MySQL question: SQL_MODE = ONLY_FULL_GROUP_BY
problem
ERROR: Expression #1 of SELECT list is not in GROUP BY clause
and contains nonaggregated column 'xxx.sd.dic_cn_name' which
is not functionally dependent on columns in GROUP BY clause;
this is incompatible with sql_mode=only_full_group_by Error
Code: 1055
the reason
From the error message, it is necessary to putxxx.sd.dic_cn_nameThe field is placed in the group BY clause.
Error SQL:
SELECT
sd.dic_cn_name as memberTypeCnName,
sd.dic_en_name as memberTypeEnName,
GROUP_CONCAT( cm.member_cn_name ) as castCnName,
GROUP_CONCAT( cm.member_en_name ) as castEnName
FROM
xxx.sn_movie_cast_members mcm,
xxx.sn_cast_members cm,
xxx.sn_system_dictionary sd
WHERE
mcm.cast_members_id = cm.id AND
sd.dic_code = mcm.member_type_code AND
mcm.movie_id = 214
GROUP BY
mcm.member_type_code;
Repaired SQL:
SELECT
sd.dic_cn_name as memberTypeCnName,
sd.dic_en_name as memberTypeEnName,
GROUP_CONCAT( cm.member_cn_name ) as castCnName,
GROUP_CONCAT( cm.member_en_name ) as castEnName
FROM
xxx.sn_movie_cast_members mcm,
xxx.sn_cast_members cm,
xxx.sn_system_dictionary sd
WHERE
mcm.cast_members_id = cm.id AND
sd.dic_code = mcm.member_type_code AND
mcm.movie_id = 214
GROUP BY
mcm.member_type_code, sd.dic_cn_name, sd.dic_en_name;
Segments that will need to adddic_cn_namewithdic_en_name, Add the group by clause, you don't need to change the MySQL configuration.
