我试图根据这两个表生成一个报告。所以我使用了这个查询，但是它没有给我想要的输出

SELECT strftime('%Y', TRANS1) AS Year, strftime('%m', TRANS1) AS Month, COUNT(*) AS Incidents, (SELECT COUNT(COUNTYNUM) FROM points WHERE dispatch.COUNTYNUM = points.COUNTYNUM) AS Zero FROM dispatch WHERE FDID = 26 GROUP BY Year, Month;

我要

Year  Month  Incidents  Zero
2016  12     3          0
2017  01     4          8

当我做这个查询时

SELECT ID, FDID, COUNTYNUM, TRANS1, (SELECT COUNT(*) FROM points WHERE points.COUNTYNUM = dispatch.COUNTYNUM) AS Zero FROM dispatch WHERE FDID = 26 AND Zero = 0;

我得到了正确的结果

ID      FDID  COUNTYNUM     TRANS1                         Zero
470640  26    201612310031  2016-12-31T00:31:34.747-05:00  0
470670  26    201612311136  2016-12-31T11:36:33.323-05:00  0
470688  26    201612311332  2016-12-31T13:32:09.940-05:00  0

这是正确的，但这意味着上一个查询应该返回此表

Year  Month  Incidents  Zero
2016  12     4          1
2017  01     3          0

因为

COUNTYNUM

201612311929

不在结果集中

我不确定我现在是否理解了这一点。Rubby ducky在这个盒子里调试实际上让我更加困惑。主要是因为我给出的示例数据集产生的结果与实际生产数据集的结果不同。如果有人知道我想做什么，我将非常感谢您的帮助。

以下是您查询的相关部分：

SELECT ...,
       (SELECT ... WHERE ... = dispatch.COUNTYNUM)
FROM dispatch
GROUP BY Year, Month;
