SQL 服务器将同一列的计数器分成两部分？

Question

在尝试使此查询正常工作后浪费了很多时间，我来这里寻求帮助。

我有一组数据要统计。但我想根据条件

计入 2 个单独的列

我有以下表格

CREATE TABLE [dbo].[DIM_DATUM](
[DATE_SK] [int] NULL,
[YEAR_NUMBER] [int] NULL,
[MONTH_NUMBER] [int] NULL,
[MONTH_NAME] [varchar](30) NULL,
[HOLIDAY] [varchar](27) NULL) ON [PRIMARY]


CREATE TABLE [dbo].[RIT](
[RideId] [bigint] NULL,
[DATE_SK] [int] NULL) ON [PRIMARY]

我正在尝试从查询中获取此输出

<table>
  <tr>
    <th>MONTH_NAME</th>
    <th>YEAR_NUMBER</th>
    <th>MONTH_NUMBER</th>
    <th>RidesYES</th>
    <th>RidesNO</th>
    <th>RidesALL</th>
  </tr>
  <tr>
    <td>JULY</td>
    <td>2017</td>
    <td>7</td>
    <td>100</td>
    <td>200</td>
    <td>300</td>
  </tr>
</table>

经过一段时间的搜索，我可以提出或多或少符合我预期的查询

SELECT h.HOLIDAY, h.MONTH_NAME, h.YEAR_NUMBER, h.MONTH_NUMBER,
COUNT(CASE WHEN h.HOLIDAY!= 'NO' THEN 1 END) AS RidesYES,
COUNT(CASE WHEN h.HOLIDAY= 'NO' THEN 1 END) AS RidesNO,
COUNT(*) AS RidesALL
FROM FEIT_RIT f
JOIN DIM_DATUM h ON h.DATE_SK = f.DATE_SK
GROUP BY h.HOLIDAY, h.MONTH_NAME, h.YEAR_NUMBER, h.MONTH_NUMBER
ORDER BY h.YEAR_NUMBER, h.MONTH_NUMBER

但这给了我以下结果： Image of query output

所以基本上，我希望在按月或年分组时将前 2 行的两个结果放在一行中。这可能吗？这可能与事务甚至子查询有关吗？如果是这样，请帮帮我！提前谢谢你

您似乎不需要 holiday 列。并按 year - month 分组，先按年再按月分组。

SELECT h.MONTH_NAME,  h.YEAR_NUMBER, h.MONTH_NUMBER,
COUNT(CASE WHEN h.PUBLIEKE_FEESTDAG != 'NO' THEN 1 END) AS RidesYES,
COUNT(CASE WHEN h.PUBLIEKE_FEESTDAG = 'NO' THEN 1 END) AS RidesNO,
COUNT(*) AS RidesALL
FROM FEIT_RIT f
JOIN DIM_DATUM h ON h.DATE_SK = f.DATE_SK
GROUP BY h.YEAR_NUMBER,  h.MONTH_NAME,  h.MONTH_NUMBER
ORDER BY h.YEAR_NUMBER, h.MONTH_NUMBER

SQL 服务器将同一列的计数器分成两部分？

SQL Server split counter into 2 parts for same column?
