如何在SQL Server存储过程中获取刚刚插入的行(不使用触发器)？

Question

我有存储过程,在一些表中插入/更新记录.这些表的某些列具有默认值或自动递增.这就是我所拥有的:

ALTER PROCEDURE [dbo].[Usp___NewExpense]
  @iCampaignID int,
  @iCategory int,
  @iUserID int,
  @dDate Date,
  @iAmountInINR int,
  @strComments VarChar(200)
AS
BEGIN
  SET NOCOUNT ON;

  INSERT INTO dbo.Tbl_Expenses(iCampaignID, iCategory, dDate, iAmountInINR, strComments)
    VALUES (@iCampaignID, @iCategory, @dDate, @iAmountInINR, @strComments);
  -- How to get the record inserted using the above statement here without using triggers
  -- or another select statement, so that I can assign values to the following variables?

  Declare @justInsertedValue1 type1;
  Declare @justInsertedValue2 type2;
  Declare @justInsertedValue3 type3;

  INSERT INTO dbo.Tbl_SomeOtherTable(col1, col2, col3) 
  VALUES (justInsertedValue1, justInsertedValue2, justInsertedValue3);
END
GO

Tbl_Expenses有大约9列,其中两列有默认值,两列有自动增量设置.如何在我的INSERT陈述下方获得刚刚插入的记录？

我知道我可以使用SCOPE_IDENTITY()然后a SELECT,但查询可能会使它效率低下(我是对的吗？).

(通过获取刚刚插入的记录,我的意思是刚刚插入的记录的所有字段的值)

编辑:我没有为INSERT语句中的所有字段指定值.由于DEFAULT/AUTO INCREMENT约束,我希望SQL Server自动插入这些值.

您可以使用该OUTPUT子句.您甚至可以将两者inserts合并为一个复合:

create table T1 (ID int IDENTITY(1,1) not null,ColA varchar(10) not null)
create table T2 (ID int IDENTITY(1,1) not null,T1ID int not null,ColB varchar(10) not null)


--Look ma! no local variables at all
insert into T2 (T1ID,ColB)
select t1.ID,'def'
from (
    insert into T1(ColA)
    output inserted.ID
    values ('abc')
    ) t1

select * from T1
select * from T2

结果:

ID          ColA
----------- ----------
1           abc

ID          T1ID        ColB
----------- ----------- ----------
1           1           def
