Vb.net問題更新數據庫

Question

我的問題發生在da.Update（dt）。我收到「OleDbException was unhandled，INSERT INTO語句中的語法錯誤」錯誤。它工作時，我用一個沒有字段名稱和只有10列的基本表，但現在我有25個項目不起作用。

Dim dt As New DataTable 
    Dim ds As New DataSet 

    con.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source= C:\TPComplete.accdb;Persist Security Info=False;" 

    con.Open() 
    MsgBox("here") 
    ds.Tables.Add(dt) 

    Dim da As New OleDbDataAdapter 

    da = New OleDbDataAdapter("SELECT * FROM DReview", con) 

    da.Fill(dt) 



    Dim newRow As DataRow = dt.NewRow 

    newRow.Item("Caller") = Caller 
    newRow.Item("Associate Name") = Associate 
    newRow.Item("Store Number") = "1" 
    newRow.Item("Number of Rings") = Ring 
    newRow.Item("Time on Hold") = HoldTime 
    newRow.Item("Greeting: 3 or fewer rings") = GreetingRings 
    newRow.Item("Greeting: Asked for your name") = GreetingAskName 
    newRow.Item("Greeting: Offered his/her name") = GreetingOfferedName 
    newRow.Item("Greeting: Mentioned TIRE PROS in the greeting") = GreetingTirePros 
    newRow.Item("Greeting: Associated acted like they are glad") = GreetingGlad 
    newRow.Item("Hold for longer than 1 minute") = holdUpdate 
    newRow.Item("Ask for the type of car AND look up the size") = LookupSize 
    newRow.Item("Ask appropriate questions about the type of driving") = DailyDriving 
    newRow.Item("1st Price Mentioned") = SingleTirePrice 
    newRow.Item("1st OTD Price Mentioned") = SingleTireOutDoorPrice 
    newRow.Item("Tire Brand") = TireBrand 
    newRow.Item("Tire Model") = TireModel 
    newRow.Item("Offered several tire choices and prices") = SeveralChoices 
    newRow.Item("Did they offer financing options") = Financing 
    newRow.Item("Mentioned benefits of the location") = Benefits 
    newRow.Item("Appointment") = Appointment 
    newRow.Item("How long does it take to put them on") = InstallTime 
    newRow.Item("Associate Score") = AssociateScore 
    newRow.Item("Time Completed") = hms 
    newRow.Item("Completed Date") = ymd 



    dt.Rows.Add(newRow) 
    Dim cb As New OleDbCommandBuilder(da) 
    cb.GetInsertCommand() 
    da.Update(dt) 
    MsgBox("Saved") 
    con.Close()

錯誤「INSERT INTO語句中的語法錯誤」可能意味着問題是，使用OLEDB命令生成器不能正確處理您使用的列名。這些行：

你有「非可變式的」列名，這基本上是任何類型的名字，你不能也作爲變量名使用的

newRow.Item("Store Number") = "1" 
    newRow.Item("Number of Rings") = Ring 
    newRow.Item("Time on Hold") = HoldTime 
    newRow.Item("Greeting: 3 or fewer rings") = GreetingRings 
    newRow.Item("Greeting: Asked for your name") = GreetingAskName 
    newRow.Item("Greeting: Offered his/her name") = GreetingOfferedName 
    newRow.Item("Greeting: Mentioned TIRE PROS in the greeting") = GreetingTirePros 
    newRow.Item("Greeting: Associated acted like they are glad") = GreetingGlad 

顯示。那只是{A-Z，0-9和「_」}。事情就像他們嚴禁可變式的名字不是無效的，但他們有專門引用，就像這樣：

newRow.Item("[Store Number]") = "1" 

不幸的是，一些連接提供商（我認爲的OleDb就是其中之一這種情況下），不能處理，並會取消引用他們，導致生成的SQL命令無效。

最簡單的解決方案是回到列號而不是名稱（可能原因是他們原來的原因）。或者，您可以重命名所有列名稱以刪除所有非變量類型的字符（空格，冒號等）。
