GROUP_CONCAT change GROUP BY order

Question

I have a VIEW (lots of joins) that outputs data ordered by a date ASC. Works as expected.

OUTPUT similar to:

ID date         tag         


        

Answer 1

How about ordering your GROUP_CONCAT?

SELECT value1, GROUP_CONCAT(value1 ORDER BY date DESC)   
FROM table1  
GROUP BY value1;

That's the syntax you need a presume.
