将nvarchar值'00000000-0000-0000-0000-000000000000'转换为数据类型int时转换失败

Question

我有一个查询正在比较表中的uniqueidentifier和它的奇怪的一个。

SELECT *  FROM   vw_ryzex_CustomerAssets where BillToId='51ee47d2-eb97-4b12-8865-dab9a7f15a46'

因此，当我运行此查询时，我收到以下错误 将nvarchar值'00000000-0000-0000-0000-000000000000'转换为数据类型int。

时转换失败

但是当我只选择前1000名时我得到的结果并没有发生错误我尝试了Casting并转换检查nulls我可以尝试跟随查询但是没有工作

SELECT * FROM   vw_ryzex_CustomerAssets_V2 where CAST(BillToId as nvarchar(200))=Cast('51ee47d2-eb97-4b12-8865-dab9a7f15a46' as nvarchar(200))

SELECT * FROM   vw_ryzex_CustomerAssets where (Case BillToId 
                                                when '00000000-0000-0000-0000-000000000000' Then NEWID()
                                       ELSE BillToId
                                                END) = '51ee47d2-eb97-4b12-8865-dab9a7f15a46'

有人可以帮我这个吗？？

这是视图定义

来自ryzex_CustomerAsset tbl的BillToId是一个非null uniqueidentifier
