Question

我写了这样的代码

SELECT * FROM TestTable

这会以垂直视图获取输出。

ID | Name
1  | John
2  | Mckensy
3  | Valneech
4  | Zeebra

但是，我需要水平显示它。

1    | 2       | 3        | 4
John | Mckensy | Valneech | Zeebra

怎么能这样做？

Answer 1

您可以使用pivot来实现此要求。由于您还没有发布任何数据模型，我已经起草了一个粗略的逻辑。如果有效，请检查

静态

select * from your table
pivot (name for id in ([1],[2],[3],[4])) as anyrandomname

Answer 2

select (select Name from test where ID=1) as 1,
       (select Name from test where ID=2) as 2,
       (select Name from test where ID=3) as 3,
       (select Name from test where ID=4) as 4
from test
group by 1,2,3,4
