Question

我有一个存储过程，用于将数据插入SQL Server 2008中的表。

这是我的存储过程：

ALTER PROCEDURE [dbo].[RegisterOnline_Insert]
    --@OrderType int,
    @SiteID as varchar(50),
    @CustName as varchar(100),
    @Address as varchar(255),
    @Phone as varchar(20),
    @HP as varchar(20),
    @Email as varchar(100),
    @Description as varchar(500),
    @IsValid as bit


AS

    -- interfering with SELECT statements.

    SET @InputBy = '[Website]'
    SET @addr = dbo.udf_StripHTML(@Address)

    SELECT @PostalCode = postal_code,

我的@SiteID参数值存在问题，当它处理获取某个值时，它有值并给出结果：

SELECT @PostalCode = postal_code, 
               @ftax = ftax,
               @Fibernode = fibernode,
               @Demographics2 = demographics2,
               @addrid = Address_id
        FROM dbo.TEMP_HOUSE_INFO2_SITE
        WHERE site_id = @SiteID

但是当插入到表中时，该值变为null，为什么会发生？我的插入语句有问题吗？

Answer 1

试试这个

当 SET NOCOUNT ON; 然后SP没有返回值你的 command.executenonqeury 要求结果其他方面它回滚操作所以插入语句后写选择scope_identity（）返回上次插入 PK

插入后

如果你写select scope_identity（）

select scope_identity()

现在您的处理就像这样

ALTER PROCEDURE [dbo].[RegisterOnline_Insert]
    --@OrderType int,
    @SiteID as varchar(50),
    @CustName as varchar(100),
    @Address as varchar(255),
    @Phone as varchar(20),
    @HP as varchar(20),
    @Email as varchar(100),
    @Description as varchar(500),
    @IsValid as bit


AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.

DECLARE @House as numeric(10,0)
    DECLARE @Fibernode as varchar(50)
    DECLARE @ftax as numeric(5,0)
    DECLARE @Demographics2 AS VARCHAR(50)
    DECLARE @PostalCode as varchar(10)
    DECLARE @InputBy as varchar(50)
    DECLARE @addr as varchar(max)
    DECLARE @addrid as int


    SET @InputBy = '[Website]'
    SET @addr = dbo.udf_StripHTML(@Address)

    SELECT @PostalCode = postal_code, 
           @ftax = ftax,
           @Fibernode = fibernode,
           @Demographics2 = demographics2,
           @addrid = Address_id
    FROM dbo.TEMP_HOUSE_INFO2_SITE
    WHERE site_id = @SiteID 


    SET NOCOUNT ON;
