Aggregated query without GROUP BY

Question

This query seems to work perfect on my older machine. However, on my new machine with MySQL 5.7.14 and PHP 5.6.25 it seems to throw an error:

Fatal er

Answer 1

A change was made in version 5.7-ish where it will now, by default, reject queries in which you aggregate using a function (sum, avg, max, etc.) in the SELECT clause and fail to put the non-aggregated fields in the GROUP BY clause. This behavior is part and parcel to every other RDBMS and MySQL is finally jumping on board.

You have two options:

1. You can change the MySQL settings to default to the old behavior to allow not-so-great queries like this. Information can be found here
2. You can fix your query

Option 2 would look something like:

SELECT id, password, COUNT(id) AS count FROM users WHERE email = :email GROUP BY id, password LIMIT 1

Answer 2

Change ur SQL mode to default.. it will execute without error The SQL mode defines the syntax of the query. If you using ONLY_FULLY_GROUPBY you have to write a query with group by for all aggregator functions

Answer 3

Its a little late but I just ran into this error.

This command might be useful for anyone else who runs into the same error

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

More information about this can be found at Table Plus and other links quoted above by JNevill.

Hope it helps someone else.

Answer 4

Easiest answer, in config/database.php make sure to set strict => true to strict => false for the mysql settings.

This will allow for less than strict queries at a cost of security for normal well-formed sql calls (still not 100% secure), but will allow for the use of other sql calls that could be in-secure if written improperly.
