Question

我在PHP中针对Access数据库编写SQL查询，并且我收到此错误：

＆＃34; SQLSTATE [42000]：语法错误或访问冲突：-3100 [Microsoft] [ODBC Microsoft Access驱动程序]查询表达式中的语法错误（缺少运算符）＆＃39;（FROM [Tbl_Invoice_Details]，INNER JOIN [Tbl_Product_Table] ON [Tbl_Invoice_Details.Product_ID] = [Tbl_Product_Table.Product_ID]）WHERE Invoice_ID = Pa_RaM000＆＃39;。＆＃34;

这是我的问题：

SELECT [Tbl_Invoice_Details.Product_ID], 
            [Tbl_Invoice_Details.Seed Size], [Tbl_Invoice_Details.Ref2], [Tbl_Invoice_Details.RefNo], [Tbl_Invoice_Details.Quantity Ordered],
            [Tbl_Invoice_Details.Quantity Delivered], [Tbl_Invoice_Details.PricePerUnit], [Tbl_Invoice_Details.Extended],
            [Tbl_Product_Table.Product_ID], [Tbl_Product_Table.Hybrid Brand], (FROM [Tbl_Invoice_Details] INNER JOIN [Tbl_Product_Table]
            ON [Tbl_Invoice_Details.Product_ID] = [Tbl_Product_Table.Product_ID]) WHERE Invoice_ID = ?

为什么会失败？

Answer 1

您的查询失败，因为方括号中的所有内容都被解释为单个名称，因此

SELECT [Tbl_Invoice_Details.Product_ID] ... FROM [Tbl_Invoice_Details]

与

相同

SELECT [Tbl_Invoice_Details].[Tbl_Invoice_Details.Product_ID] ... FROM [Tbl_Invoice_Details]

Access不允许我们定义包含句点的字段名称，因此永远不会起作用。

你的意思是

SELECT [Tbl_Invoice_Details].[Product_ID] ... FROM [Tbl_Invoice_Details]

是（正确的）一种表达方式

SELECT [TableName].[FieldName] ... FROM [TableName]

Answer 2

以下查询如何：

SELECT i.Product_ID, i.[Seed Size], i.Ref2, i.RefNo, i.[Quantity Ordered], 
       i.[Quantity Delivered], i.PricePerUnit, i.Extended, p.[Hybrid Brand]
FROM Tbl_Invoice_Details i
INNER JOIN Tbl_Product_Table p ON i.Product_ID = p.Product_ID
WHERE i.Invoice_ID = ?

Answer 3

确实，不需要[Tbl_Product_Table.Hybrid_Brand]之后的逗号.. 也许你的发票在锚点之间？所以
WHERE Invoice_ID = Pa_RaM000
变成了 WHERE Invoice_ID = "Pa_RaM000"

＆＃34;查询表达式中的语法错误（缺少运算符）＆＃34;来自PHP的Access查询
