更新表的存储过程

Question

我使用存储过程将记录插入到两个表中，但此刻只插入一个表中。在调试中，它不会进入try区域以便将数据存储在另一个表中。这些是两个存储过程以及用于调用存储过程的方法

存储过程：

ALTER PROCEDURE [dbo].[createRequestedItem] 
    @expense_acc varchar(50),
    @quantity_requested int,
    @inventory_acc varchar(50),
    @Req_No varchar(50),
    @Item_No varchar (50),
    @unit_of_measure varchar(15), 
    @issue_price float
AS
BEGIN
    SET NOCOUNT ON;

    INSERT INTO RequisitionItem 
    VALUES (@expense_acc, @quantity_requested, @inventory_acc, @Req_No, @Item_No,
            @unit_of_measure, @issue_price)
END

ALTER PROCEDURE [dbo].[requisition_sp_createRequisition]
    @Req_No varchar(50),    
    @Req_Date datetime,
    --@description varchar (50),
    --@quantity int,
    @employee_id nvarchar (50)
AS
BEGIN
    SET NOCOUNT ON;

    INSERT INTO Requisition 
    VALUES (@Req_No, @Req_Date, 
            --@description,
            --@quantity,
            @employee_id)
END

模特课：

  public bool createRequisition(Requisition requisition, Item requisitionitem)
  {
        int rec_upd = 0;
        bool status;

        using (SqlConnection TWCLOPConnect = new SqlConnection(connectionString.ToString()))
        {
            SqlCommand command = new SqlCommand();
            SqlCommand requestcommand = new SqlCommand();

            //Command to update the requisition table with the header information
            requestcommand.Connection = TWCLOPConnect;
            requestcommand.CommandType = CommandType.StoredProcedure;
            requestcommand.CommandText = "requisition_sp_createRequisition";

            requestcommand.Parameters.Add("@Req_No", SqlDbType.VarChar).Value = requisition.reqNumber;
            requestcommand.Parameters.Add("@Req_Date", SqlDbType.DateTime).Value = requisition.reqDate;

            requestcommand.Parameters.Add("@employee_id", SqlDbType.VarChar).Value = requisition.employeeDetails.employeeNum;

            //Command to update the issueitem table with details of the transaction
            command.Connection = TWCLOPConnect;
            command.CommandType = CommandType.StoredProcedure;
            command.CommandText = "createRequestedItem";
            command.Parameters.Add("@Req_No", SqlDbType.VarChar).Value = requisition.reqNumber;
            command.Parameters.Add("@inventory_acc", SqlDbType.Int).Value = requisition.inventory_account;
            command.Parameters.Add("@item_no", SqlDbType.VarChar);
            command.Parameters.Add("@quantity_requested", SqlDbType.Float);
            command.Parameters.Add("@issue_price", SqlDbType.Float);
            command.Parameters.Add("@expense_acc", SqlDbType.Int);
            command.Parameters.Add("@unit_of_measure", SqlDbType.VarChar);

            try
            {
                TWCLOPConnect.Open();
                requestcommand.ExecuteNonQuery();

                foreach (var item in requisition.items)
                {
                    command.Parameters["@itemnum"].Value = item.itemNumber;
                    command.Parameters["@issue_price"].Value = item.price;
                    command.Parameters["@qty"].Value = item.quantity;
                    command.Parameters["@expense_acc"].Value = item.expense_account.index;
                    command.Parameters["@unit_of_measure"].Value = item.selecteduomtext.Trim();

                    rec_upd = command.ExecuteNonQuery();
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
            finally
            {
                TWCLOPConnect.Close();
            }

            if (rec_upd > 0)
            {
                status = true;
            }
            else
            {
                status = false;
            }
        }

        return status;
}
