在asp.net中将表单值插入数据库

Question

我正在尝试将表单字段valus插入到oracle数据库表中。我已经尝试了以下代码。但我得到的错误像“缺少表达”。请帮帮我。

Default.aspx代码：

对于Oracle，绑定变量将以查询中的colon (:)开头，并且在设置时，您只需提及不带冒号的绑定变量名称。

            cmd.CommandText = "Insert into Activity_Main_372640(ACTIVITY_ID,ACTIVITY_TYPE,TICKET_ID,TICKET_CATEGORY,TICKET_DESCRIPTION,ACTIVITY_DESCRIPTION,MODULE,PRIORITY,RESOURCE_NAME,CREATION_DATE,ASSIGNMENT_DATE,COMPLITION_DATE,STATUS,REMARKS,EFFORTS) VALUES(:Parameter1,:Parameter2,:Parameter3,:Parameter4,:Parameter5,:Parameter6,:Parameter7,:Parameter8,:Parameter9,:Parameter10,:Parameter11,:Parameter12,:Parameter13,:Parameter14,:Parameter15)";
            cmd.Parameters.Add(new OracleParameter("Parameter1",id));
            cmd.Parameters.Add(new OracleParameter("Parameter2", Activity_type));
            cmd.Parameters.Add(new OracleParameter("Parameter3", Ticket_no));
            cmd.Parameters.Add(new OracleParameter("Parameter4", tkt_category));
            cmd.Parameters.Add(new OracleParameter("Parameter5", tkt_desc));
            cmd.Parameters.Add(new OracleParameter("Parameter6", Act_desc));
            cmd.Parameters.Add(new OracleParameter("Parameter7", module));
            cmd.Parameters.Add(new OracleParameter("Parameter8", priority));
            cmd.Parameters.Add(new OracleParameter("Parameter9", resource));
            cmd.Parameters.Add(new OracleParameter("Parameter10", creation_date));
            cmd.Parameters.Add(new OracleParameter("Parameter11", Assigned_date));
            cmd.Parameters.Add(new OracleParameter("Parameter12", completed_date));
            cmd.Parameters.Add(new OracleParameter("Parameter13", status));
            cmd.Parameters.Add(new OracleParameter("Parameter14", remarks));
            cmd.Parameters.Add(new OracleParameter("Parameter15", Efforts));
            var rowsUpdated = cmd.ExecuteNonQuery();
