MySQL on order on varchar

Question

在我的表中，有一个名为time的列。

字段类型为varchar，值类似于HH：MM，02-25,21-42,07-15

如何通过desc进行排序？

Answer 1

select * from table_name order by column_name DESC;

其中，

table_name is name of table and 
column_name is name of column in the table (independent of whatever the data-type)

注意： - for proper o/p Your datatype for the time column should be datetime

Answer 2

问题由以下方法解决：

ORDER BY CreationDate ASC,CreationTime DESC
