案例语句出现在同一行SQL Server上

im在查询方面遇到了真正的困难。

当前查询是

SELECT 
min(ID),
Date, 
CASE WHEN (ID) = '111' then SUM(Column1) END AS [Outcome1],
CASE WHEN (ID) = '222' then SUM(Column1) END AS [Outcome2],
CASE WHEN (ID) = '333' then SUM(Column1) END AS [Outcome3],
CASE WHEN (ID) = '444' then SUM(Column1) END AS [Outcome4]
FROM Table1
GROUP BY ID, Date

，结果产生

|  ID |     Date | Outcome1 | Outcome2 | Outcome3 | Outcome4 |
|-----|----------|----------|----------|----------|----------|
| 111 | 01/01/18 |       20 |   (null) |   (null) |   (null) |
| 222 | 01/01/18 |   (null) |       20 |   (null) |   (null) |
| 333 | 01/01/18 |   (null) |   (null) |       20 |   (null) |
| 444 | 01/01/18 |   (null) |   (null) |   (null) |       20 |

但是，我正在寻找的结果是

|  ID |     Date | Outcome1 | Outcome2 | Outcome3 | Outcome4 |
|-----|----------|----------|----------|----------|----------|
| 111 | 01/01/18 |       20 |       20 |       20 |       20 |

我尝试了分组，但最终以80的刚刚结果1的结果。但是我正在寻找可以用4个结果列显示的结果。

有人可以帮我吗？谢谢
