php - 如何转换 HH :MM:SS to H:SS AM/PM from SQL database with TIME_FORMAT

Question

这是查询的工作版本。我只需要用 AS 保存新值。谢谢 Andy。

$Wednesday = mysqli_query($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;");

当我在下面运行查询时，我有一个包含两个数据类型 TIME 列的表，时间值返回为 hh:mm:ss 。我想将它转换为 h:mm AMPM。我尝试过使用 javascript，但我确信这在 MySQL 中是可行的。我曾尝试使用 TIME_FORMAT，但我认为我的语法有误。运行以下查询后，值将在 while 循环中回显。请就转换时间值的最佳方法提出建议。谢谢!

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

从星期三内部加入 classes_new ON wednesday.classes_id=classes_new.classes_id WHERE classes_status='0' AND class_start NOT LIKE ''ORDER BY class_start;");

Answer 1

这应该可行

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