mysql - Error Code: 1055 incompatible with sql_mode=only_full_group_by

Question

I have been having issues switching to an offline version of the Lahman SQL baseball database. I was using a terminal embed into an EDX course. This command runs fine on the web terminal:

SELECT concat(m.nameFirst,concat(" ",m.nameLast)) as Player,
    p.IPOuts/3 as IP,
    p.W,p.L,p.H,p.BB,p.ER,p.SV,p.SO as K,
    p.IPOuts+p.W*5+p.SV+p.SO-p.BB-p.L-p.H as PTS,
    p.yearID as Year
FROM Pitching p
Inner Join Master m
    ON p.playerID=m.playerID
WHERE p.yearID=2014 AND p.IPOuts>=50
GROUP BY m.playerID
ORDER BY PTS DESC;

Which is running SQL 5.5.46, but when I use my offline version running 5.7.10 I get the following error code:

Error Code: 1055. Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'stats.m.nameFirst' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

I've been reading a lot of solutions to people's problems, but they haven't helped in this case. That's never happened before, so I think this is either super obvious or maybe I'm getting ok at coding. Anyway, anyone know how to fix this?

Answer 1

In 5.7 the sqlmode is set by default to:

 ONLY_FULL_GROUP_BY,NO_AUTO_CREATE_USER,STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION

To remove the clause ONLY_FULL_GROUP_BY you can do this:

SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

This supposed you need to make that GROUP BY with non aggregated columns.
