您需要记录/跟踪在第一次插入时创建的 IDENTITY ID。
但是您需要以基于 SET 的方式进行跟踪。 （我认为您只使用“OUTPUT Inserted.MemberId”跟踪单个项目）
来吧：
DECLARE @tmpTable TABLE (UserId INT, Name nvarchar(50), Department nvarchar(50))
DECLARE @xml XML=
N'<user><userId>1</userId><name>John</name><department>A</department></user>
<user><userId>2</userId><name>Jane</name><department>B</department></user>';
insert into @tmpTable
SELECT
a.b.value('(./userId)[1]', 'int') AS UserId,
a.b.value('(./name)[1]', 'nvarchar(50)') AS Name,
a.b.value('(./department)[1]', 'nvarchar(50)') AS Department
FROM @xml.nodes('/user') a(b)
create table #AUDIT ( EntityKey int not null default -1 , OldMyName varchar(128) null, NewMyName varchar(128) null , Tag varchar(64) );
CREATE TABLE #MEMBERSREALTABLEMIMIC (MyIdentity INT IDENTITY (3001, 3) , MyName varchar(128) )
/* replace my #MEMBERSREALTABLEMIMIC with your real dbo.Member table here..i had to fake it since I don't have the DDL to dbo.Member */
INSERT INTO #MEMBERSREALTABLEMIMIC (MyName)
output inserted.MyIdentity , null , inserted.MyName , 'Employee Inserted' into #AUDIT ( EntityKey , OldMyName , NewMyName , Tag)
SELECT Name FROM @tmpTable
Select * from #MEMBERSREALTABLEMIMIC
Select * from #AUDIT
DROP table #MEMBERSREALTABLEMIMIC
DROP table #AUDIT
您可以使用#AUDIT 表插入到其他表中。因为您现在有IDENTITY 的记录。 （带有相应的名称）。
注意，如果“MyName”没有唯一约束，这可能会失败。
您“审核” INSERT 的原因是为了避免针对新 IDENTITY 访问 dbo.Member 表......（假设您在 dbo.Member 表中已经有 1,000,000 行......审核将阻止重新查看那张桌子）

这是一个例子：
create table PrimaryHolderTable ( i int identity (1001,2) not null primary key, j int not null unique )
create table #OutputResultsHolder ( i int not null, j int not null)
insert into PrimaryHolderTable (j)
output inserted.i, inserted.j into #OutputResultsHolder
select top 10 o.object_id from sys.objects as o order by o.object_id desc --<< from sys.objects is there just to provide some rows
select * from #OutputResultsHolder
drop table #OutputResultsHolder, PrimaryHolderTable;
go
create table dbo.EmployeeTable ( EmpKey int identity(1001,2) , EmpAge int not null );
create table dbo.AuditTable ( EntityKey int not null default -1 , OldValue int null, NewValue int null , Tag varchar(64) );
insert into dbo.EmployeeTable (EmpAge)
output inserted.EmpKey , null , inserted.EmpAge , 'Employee Inserted' into dbo.AuditTable ( EntityKey , OldValue , NewValue , Tag)
values( 18 );
insert into dbo.EmployeeTable (EmpAge)
output inserted.EmpKey , null , inserted.EmpAge , 'Employee Inserted' into dbo.AuditTable ( EntityKey , OldValue , NewValue , Tag)
values( 20 );
insert into dbo.EmployeeTable (EmpAge)
output inserted.EmpKey , null , inserted.EmpAge , 'Employee Inserted' into dbo.AuditTable ( EntityKey , OldValue , NewValue , Tag)
values( 22 );
update dbo.EmployeeTable
set EmpAge = EmpAge + 1
output inserted.EmpKey , deleted.EmpAge, inserted.EmpAge , 'Employee Updated' into dbo.AuditTable ( EntityKey , OldValue , NewValue , Tag)
where EmpAge <=20;
delete from dbo.EmployeeTable
output deleted.EmpKey , deleted.EmpAge, NULL , 'Employee Deleted' into dbo.AuditTable (EntityKey , OldValue , NewValue , Tag)
where EmpAge > 0; --Test multi rows
select * from dbo.EmployeeTable; --<<will be empty at this point
select * from dbo.AuditTable;
drop table dbo.EmployeeTable, dbo.AuditTable;
go
追加
注意，您不能“跳过”#AUDIT 表。 #AUDIT 表只能包含来自您的 PARENT INSERT 的信息（您拥有的任何属性，当然还有新的 IDENTITY，这就是您所追求的）
这就是我认为你所追求的。 （使用小提琴）
