SqlException：數據類型tinyint，值= -1的算術溢出錯誤

我一直試圖傳遞一個int值爲1到我的存儲過程，但我總是得到一個異常「數據類型tinyint的算術溢出錯誤，值= -1。「 int的值是1，但例外說明它的-1，我不明白爲什麼。無論如何，我已經發布了下面的代碼。我可能錯過了一些明顯的東西。SqlException：數據類型tinyint，值= -1的算術溢出錯誤

.NET代碼

protected void btnUpdate_Click(object sender, EventArgs e) 
    { 
     string result = ""; 
     string currentFileName = (string)(Session["FileName"]); 
     string FileName = txtUploadStatus.Text; 
     string sSQL = "usp_imageloader_update"; 
     int ImgID = (int)(Session["ImgID"]); 

     using (SqlConnection dbConnection = new SqlConnection(CKS_app_settings.sql_conn_string_db)) 
     { 
      // SqlTransaction tn=null; 
      try 
      { 
       dbConnection.Open(); 
       //start Transaction 
       // tn = dbConnection.BeginTransaction(); 
       SqlCommand command = new SqlCommand(sSQL, dbConnection); 
       //command.Transaction = tn; 
       command.CommandText = sSQL; 
       command.CommandType = CommandType.StoredProcedure; 
       command.CommandTimeout = 1024; 
int Active = 0; 

       if (chkActive.Checked == true) 
       { 
        Active = 1; 
       } 
       else 
       { 

       } 

       if (currentFileName != FileName) 
       { 
        // Split entire file path to grab filename 
        string[] split = txtUploadStatus.Text.Split(new char[] { '\\' }); 
        FileName = split[06]; 
       } 
       else 
       { 
        FileName = txtUploadStatus.Text; 
       } 

       command.Parameters.AddWithValue("@p_image_id", ImgID); 
       command.Parameters.AddWithValue("@p_filename", FileName); 
       command.Parameters.AddWithValue("@p_Active", Active); 
       command.Parameters.AddWithValue("@p_url", txtUrl.Text); 
       command.Parameters.AddWithValue("@p_Title", txtImgTitle.Text); 
       command.Parameters.AddWithValue("@p_alt_text", txtAlt.Text); 
       int rowsAffected = command.ExecuteNonQuery(); 
      } 
      catch (SqlException ex) 
      { 
       // throw ex; 

       //If it failed for whatever reason, rollback the //transaction 
       //tn.Rollback();       
       //No need to throw because we are at a top level call and //nothing is handling exceptions 
       result = ex.InnerException.Message; 
      }

你有一個減號只是呼叫之前，在update語句@p_active：

活動= - @ p_Active

可能是你的問題！

哇，我覺得有點傻，即固定它。謝謝！ – 2012-01-09 12:35:37

不用擔心，輕鬆完成:) – Timbo 2012-01-09 12:48:28

在您的存儲過程中，在將值分配給活動時，@p_Active之前有一個負號。
