Question

完整错误：.Net SqlClient数据提供程序INSERT语句与FOREIGN KEY约束“ FK_SalesOrder_SalesOrderHead”冲突。在数据库“ ControlSecurity”的表“ dbo.SalesOrderHead”的列“ id”中发生了冲突。

数据库表信息： FK_SalesOrder_SalesOrderHead（关系）具有来自SalesOrderHead的主键ID，并且FK = SalesOrderID。

SalesOrderInsert(Stored Procedure)

[dbo].[SalesOrderInsert] 
@SalesOrder udtSalesOrder readonly
AS
BEGIN
INSERT INTO SalesOrder
(ProductID,Quantity,UnitPrice,SalesOrderID)
SELECT ProductID,Quantity,UnitPrice,SalesOrderID
FROM @SalesOrder
END

用户定义表udtSalesOrder：

CREATE TYPE [dbo].[udtSalesOrder] AS TABLE(
[ProductID] [int] NULL,
[Quantity] [int] NULL,
[SalesOrderID] [int] NULL,
[UnitPrice] [int] NULL
)

我要向SalesOrderHead表中添加一行，然后获取作用域ID，并使用存储过程将数据表中的多行插入SalesOrder表中。所有这些都在C＃代码的一次事务中完成。但是似乎第二个ExecuteNonQuery不知道它是事务的一部分，或者我对事务范围的理解不正确。我应该在这里发布对存储过程的查询。我不确定。

using (SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["dbconn"].ToString()))
            {
                try
                {
                    con.Open();

                    using (var tran = con.BeginTransaction())
                    {
                        try
                        {

                            SqlCommand cmd = new SqlCommand("Insert into SalesOrderHead(cust_id,Description,OrderDate,DeliveryDate,Priority,CustomerRef) VALUES(@cust_id,@Description,@OrderDate,@DeliveryDate,@Priority,@CustomerRef) SELECT @id = CAST(SCOPE_IDENTITY() AS int)",con,tran);
                            cmd.Parameters.AddWithValue("@cust_id", CustomersList.EditValue);
                            cmd.Parameters.AddWithValue("@Description", Remarks.Text);
                            cmd.Parameters.AddWithValue("@OrderDate", OrderDate.DateTime);
                            cmd.Parameters.AddWithValue("@DeliveryDate", DeliveryDate.DateTime);
                            cmd.Parameters.AddWithValue("@Priority", PriorityComboBox.Text);

                            cmd.Parameters.Clear();
                            cmd.CommandText = "SalesOrderInsert";

                            //cmd = new SqlCommand("SalesOrderInsert", con, tran);
                            //cmd.Transaction = tran;
                            cmd.CommandType = CommandType.StoredProcedure;
                            //Add from SalesOrderTB to SalesOrder stored procedure
                            cmd.Parameters.AddWithValue("@SalesOrder", SalesOrderTB);
                            cmd.ExecuteNonQuery();

                            // Record inserted in both table
                            tran.Commit();

                            XtraMessageBox.Show("Added to database success");
                            con.Close();

                        {
                            tran.Rollback();
                            Console.WriteLine(ex.Source + ex.Message);
                        }
                    }

                }
                catch (Exception)
                {

                    throw;
                }
            }
