COUNT（CASE WHEN）SQL中的重复行

Question

初学SQL用户在这里。

我需要我的桌子看起来像这样：

ModuleID | Draft | Proposed | Committed | Total
---------------------------------------------
A        |    1  |    0     |     1     | 2

目前看起来像这样：

ModuleID | Draft | Proposed | Committed | Total
---------------------------------------------
A        |    1  |    0     |     1     | 1
A        |    0  |    0     |     1     | 1

以下是代码：

SELECT T3.NAME AS ModuleID, 
   COUNT(CASE WHEN T4.LITERAL_NAME = 'Draft' THEN 1 END) AS Draft,
   COUNT(CASE WHEN T4.LITERAL_NAME = 'Proposed' THEN 1 END) AS Proposed,
   COUNT(CASE WHEN T4.LITERAL_NAME = 'Committed' THEN 1 END) AS Committed,
   SUM(1) AS Total

FROM ...
WHERE ...

GROUP BY T4.LITERAL_NAME,T3.NAME

所以它提取了正确的信息，但它每列重复模块ID。我已经仔细检查了主板和谷歌，无法弄清楚是什么问题。请帮忙！

Answer 1

GROUP BY T4.LITERAL_NAME,T3.NAME

更改为

GROUP BY T3.NAME
