Sql 插入到具有子选择的表中？

我有这个审计表：

create table audit(
    id int IDENTITY(1, 1) NOT NULL,
    item_id int NOT NULL,
    history text NOT NULL,
)

我有一个触发器：

create trigger tr_mytable_audit ON mytable after insert, update, delete
as
select *
from inserted as i
  full join deleted as d
    on i.id = d.id
for xml path('row'), root('rows')

如何在审核表中插入记录，其中

项目id

必须是

inserted

或

deleted

中的

id

列，并且

history

列应包含该特定记录的xml

那么你是说这个

create trigger tr_mytable_audit ON mytable after insert, update, delete
as
INSERT INTO audit(item_id, history)
SELECT i1.id, (
 select *
 from inserted as i
  full join deleted as d
    on i.id = d.id
 where i.id=i1.id
 for xml path('row'), root('rows')
)
from inserted i1
UNION 
SELECT i1.id, (
 select *
 from inserted as i
  full join deleted as d
    on i.id = d.id
 where d.id=d1.id
 for xml path('row'), root('rows')
)
from deleted d1

什么是xml？mytable中有xml列吗？@TabAlleman xml字符串应该放在

历史记录

列中。
