mysql启动报错:com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Expression #5 of SELECT list is not in GROUP BY clause and contains nonaggregated column ‘crm9.ccb.type_id’ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
解决方法:
在myslq配置文件my.cnf或my.ini中设置:
[mysqld]
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
注意不要带空格,不要包含”NO_AUTO_CREATE_USER“,这一项已在mysql8中去除,否则会报出如下错误:
[ERROR] [MY-000077] [Server] /usr/sbin/mysqld: Error while setting value ‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION’ to ‘sql_mode’.
/usr/sbin/mysqld: Error while setting value ‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION’ to ‘sql_mode’.
