Question

我正在调试以下代码并获得异常：查询表达式中的语法错误（缺少运算符）＆quot; data1.PS NO = data2.PS N＆＃39;。

代码是：

        If data1 Is Nothing And data2 Is Nothing Then
            MsgBox("Open two excel files to generate report", MsgBoxStyle.Information, "Try Again")
       Else
           cntcn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 8.0;HDR=YES'"
        oleConnection = New System.Data.OleDb.OleDbConnection(cntcn)

        oleCommand = New System.Data.OleDb.OleDbDataAdapter("SELECT May FROM [data1] INNER JOIN [data2] ON data1.PS NO=data2.PS NO WHERE data1.Month = 'May'", oleConnection)

        oleCommand.Fill(data3)

    End If

这里我创建了两个数据表data1和data2并应用了内连接查询。但是得到了上述异常请帮忙。提前谢谢。

Answer 1

   oleCommand = New System.Data.OleDb.OleDbDataAdapter("SELECT data1.Month FROM [data1] INNER JOIN [data2] ON data1.[PS NO]=data2.[PS NO] WHERE data1.Month = 'May'", oleConnection)

问题：

您：SELECT May更改为data1.[Month]
将此更改为data1.PS NO：data1.[PS NO]

在两个数据表
