我需要OP10上的數據第一次輸入的開始時間和最後一次輸入的結束時間。(OP10開始時間:上午10點和結束時間:上午11點10分)。與明智的OP20和OP30類似。爲避免同一數據的多個報告(OP10),給我ITS啓動&結束時間就夠了。如何使用SQL中的過濾數據獲取內部連接查詢?

SQL表結果:

+---------+------------+-----------------------------+-----------------------------+ 
| Line  Operation |  StartDate    | EndDate     | 
+---------+------------+-----------------------------+-----------------------------+ 
| ACOE | OP10  | 2017-01-27 10:00:00.000  | 2017-01-27 10:10:00.000 | 
| ACOE | OP10  | 2017-01-27 11:00:00.000  | 2017-01-27 11:10:00.000 | 
| ACOE | OP20  | 2017-01-27 11:10:00.000  | 2017-01-27 11:15:00.000 | 
| ACOE | OP20  | 2017-01-27 11:20:00.000  | 2017-01-27 11:25:00.000 | 
| ACOE | OP30  | 2017-01-27 12:10:00.000  | 2017-01-27 12:15:00.000 | 
| ACOE | OP30  | 2017-01-27 12:20:00.000  | 2017-01-27 12:25:00.000 | 
+---------+------------+-----------------------------+-----------------------------+ 

需要輸出類似如下格式:

+---------+------------+-----------------------------+-----------------------------+ 
| Line  Operation |  StartDate    | EndDate     | 
+---------+------------+-----------------------------+-----------------------------+ 
| ACOE | OP10  | 2017-01-27 10:00:00.000  | 2017-01-27 11:10:00.000 | 
| ACOE | OP20  | 2017-01-27 11:10:00.000  | 2017-01-27 11:25:00.000 | 
| ACOE | OP30  | 2017-01-27 12:10:00.000  | 2017-01-27 12:25:00.000 | 
+---------+------------+-----------------------------+-----------------------------+

試試這個:

SELECT Line, Operation, StartDate = MIN(StartDate), EndDate=MAX(EndDate) 
GROUP BY Line, Operation 
ORDER BY Line, Operation

但是使用內部連接查詢這種語法StartDate = MIN(StartDate),EndDate = MAX(EndDate)拋出錯誤。 – Dhamo

sintax我寫信給你它可以...你可以發佈你的完整查詢嗎? – DarioN1
