您可以使用 Insert 语句的输出子句批量捕获生成的 Id。
例如:
Create Table dbo.Source (
FirstName nvarchar(100),
LastName nvarchar(100)
);
Create Table dbo.Attrs (
Id int Identity Not Null Primary Key,
Name nvarchar(100) Not Null,
DefaultVal nvarchar(100)
);
Create Table dbo.Table1 (
Id Int Identity Not Null Primary Key,
FirstName nvarchar(100),
LastName nvarchar(100)
);
Create Table dbo.Table2 (
Id int Identity Not Null Primary Key,
Table1ID int Not Null Foreign Key References dbo.Table1 (Id),
AttrId int Not Null Foreign Key References dbo.Attrs (Id)
);
Insert Into dbo.Source Values
(N'Mickey', N'Mouse'),
(N'Donald', N'Duck'),
(N'Goofy', Null);
Insert Into dbo.Attrs Values
('Size', 'Small'),
('Wings', 'No');
Declare @Temp1 Table (Id Int, FirstName nvarchar(100), LastName nvarchar(100))
Declare @Temp2 Table (Id int, Table1ID int, AttrId int)
Insert Into dbo.Table1
(FirstName, LastName)
Output
inserted.Id, inserted.FirstName, inserted.LastName
Into
@Temp1
Select
FirstName, LastName
From
dbo.Source
Insert Into dbo.Table2
(Table1ID, AttrId)
Output
inserted.Id, Inserted.Table1ID, Inserted.AttrID
Into
@Temp2
Select
t.Id,
a.Id
From
@Temp1 t
Cross Join
dbo.Attrs a
Select * From @Temp2
