存儲過程未更新數據庫

Question

問題：

數據庫未更新，但我不確定它丟棄的位置。

我在過去使用過很多，但我看不出爲什麼這不起作用。如果我能看到如何運行存儲過程的錯誤測試，我懷疑這會有所幫助。

測試：

我通過變量的標籤，在.aspx代碼存儲過程請求查詢的值是否存在（左代碼）

變化INT爲varchar在存儲過程之後

查詢：

我該如何解決這個問題，然後我怎麼能運行測試，以找到在未來的問題

UPDATE Stored Procedure not Updating

Answer 1

而不是

.Parameters.AddWithValue("@ActionID", Session("ActionID").ToString) 

嘗試

.Parameters.Add("@ActionId",SqlDbType.Int) 
.Parameters("@ActionId").Value = CInt(Session("ActionId")) 

我假設它是你逝去的

int值

.Parameters.AddWithValue做一個隱式類型轉換，也許這是什麼原因造成您的問題
