第3题：

这个sql语句怎么写?

有三个表如下

users(id,name);

type(id,name);

note(id,title,contents,user_id,author_id,type_id);

其中，user_id是作者、author_id是原创作者都是与users中的id进行关联的，type_id是分类编号，与type的id关联。

现在需要创建一个视图显示note中的id、title、contents、user_id、author_id、type_id、以及user_id、author_id、type_id对应的name。

怎样写sql语句呢？


思路：用游标通过系统表每次取一个字段update表a数据一次，将其它字段update成和该字段一样的值
DECLARE @fieldname varchar(200)
DECLARE test CURSOR FOR
select a.name from syscolumns a
join sysobjects b on a.id=b.id
where b.name='a' and a.colid<>1
--游标遍历系统表，查出a表所有字段,去掉第一个字段
OPEN test
FETCH NEXT FROM test into @fieldname
WHILE @@FETCH_STATUS = 0
BEGIN
update a set a.属性1=b.@fieldname,a.属性2=b.@fieldname,。。。a.属性n=b.@fieldname
from a a join a b on a.名称=b.名称
where b.@fieldname is not null
--这里可以改成通过系统条查出的字段名称拼成sql，这样就通用了，不管该表多少个字段也不用改sql了,时间关系我不写了.
end
CLOSE test
DEALLOCATE test

执行完后所有的属性字段的值都是一样的，随便取哪个字段都是你要的结果
注意，这段sql有条件限制，名称字段必须是该表的的第一个字段，如果不是的话把colid的值改成正确的
