多部分标识符＆＃39; dbo.AdditionalInfo.UserDefined3＆＃39;无法受约束

Question

我有这个问题:(这是因为我的select语句？还是任何join？派生表？或我的CASE语法？

出现此CASE语法时出现错误：CASE WHEN dbo.AdditionalInfo.UserDefined3 = 1 THEN 2

因为在它之前： CASE WHEN WorkOrder.DateCreated < (CASE WHEN (DATEPART(dw, dbo.ToBeScheduled_InProgress.Start) = 2) THEN (ToBeScheduled_InProgress.Start + 0.625) - 3 ELSE (ToBeScheduled_InProgress.Start + 0.625) - 1 END) THEN 1 ELSE 2 END AS ScheduleTime
