Question

我正在尝试制作一些代码，如果该项已经存在则会更新一行。它看起来像这样：

updateStr = "UPDATE platinum_paste SET ([aluminium], [calcium], [chrome], [iron], [lead], [silicon], [zirconium]) VALUES (" & aluminium & "," & _
                                                                                                                              calcium & "," & _
                                                                                                                              chrome & "," & _
                                                                                                                              iron & "," & _
                                                                                                                              lead & "," & _
                                                                                                                              silicon & "," & _
                                                                                                                              zirconium & _
                                                                                                                              ") WHERE [lot_number] = " & lotNumber

Debug.Print updateStr

If MsgBox("Item already exists. Do you want to update its details?", vbYesNo) = vbYes Then
            objMyConn.Execute updateStr, dbFailOnError

Else
            'Do nothing

End If

当我尝试运行它时，单击＆＃34;是＆＃34;在MsgBox中将导致错误：

自动化错误

谁能告诉我我做错了什么？我试图添加我能想到的所有可能的调试功能。数据库连接适用于SELECT和INSERT。这是我的INSERT字符串，它可以正常工作：

insertStr = "INSERT INTO platinum_paste ([lot_number], [aluminium], [calcium], [chrome], [iron], [lead], [silicon], [zirconium]) VALUES (" & lotNumber & "," & _
                                                                                                                                                 aluminium & "," & _
                                                                                                                                                 calcium & "," & _
                                                                                                                                                 chrome & "," & _
                                                                                                                                                 iron & "," & _
                                                                                                                                                 lead & "," & _
                                                                                                                                                 silicon & "," & _

UPDATE - 字符串的语法错误。你需要写

 UPDATE table_name
 SET column1=value1,column2=value2,...
 WHERE some_column=some_value;
