问一个简单的触发器问题
触发器如下：
create trigger trgaa
on Emp1
for update
as
if(update(Age))
begin
update Emp1 set GZ=GZ+1 where Code=????
end

当我更新某一行年龄时，要将这一行的GZ+1。那我在触发器里怎么写where条件啊？？

Code为主键。

[解决办法]
create trigger trgaa
on Emp1
for update
as
if(update(Age))
begin
update Emp1 from deleted d set GZ=GZ+1 where Code=d.code
end

[解决办法]
update Emp1 set GZ=GZ+1 where Code in (select code from deleted)
