Question

我有下表CampaingControl：

+----------------+-----+-------------+--------------+-----------+--------+
| id_vehicleCamp | vin | id_campaign | id_workorder | id_client | status |
+----------------+-----+-------------+--------------+-----------+--------+
|                |     |             |              |           |        |
+----------------+-----+-------------+--------------+-----------+--------+
|                |     |             |              |           |        |
+----------------+-----+-------------+--------------+-----------+--------+

status列只有两个值 APPLIED 或 PENDING 。

我需要做的是显示distinct列中的所有id_campaign值，其中一个或多个status值等于待定

例如，我在表格中有这些数据：

+----------------+-------+-------------+--------------+-----------+---------+
| id_vehicleCamp |  vin  | id_campaign | id_workorder | id_client |  status |
+----------------+-------+-------------+--------------+-----------+---------+
|        1       | 43006 |      1      |   OT-001-16  |    NULL   | PENDING |
+----------------+-------+-------------+--------------+-----------+---------+
|        2       | 43010 |      1      |   OT-002-16  |     2     | PENDING |
+----------------+-------+-------------+--------------+-----------+---------+
|        3       | 43009 |      1      |   OT-002-16  |    NULL   | APPLIED |
+----------------+-------+-------------+--------------+-----------+---------+
|        4       | 43008 |      2      |   OT-002-16  |    NULL   | APPLIED |
+----------------+-------+-------------+--------------+-----------+---------+
|        5       | 43002 |      3      |   OT-005-16  |     4     | PENDING |
+----------------+-------+-------------+--------------+-----------+---------+

最终输出必须是：

+-------------------+
| Pending Campaings |
+-------------------+
|         1         |
+-------------------+
|         3         |
+-------------------+

值1的活动有一个 APPLIED status，但2有 PENDING status，然后没有完成。

价值3的活动只有一条记录并且待处理 status，然后没有完成。

Answer 1

SELECT id_campaign AS [Pending Campaings] FROM CampaingControl
WHERE status = 'PENDING' GROUP BY id_campaign HAVING COUNT(*) >= 1

OR

SELECT DISTINCT id_campaign AS [Pending Campaings] FROM CampaingControl
WHERE status = 'PENDING'

Answer 2

使用条件聚合：

SELECT id_campaign
FROM CampaingControl
GROUP BY id_campaign
HAVING SUM(CASE WHEN status = 'PENDING' THEN 1 ELSE 0 END) >= 1

请注意，此查询会推广到您可能遇到的其他问题，例如有多少个广告系列有两个待处理条目但只有一个已应用条目。

Answer 3

它也应该有效：

SELECT id_campaign FROM TABLE_NAME WHERE status = 'PENDING' GROUP BY  id_campaign

Answer 4

您可以将查询用作

SELECT id_vehicleCamp FROM TABLE_NAME WHERE id_vehicleCamp IN 
(SELECT DISTINCT STATUS FROM TABLE_NAME);

此查询提供您的结果。

仅选择SQL Server中具有一个或多个特定值的值
