+-----------+-----------------+-----------+----------+---------------+
|         1 | Mr.A            | Tom       |        1 |            20 |
|         1 | Mr.A            | Tom       |        2 |            20 |
|         1 | Mr.A            | Tom       |        3 |            10 |
|         1 | Mr.A            | Harry     |        1 |            20 |

我想创建一个类似于此的ssrs报告。我正在使用2012版本。实际小时数是每个项目的工作时间总和。

 +------------+-----------------+----------------+--------------+
| Project ID | Project Manager | Approved Hours | Actual Hours |
+------------+-----------------+----------------+--------------+
|          1 | Mr.A            |            120 |          110 |
|          2 | Mr.B            |            100 |           85 |
+------------+-----------------+----------------+--------------+

我是SQL的新手，我可以通过一次查询完成这项工作。

Answer 1

正如@jarlh建议只需做INNER JOIN＆amp; group by如下：

SELECT T.[Project ID],
       T.[Project Manager],
       T.[Approved Hours],
       SUM(T1.[Working Hours]) [Actual Hours]
FROM Table1 T
     INNER JOIN Table2 T1 ON T.[Project ID] = T1.[Project ID]
GROUP BY T.[Project ID],
         T.[Project Manager],
         T.[Approved Hours];

结果：

+------------+-----------------+----------------+--------------+
| Project ID | Project Manager | Approved Hours | Actual Hours |
+------------+-----------------+----------------+--------------+
|          1 | Mr.A            |            120 |          110 |
|          2 | Mr.B            |            100 |           85 |
+------------+-----------------+----------------+--------------+
