name] from sys.objects where type = p

      open cur

      fetch next from cur into @procName

      while @@fetch_status = 0

      begin

            if @procName <> DeleteAllProcedures

                  exec(drop procedure + @procName)

                  fetch next from cur into @procName

      end

      close cur

      deallocate cur
2，批量删除外键

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
3.批量删除表

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
--批量清除表内容：

--1.禁用外键约束
DECLARE c1 cursor for
    select alter table [+ object_name(parent_obj) + ] nocheck 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.清除表内容
DECLARE c2 cursor for
    select truncate 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
--3.启用外键约束
DECLARE c1 cursor for
    select alter table [+ object_name(parent_obj) + ] check 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
