what is the best way to call a group of results from mySQL by quarter?

Question

I am looking to order a set of results of a mySQL data by quarter. They have data fields, so I am wondering if I should be doing this in PHP or in the query itself?

Answer 1

if you have date field in the db use it to group with it,

like :

group by QUARTER(date)

of course if you want to take in account the years also

use

group by YEAR(date) , QUARTER(date)

Answer 2

You can use GROUP BY Clause in mysql query and return results as -

group by Quarter(date)

Where Quarter is a pre-defined function in mysql.

Answer 3

我会在数据库中执行此操作-查找MySQL函数Quarter（Date）。
