将列数据复制到Sql中的另一个表的存储过程

Question

我有两张桌子。 产品表和产品仓库。

产品表

1. 编号
2. 产品名称
3. 主仓库
4. 二级仓库
5. PrimaryWarehouseId
6. SecondaryWarehouseId

产品仓库表

• Id
• 仓库名称

是否可以将Primary Warehouse和Secondary Warehouse数据复制到Product warehouse表并使用相应的Id更新Product表？

对于每个产品，我将在Warehouse表中以2​​行结束。

感谢。

如果我理解你的问题，这是一个解决方案

declare @Product as table (
 [Id] int identity
,[Product Name] varchar(50)
,[Primary Warehouse] varchar(50)
,[Secondary Warehouse]varchar(50)
,[PrimaryWarehouseId] int 
,[SecondaryWarehouseId] int 
)


declare @ProductWarehouse as table(
 [Id] int identity
,[Warehouse Name] varchar(50)
)


insert @Product ([Product Name], [Primary Warehouse]  , [Secondary Warehouse]) Values ('P01', 'W1' , '101')
insert @Product ([Product Name], [Primary Warehouse]  , [Secondary Warehouse]) Values ('P02', 'W1' , '104')
insert @Product ([Product Name], [Primary Warehouse]  , [Secondary Warehouse]) Values ('P03', 'W2' , '102')
insert @Product ([Product Name], [Primary Warehouse]  , [Secondary Warehouse]) Values ('P04', 'W3' , '101')
insert @Product ([Product Name], [Primary Warehouse]  , [Secondary Warehouse]) Values ('P05', 'W4' , '103')
insert @Product ([Product Name], [Primary Warehouse]  , [Secondary Warehouse]) Values ('P06', '101' , 'W2')


insert @ProductWarehouse ([Warehouse Name] ) select distinct [Primary Warehouse] from @Product P  where not exists (SELECT 1  FROM @ProductWarehouse pw where p.[Primary Warehouse] = pw.[Warehouse Name]) 
insert @ProductWarehouse ([Warehouse Name] ) select distinct [Secondary Warehouse] from @Product P where not exists (SELECT 1  FROM @ProductWarehouse pw where p.[Secondary Warehouse] = pw.[Warehouse Name]) 


select * from @Product
select * from @ProductWarehouse 

update p
set [PrimaryWarehouseId] = pw.Id
from @Product p
inner join @ProductWarehouse pw 
on
p.[Primary Warehouse] = pw.[Warehouse Name] 

update p
set [SecondaryWarehouseId] = pw.Id
from @Product p
inner join @ProductWarehouse pw 
on
p.[Secondary Warehouse] = pw.[Warehouse Name]


select * from @Product

产品表

Id          Product Name  Primary Warehouse  Secondary Warehouse  PrimaryWarehouseId SecondaryWarehouseId
----------- ------------- ------------------ -------------------- ------------------ --------------------
1           P01           W1                 101                  NULL               NULL
2           P02           W1                 104                  NULL               NULL
3           P03           W2                 102                  NULL               NULL
4           P04           W3                 101                  NULL               NULL
5           P05           W4                 103                  NULL               NULL

产品仓库表

 Id          Warehouse Name

5           W4
6           102
7           103
8           104
