Com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Expression # 2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'col_user_6.a.START_TIME' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

Solution: execute SET GLOBAL sql_mode =''; change sql_mode to non-only_full_group_by mode. Verify that SELECT @ @ GLOBAL.sql_mode or SELECT @ @ sql_mode is in effect

SET sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'
