Question

我的SQL分组按周查询如下所示，但是我得到了以下错误。

列'timesheet.timesheet_date'在选择列表中无效，因为它不包含在聚合函数或GROUP BY子句中。

在这方面有人可以帮助我

我的查询：

select 
   DatePart(week, timesheet_date),
   count(timesheet.timesheet_id) as TimeSheetID,
   timesheet.timesheet_date,
   timesheet.start_time,
   timesheet.end_time, 
   timesheet.timesheet_status_id,
   timesheet.is_deleted,
   timesheet.created_by,
   timesheet.modified_by,
   timesheet.created_date,
   task.name,
   project.name,
   [user].first_name, [user].last_name 
from 
   timesheet, task, project, [user] 
where 
   task_id = (select task_id from project_task 
              where project_task_id = timesheet.project_task_id) 
   and project_id = (select project_id from project_task 
                     where project_task_id = timesheet.project_task_id) 
   and [user].user_id = timesheet.user_id 
   and timesheet.user_id = 30 
group by 
   timesheet.timesheet_id

Answer 1

从异常消息中，我将假设SQL Server。

对于聚合（SUM / MAX / MIN / COUNT），您需要包括GROUP BY中不属于聚合的所有列。

因此，对于您的查询，您将拥有类似

的内容

select  DatePart(week, timesheet_date),
        count(timesheet.timesheet_id) as TimeSheetID,
        timesheet.timesheet_date,
        timesheet.start_time,
        timesheet.end_time,
        timesheet.timesheet_status_id,
        timesheet.is_deleted,
        timesheet.created_by,
        timesheet.modified_by,
        timesheet.created_date,
        task.name,
        project.name,
        [user].first_name,
        [user].last_name 
from    timesheet,
        task,
        project,
        [user] 
where   task_id = (select task_id from project_task where project_task_id=timesheet.project_task_id) 
and project_id = (select project_id from project_task where project_task_id=timesheet.project_task_id) 
and [user].user_id = timesheet.user_id 
and timesheet.user_id =30 
group by    DatePart(week, timesheet_date),
            timesheet.timesheet_date,
            timesheet.start_time,
            timesheet.end_time,
            timesheet.timesheet_status_id,
            timesheet.is_deleted,
            timesheet.created_by,
            timesheet.modified_by,
            timesheet.created_date,
            task.name,
            project.name,
            [user].first_name,
            [user].last_name

Answer 2

试试这个：

select  DatePart(week, timesheet_date),
        count(timesheet.timesheet_id) as TimeSheetID,
        timesheet.timesheet_date,
        timesheet.start_time,
        timesheet.end_time,
        timesheet.timesheet_status_id,
        timesheet.is_deleted,
        timesheet.created_by,
        timesheet.modified_by,
        timesheet.created_date,
        task.name,
        project.name,
        [user].first_name,
        [user].last_name 
from    timesheet,
        task,
        project,
        [user] 
where   task_id = (select task_id from project_task where project_task_id = timesheet.project_task_id) 
and project_id = (select project_id from project_task where project_task_id = timesheet.project_task_id) 
and [user].user_id = timesheet.user_id 
and timesheet.user_id =30 
group by timesheet.timesheet_id,
        timesheet.timesheet_date;
