Question

我有一些数据，如下所示：我想将数据复制到其他用户。但是怎么做呢？数据是产品列表

select WL.Name, WL.ID,WL.UserID, WP.ID, WP.WishListID
from bdWishList WL
join
bdWishListProducts WP
on
WL.ID = WP.WishListID
where WL.UserID = '47512'

但现在我想将数据从userid = 47512复制到userid = 47509，如下所示：

但是如何复制数据？

谢谢

现在我的意思是什么呢？

两个创建表脚本是：

USE [Dynamicweb-Verploegen-Test] GO

/****** Object:  Table [dbo].[bdWishListProducts]    Script Date: 06/24/2016 09:26:32 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[bdWishListProducts](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [WishListID] [int] NULL,
    [ProductID] [nvarchar](30) NULL,
    [ProductVariantID] [nvarchar](255) NULL,
    [Quantity] [numeric](18, 0) NULL,
    [ShopID] [nvarchar](50) NULL,
 CONSTRAINT [PK_bdWishListProducts] PRIMARY KEY CLUSTERED 
(
    [ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

ALTER TABLE [dbo].[bdWishListProducts]  WITH CHECK ADD  CONSTRAINT [FK_bdWishListProducts_bdWishList] FOREIGN KEY([WishListID])
REFERENCES [dbo].[bdWishList] ([ID])
GO

ALTER TABLE [dbo].[bdWishListProducts] CHECK CONSTRAINT [FK_bdWishListProducts_bdWishList]
GO

和

USE [Dynamicweb-Verploegen-Test]
GO

/****** Object:  Table [dbo].[bdWishList]    Script Date: 06/24/2016 09:28:38 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

SET ANSI_PADDING ON
GO

CREATE TABLE [dbo].[bdWishList](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [UserID] [int] NULL,
    [Name] [varchar](255) NULL,
    [DateCreated] [datetime] NULL,
    [DateModified] [datetime] NULL,
    [Active] [bit] NULL,
 CONSTRAINT [PK_bdOrderTemplate] PRIMARY KEY CLUSTERED 
(
    [ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

SET ANSI_PADDING OFF
GO

ALTER TABLE [dbo].[bdWishList] ADD  CONSTRAINT [DF_bdWishList_DateCreated]  DEFAULT (getdate()) FOR [DateCreated]
GO

ALTER TABLE [dbo].[bdWishList] ADD  CONSTRAINT [DF_bdWishList_DateModified]  DEFAULT (getdate()) FOR [DateModified]
GO

ALTER TABLE [dbo].[bdWishList] ADD  CONSTRAINT [DF_bdWishList_default]  DEFAULT ((1)) FOR [Active]
GO

@ gofr1 问题是：

 user1: 
    userlist1: products: user1List1product1, user1List1product2
    userlist2, products: user1List2Product3, user1List2Product4

    User2:
    Userlist3, products: user2List3Prodcuts5
    Userlist4, products User2Lis4tProduct6

    Then I copy the lists from User1 to User2:

    lists user2:
    userlist1: products: user1List1product1, user1List1product2
    userlist2, products: user1List2Product3, user1List2Product4

    Userlist3, products: user2List3Prodcuts5, User2Lis4tProduct6
    Userlist4, products : empty and it has to be:
 Userlist4, products User2Lis4tProduct6

因此复制了所有列表，但不复制产品。

Answer 1

根据您桌子的创建脚本，我建议您先插入bdWishList：

DECLARE @wlid int = <>

INSERT INTO bdWishList ([UserID],[Name]) --[DateCreated],[DateModified],[Active] will get default values
SELECT  47509,
        WL.Name  --Maybe you should use another name
FROM bdWishList WL
WHERE WL.UserID = 47512 and WL.ID = @wlid

然后获取插入行的ID：

DECLARE @id int
SELECT @id = IDENT_CURRENT('bdWishList')

然后在bdWishListProducts中插入数据：

INSERT INTO bdWishListProducts ([WishListID], [ProductID], [ProductVariantID], [Quantity], [ShopID])
SELECT  @id, 
        WP.ProductID,
        WP.ProductVariantID,
        WP.Quantity,
        WP.ShopId
FROM bdWishList WL
INNER JOIN bdWishListProducts WP
    ON WL.ID = WP.WishListID
where WL.UserID = 47512 and WL.ID = @wlid

如果您想一次复制许多愿望清单：

DECLARE @temp TABLE (  
    [NewId] int,  
    [OldId] int
)

MERGE INTO ##bdWishList as target
USING (
    SELECT  ID,
            47509 as UserID, 
            WL.Name  --Maybe you should use another name
    FROM ##bdWishList WL
    WHERE WL.UserID = 47512
    ) AS source 
ON 1 = 0
WHEN NOT MATCHED THEN
    INSERT ([UserID],[Name])
    VALUES (source.[UserID],source.[Name])
    OUTPUT inserted.ID, source.ID 
    INTO @temp;


INSERT INTO bdWishListProducts ([WishListID], [ProductID], [ProductVariantID], [Quantity], [ShopID])
SELECT  t.[NewId], 
        WP.ProductID,
        WP.ProductVariantID,
        WP.Quantity,
        WP.ShopId
FROM bdWishList WL
INNER JOIN bdWishListProducts WP
    ON WL.ID = WP.WishListID
INNER JOIN (SELECT DISTINCT [NewId],[OldId] FROM @temp) t
    ON t.[OldId] = WL.ID
where WL.UserID = 47512

Answer 2

最简单的方法是插入声明ala：

Insert into bdWishListProducts (
select  @NewID, WP.ID, WP.WishListID
from bdWishList WL
join
bdWishListProducts WP
on
WL.ID = WP.WishListID
where WL.UserID = '47512'

（假设您不想要单独的心愿单ID

更明智的做法是

Insert into bdWishList (name, id, userid) Values ('NEWNAME', 'NewID', 'USERID') 

Insert into bdWishListProducts (
select   WP.ID, NEWID 
from bdWishList WL
join
bdWishListProducts WP
on
WL.ID = WP.WishListID
where WL.UserID = '47512'
)

显然 - 您需要确保提供所有必填字段 - 我只是尽快输入

将日期复制给其他用户
