SELECT RIGHT(timestamp,LEN(timestamp) -12) as DailyTime, left(roundtrip, LEN(roundtrip) -2) as HalfHourDuration, site_code
FROM tblServer_Status
WHERE timestamp >= dateadd(day, datediff(day,'19000101',CURRENT_TIMESTAMP),'19000101') AND timestamp < dateadd(day, datediff(day,'19000101',CURRENT_TIMESTAMP)+1,'19000101') AND server = 'ServerName' AND site_code = 'A'
GROUP BY timestamp, roundtrip, site_code HAVING(((COUNT(site_code))>0))
ORDER BY timestamp
每個時間間隔最新值我有這樣的代碼,讓我這種輸出如何獲得在SQL Server

,但我需要得到每一次最新的時間。 喜歡這個
| DailyTime | HalfHourDuration | Site_Code|
12:00AM 242 A
12:30AM 462 A
01:00AM 322 A
01:30AM 116 A
02:00AM 121 A
02:30AM 111 A
就是這樣的。 任何人都可以幫助我配置我的代碼。
謝謝。
夥計。謝謝。但時間的順序是按數字。你能幫我把它按AM - PM排序。 – Elphrian
我需要從12:00 AM到11:30 PM的時間排序。感謝您的答覆。 – Elphrian
