Error Code: 1055 incompatible with sql_mode=only_full_group_by

问题:

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?

回答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.

The accepted solution above didn't work for me on version 5.7.9, for osx10.9 (x86_64).

Then the following worked -

set global sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
