MSAccess

Question

我在MS Access中编写了一个查询，当我尝试运行此查询时出现错误。我无法找到问题所在。

SELECT 
p.[ID] as [ID],
 p.[Code] as [CODE],
p.[DESCRIPTION] as [DESCRIPTION],
p.[Coloring] as [Coloring],
 p.[Sizing] as [Sizing],
p.[BarCode] as [Barcode],
p.[PartsNo] as [PartsNo],
p.[HSN_SAC] as [HSN_SAC],
p.[GSTRate] as [GSTRate],
p.[Remarks] as Remarks,
c.[CODE] as [CategoryCode],
c.[Description] as [CategoryDescription],
b.[CODE] as [BrandCode],
b.[Description] as [BrandDescription],
s.[Id] as [SupplierId],
s.[Code] as [SupplierCode],
s.[Description] as [SupplierDescription] 
FROM [PRODUCTMASTER] p LEFT JOIN [CATEGORYMASTER] c on p.[CategoryId] = c.[ID] 
LEFT JOIN [BRANDMASTER ] b on p.[BrandId] =  b.[ID] 
LEFT JOIN [SUPPLIERAMSTER] s on p.[SupplierId] =  s.[ID]

Answer 1

当您链接两个以上的表时，需要括号：

FROM (([PRODUCTMASTER] p LEFT JOIN [CATEGORYMASTER] c on p.[CategoryId] = c.[ID]) 
LEFT JOIN [BRANDMASTER ] b on p.[BrandId] =  b.[ID]) 
LEFT JOIN [SUPPLIERAMSTER] s on p.[SupplierId] =  s.[ID]

我建议使用查询编译器构建SQL查询，它比手动更容易，你不会像这样拼错错误和包围错误。再次检查[BRANDMASTER ]之后的空格，这在任何情况下都是不好的做法。从表定义中的列名中删除尾随空格，可能会导致其他奇怪的错误。
