оператор ошибки: ошибка: ORA-00979: не выражение GROUP BY
select org_division.name , org_department.name , org_surveylog.division_code as divisionCode,org_surveylog.department_code as departmentCode , max(org_surveylog.actiondate) from org_surveylog
left join org_division on (org_surveylog.division_code= org_division.division_code and org_surveylog.SURVEY_NUM= org_division.survey_num)
left join org_department on (org_surveylog.department_code = org_department.department_code and org_surveylog.SURVEY_NUM = org_department.survey_num)
group by org_surveylog.division_code,org_surveylog.department_code
но ниже все в порядке
select org_surveylog.division_code as divisionCode,org_surveylog.department_code as departmentCode , max(org_surveylog.actiondate) from org_surveylog
left join org_division on (org_surveylog.division_code= org_division.division_code and org_surveylog.SURVEY_NUM= org_division.survey_num)
left join org_department on (org_surveylog.department_code = org_department.department_code and org_surveylog.SURVEY_NUM = org_department.survey_num)
group by org_surveylog.division_code,org_surveylog.department_code
как использовать group by с левым соединением, когда мне нужно показать значение org_division.name, org_department.name ?
