Re: Reverting SQL Standard to SQL-92

I don't think you get my Problem. I will repeat it for clarity.
Prior to upgrading Mysql to 5.7 ,we used Mysql 5.5 which has also has sql_mode='only_full_group_by'. This worked seamlessly.
After upgrading to Mysql 5.7 the "only_full_group_by" mode which follows SQL-Standard 99 started allowing queries that failed in Mysql5.5
SELECT a.sno,b.sno,,b.location
FROM Name AS a
JOIN Location AS b ON a.sno=b.sno
GROUP BY a.sno,b.location

This would fail in Mysql 5.5 (or) 5.6, but will get executed properly in Mysql 5.7.
We want group by to work the same along all editions, so any way to revert it back to way it worked in Mysql 5.5 [We are setting the sql_mode - "only_full_group_by"]?
