我的数据库中有一个这样的表（SQL Server 2008）
ID Type Desc
--------------------------------
C-0 Assets No damage
C-0 Environment No impact
C-0 People No injury or health effect
C-0 Reputation No impact
C-1 Assets Slight damage
C-1 Environment Slight environmental damage
C-1 People First Aid Case (FAC)
C-1 Reputation Slight impact; Compaints from local community
我必须将资产、人员、环境和声誉显示为列，并将匹配的描述显示为值。但是当我运行数据透视查询时，我的所有值都是空的。
有人可以查看我的查询并告诉我哪里做错了吗？
Select severity_id,pt.[1] As People, [2] as Assets , [3] as Env, [4] as Rep
FROM
(
select * from COMM.Consequence
) As Temp
PIVOT
(
max([DESCRIPTION])
FOR [TYPE] In([1], [2], [3], [4])
) As pt
这是我的输出
ID People Assets Env Rep
-----------------------------------
C-0 NULL NULL NULL NULL
C-1 NULL NULL NULL NULL
C-2 NULL NULL NULL NULL
C-3 NULL NULL NULL NULL
C-4 NULL NULL NULL NULL
C-5 NULL NULL NULL NULL
Select severity_id, pt.People, Assets, Environment, Reputation
FROM
(
select * from COMM.Consequence
) As Temp
PIVOT
(
max([DESCRIPTION])
FOR [TYPE] In([People], [Assets], [Environment], [Reputation])
) As pt
