我試圖創建一個用戶提交個人信息並將數據保存在Access數據庫中的小應用程序。連接到ASP.Net中的自定義數據庫
返回的錯誤沒有任何意義,因爲我試圖將正確數量的值插入表中。
這些值是第一個,最後一個,年齡和性別。
這是我的代碼,然後按我提交按鈕時得到的錯誤。
感謝您的幫助。

謝謝,但這不起作用 – Geo 2012-03-03 06:28:22
您的訪問表中可能有一些需要插入值的列。他們中的任何一個是否設置爲非空?還是有一個主鍵需要一個值?您在上面提到了「ID」字段,但主鍵不會插入默認值,除非您已將其設置爲「自動編號」列。 – Bauhaus 2012-03-03 06:37:40
ID正在搞亂我的INSERT。感謝您的幫助 – Geo 2012-03-05 00:51:32
