Question

我想获得标题状态，列出选定日期范围内每天所有用户的第一次和最后一次刷卡时间的列表（可由用户选择）。现在，每次用户滑动时我都会返回。

当您似乎想要简单的聚合时，为什么要使用窗口函数？

<wj-flex-grid-column *ngFor="let col of columnDefinitions" 
[minWidth]="200" width="*"
[header]="col.header" [binding]="col.binding" [visible]="col.visible" 
[allowDragging]="false" [wordWrap]="true" >
 </wj-flex-grid-column>

我将SELECT u.[FirstName] + ' ' + u.[LastName] AS EmployeeName min(e.LoggedTime) as first max(e.LoggedTime) as last FROM [ProtegeGX].[dbo].[Users] u JOIN [ProtegeGXEvents].[dbo].[Events] e ON e.RecordIndex1 = u.UserID JOIN [ProtegeGX].[dbo].[EventTypes] et on e.EventTypeID = et.EventTypeID WHERE e.LoggedTime Between '2019-05-29' AND '2019-05-31' AND u.userid = 97 GROUP BY u.[FirstName] + ' ' + u.[LastName];更改为内部联接，因为JOIN子句仍然限制了它们。

如果您想每天这样做，

WHERE
