1、Err1055,出現這個問題往往是在執行sql語句時候,在最后一行會出現這個問題。
[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column
'information_schema.PROFILING.SEQ' which is not functionally dependent on columns in GROUP BY clause;
this is incompatible with sql_mode=only_full_group_by
解決方法:
在 /etc/my.cnf 文件里加上如下:
sql_mode='NO_ENGINE_SUBSTITUTION'
然后,重啟Mysql服務就可以解決了!
也可以 用 any_value() 方法解決
