[.NET] 透過 window form 存圖檔至 Oracle DB
請輸入專案類型(網站專案或者應用程式專案)：應用程式專案
我寫了一個 window form,
有一個 textBox 可以輸入來源檔路徑,
在遠端的 Oracle DB (8i) 建了一個 table,
欄位與格式如下,
欄位 格式
PIC_ID --> Number
PIC --> BLOB
想要把來源檔路徑的圖片傳到 DB server,
存在 DB 中,
(這是初步, 之後希望透過讀DB然後秀出圖檔在 window form 畫面上)
不過遇到一個問題...(底下的 code 是 google 上找到拿來修改的)
在執行到 cmd.ExecuteNonQuery() 這一行的時候,
會出現 ORA 錯誤....
ORA-01036: illegal variable name/number
請教一下到底是哪裡有問題....>"<
謝謝...
