其摘要是您可以使用Select b.Id as BatchId, b.CourseId as CourseId, b.BatchNumber as BatchNumber, b.BatchTimingsFrom as BatchTimingsFrom, b.BatchTimingsTo as BatchTimingsTo, b.BatchDuration as Duration, b.BatchDate as BatchDate, b."Days" as "Days", b.CourseRoomId as CourseRoomId, c.CourseName as CourseName, cr.RoomName as RoomName, cr.RoomCapacity as RoomCapacity ,COUNT(*) OVER (PARTITION BY b.Id) countstudentinBatches from dbo."Batches" b INNER JOIN dbo.Courses c ON b.CourseId = c.Id INNER JOIN dbo.CourseRooms cr ON b.CourseRoomId = cr.Id INNER JOIN dbo.StudentBatchRelation sr ON sr.BatchId = b.Id WHERE b.ActiveBatch = 1 个事件。当然，您可以手动并独立于数据库来管理情境。您必须将时间存储在错误的密码上，然后将当前时间与存储的时间进行比较。
