OpenPNE3 Plugins » opRankingPlugin

Overview (概要)¶

MySQL 5.7 の Strict Mode が有効な状態での動作確認 (#4033) を行った際に発生した。

アクセス数ランキング画面を開くと下記のエラーが発生する:

SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'openpne.a.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

Causes (原因)¶

SELECT a.id AS a__id, a.member_id_to AS a__member_id_to, COUNT(*) AS a__0
  FROM ashiato a
 WHERE (a.created_at >= '2017-02-15' AND a.created_at < '2017-02-16')
 GROUP BY a.member_id_to
 ORDER BY COUNT(*) DESC
 LIMIT 10

上記のクエリで、a.id が GROUP BY に含まれていないためエラーが発生している。
