关于多表相联时当表未审核时不显示的问题
SELECT   Pi.PiNO,   Pi.Date,   Pi.InureDate,   InCase.Date   AS   DeliveryDate,   Pi.Amount,  
            PayMent.PayMentName,   OrderProfilt.Date   AS   Expr1,   OrderProfilt.Rate,  
            Pi.Amount   *   OrderProfilt.GrossRate   AS   SumGross,   OrderProfilt.GrossRate
FROM   OrderProfilt   RIGHT   OUTER   JOIN
            Pi   ON   OrderProfilt.PiNO   =   Pi.PiNO   LEFT   OUTER   JOIN
            PayMent   ON   Pi.PayMentID   =   PayMent.PayMentID   LEFT   OUTER   JOIN
            InCase   ON   Pi.PiNO   =   InCase.PINO
WHERE   (1   =   1)   AND   (OrderProfilt.IsAuditing   =   1)   AND   (InCase.IsAuditing   =   1)
这条语句当incase   和orderprofilt的isauditing=0时,连pi都不能显示了,我是想incase和orderprofilt未审核时,只显示pi的表不显示他们的表  
除了用case语句验证外,有没有办法让这两个表做完自身筛选再绑定

------解决方案--------------------
WHERE (1 = 1)
不能去掉吗??
