Laravel-在phpmyadmin上使用结果的查询分组错误

Question

The query is:

$last_topics = Topics::orderby('date', 'DESC')->groupBy('section')->get();

And error:

so on error we can see query is: select * from topics group by section order by date desc

But as you can see The same query in phpMyAdmin works great, and I have my result

So what's wrong?

I addition I can say that without groupBy in this query inside Laravel doesn't alert error, like: $last_topics = Topics::orderby('date', 'DESC')->get();

But as I said in phpmyadmin the same query with groupby works great

Answer 1

OK this the mode in which your database is being used within your database config /config/database.php . Laravel is not adding all the columns to group by.

'connections' => [
        'mysql' => [
            // Will work for you
            'strict' => false,

            // wont work for you
            'strict' => true,
        ]
    ]

Answer 2

您可以在get后致电groupBy ：

Topics::orderby('date', 'DESC')->get()->groupBy('section');
