如何使用TIME_FORMAT從SQL數據庫將HH：MM：SS轉換爲H：SS AM/PM

這是查詢的工作版本。我只需要用AS保存新的價值。感謝你給安迪。如何使用TIME_FORMAT從SQL數據庫將HH：MM：SS轉換爲H：SS AM/PM

$Wednesday = mysqli_query($conn, "SELECT *,TIME_FORMAT(class_start,'%l:%i %p') AS new_class_start,TIME_FORMAT(class_end,'%l:%i %p') AS new_class_end 
FROM wednesday INNER JOIN classes_new ON wednesday.classes_id=classes_new.classes_id WHERE classes_status='0' AND class_start NOT LIKE ''ORDER BY class_start;");

我有兩個數據類型TIME列的表，當我運行下面的時間值對查詢返回爲hh：mm：ss的。我想將其轉換爲h：mm AMPM。我曾嘗試使用JavaScript，但我相信這是可能的在MySQL中。我試圖使用TIME_FORMAT，但我認爲我得到了錯誤的語法。在下面的查詢運行後，值在while循環中回顯。請提供轉換時間值的最佳方法。謝謝！

$Wednesday = mysqli_query($conn, "SELECT *,TIME_FORMAT(wednesday.class_start,'%h:%i %p')

從週三INNER JOIN classes_new ON wednesday.classes_id = classes_new.classes_id WHERE classes_status = '0' 和class_start NOT LIKE '' ORDER BY class_start;「）;

工作版本的查詢：$週三= mysqli_query（$康恩，「SELEC T *，TIME_FORMAT（class_start，'％1：％i％p'）AS new_class_start，TIME_FORMAT（class_end，'％l：％i％p'）AS new_class_end FROM wednesday INNER JOIN classes_new ON wednesday.classes_id = classes_new.classes_id WHERE classes_status ='0'AND class_start NOT LIKE''ORDER BY class_start;「）; –

這應該工作

TIME_FORMAT(your_time,"%h:%i %p") AS your_time_formatted;

我曾嘗試使用該函數：$ Wednesday = mysqli_query（$ conn，「SELECT * DATE_FORMAT（your-date，」％h：％i％p「） FROM wednesday INNER JOIN classes_new ON wednesday.classes_id = classes_new .classes_id WHERE classes_status ='0'AND class_start NOT LIKE''ORDER BY class_start;「）;但查詢不會運行，我可以問問我哪裏出錯了？ –

看到我編輯的答案，你應該使用TIME_FORMAT。但是，你用數據庫中的實際列名取代了「你的日期」嗎？並且在SELECT * – Andy

後，您也在該查詢中缺少逗號符號，我確實將其替換爲... *和TIME_FORMAT之間是否缺少逗號？如果是的話，我已經糾正它 –
