该视图的sql语句如下：
- SQL code
SELECT mb.MBID, m.MName, t.TName, c.CName, mb.SerialNum, mb.State, mb.DeliveryNum, CONVERT(varchar(100), mb.SendDate, 23) AS SendDate, CONVERT(varchar(100), mb.BackDate, 23) AS BackDate, mb.RemarkFROM dbo.MachineBroken AS mb INNER JOIN dbo.Machine AS m ON mb.MBID = m.MID INNER JOIN dbo.Type AS t ON m.TID = t.TID INNER JOIN dbo.Class AS c ON t.CID = c.CIDWHERE (mb.IsBack = 0)
单独运行该视图的时候没有数据显示(表中所有数据的IsBack列值都为True，该列类型为bit)，但从视图中获取数据时(运行“select * from View_MachineBrokenDetail”)却有数据显示，这是什么原因呢？

- SQL code
SELECT mb.MBID, m.MName, t.TName, c.CName, mb.SerialNum, mb.State, mb.DeliveryNum, CONVERT(varchar(100), mb.SendDate, 23) AS SendDate, CONVERT(varchar(100), mb.BackDate, 23) AS BackDate, mb.RemarkFROM dbo.MachineBroken AS mb INNER JOIN dbo.Machine AS m ON mb.MBID = m.MID INNER JOIN dbo.Type AS t ON mb.TID = t.TID INNER JOIN dbo.Class AS c ON mb.CID = c.CIDWHERE (mb.IsBack = 0)try感觉你的关联有问题，你还是一个表一个表的理清了吧
