在MySQL中按day_of_week排序 [英] Order by day_of_week in MySQL

问题描述

如何按包含星期几名称的varchar列排序mysql结果?

How can I order the mysql result by varchar column that contains day of week name?

请注意，MONDAY应该排在第一位，而不是SUNDAY.

Note that MONDAY should goes first, not SUNDAY.

推荐答案

要么按照Williham Totland的建议重新设计列，要么进行一些字符串解析以获取日期表示形式.

Either redesign the column as suggested by Williham Totland, or do some string parsing to get a date representation.

如果仅 列包含星期几，则可以执行以下操作:

If the column only contains the day of week, then you could do this:

ORDER BY FIELD(<fieldname>, 'MONDAY', 'TUESDAY', 'WEDNESDAY', 'THURSDAY', 'FRIDAY', 'SATURDAY', 'SUNDAY');
