查找查询故障之间的差异？

Question

我有一系列查询，由于某种原因，当我做最后一个查询时，它会将该字段中的所有名称切换为数字，这些数字不是其表中的键或任何我可以理解的键。我发现查询之间的差异，然后将它们合并在一起以查看两组之间的差异总量。

 SELECT [MD/SA].[MD/SA Number], Junction.[Part Number], Junction.Quantity, 
 Junction.Designator
 FROM [MD/SA] INNER JOIN Junction ON [MD/SA].ID = Junction.[MD/SA Number]
 WHERE ((([MD/SA].[MD/SA Number])=[Insert Number 1:]));

Dif1 ^

 SELECT [MD/SA].[MD/SA Number], Junction.[Part Number], Junction.Quantity, 
 Junction.Designator
 FROM [MD/SA] INNER JOIN Junction ON [MD/SA].ID = Junction.[MD/SA Number]
 WHERE ((([MD/SA].[MD/SA Number])=[Insert Number 2:]));

Dif2 ^

 SELECT Dif1.[MD/SA Number], Dif1.[Part Number], Dif1.Quantity, 
 Dif1.Designator
 FROM Dif1 LEFT JOIN Dif2 ON Dif1.[Part Number] = Dif2.[Part Number]
 WHERE (((Dif2.[Part Number]) Is Null));

我希望输出的零件号标题下有实际的零件号，而我得到的编号却没有出现在数据库中的任何地方。
