Question

我有一个更新表格的方法如下：

  public static Boolean updateRequest(String _VUserName, DateTime newToDate)
{
    SqlConnection conn = getConnection();
    SqlCommand command = new SqlCommand();
    command.CommandText = "UPDATE Requests SET [To] = @ToDate FROM Requests INNER JOIN "+
                  "VUsers ON Requests.UserRef = VUsers.VUserID WHERE (VUsers.VUserName = @VUserName)";

    command.Parameters.AddWithValue("@ToDate", newToDate);
    command.Parameters.AddWithValue("@VUserName", _VUserName);

    conn.Open();
    try
    {
        command.ExecuteNonQuery();
        return true;

    }
    catch (Exception)
    {
        return false;

    }
    conn.Close();
}

但是_COMPlusExceptionCode = -532459699异常

失败了

任何帮助？

请检查以下link“SQL Server拒绝添加记录，因为它不符合表列规范”

它看起来与您的更新语句有关。而是像这样重写它。

"UPDATE Requests SET [To] = @ToDate WHERE ...

C＃更新语句失败错误：_COMPlusExceptionCode = -532459699
