我目前正在运行sql Server 2008并尝试获取以下子查询数据：
ID | Field Name | Field Selection 1 | Rating 1 | Good 1 | Rating 2 | Good 1 | Rating 3 | Bad 2 | Rating 1 | OK
根据ID列分组为一行：
ID | Rating 1 | Rating 2 | Rating 3 1 | Good | Good | Bad 2 | OK | NULL | NULL
这可能吗？提前致谢！
干杯,

解决方法
您可以使用sql Server pivot子句：
select
p.*
from Table1
pivot(
max([Field Selection])
for [Field Name] in ([Rating 1],[Rating 2],[Rating 3])
) as p
或者你可以手动转动：
select
ID,max(case when [Field Name] = 'Rating 1' then [Field Selection] end) as [Rating 1],max(case when [Field Name] = 'Rating 2' then [Field Selection] end) as [Rating 2],max(case when [Field Name] = 'Rating 3' then [Field Selection] end) as [Rating 3]
from Table1
group by ID
