我有两个方面:
Permissions
- Permission_ID
- Permission_Desc
Users:
- User_ID
- User_Name
一个Fact_Tables
:
- User_ID
- Permission_ID
- Salary_Amt
现在我要做的是将User_ID 1的权限应用于User_2。将User_ID_1的权限复制到User_ID_2
如何在更新声明中执行此操作?
谢谢!
答案 0 :(得分:-1)
然而,如果我正确地理解了这个问题,我认为这应该可以完成工作:
Create Table #permissions (permission_id int, permission_desc
varchar(100))
insert into #permissions values (1, 'select'),(2,'insert')
Create Table #users (user_idd int, user_desc varchar(100))
insert into #users values (1, 'John'),(2,'Rohn')
Create Table #fact_table (user_idd int, permission_id int, sal int)
insert into #fact_table values (1,1,200), (2,2,300)
select * from #fact_table
update a set a.permission_id = b.permission_id from #fact_table a
inner join (
select (select user_idd from #fact_table where user_idd=2) user_idd,
permission_id, sal from #fact_table where permission_id = 1
) b on a.user_idd=b.user_idd
