使用输出语句插入已删除的数据以及一些硬编码值

Question

我想将行从一个表移动到另一个表,delete from [foo] output deleted.[col] into [bar] (col)看起来是一个不错的选择.

但是列不完全相同.所以我想在目标表中插入一些硬编码值(理想情况下是编程确定的值).

我设置了几张表来演示.

create table delete_output_test (
    thing1 int not null,
    thing2 varchar(50),
    thing3 varchar(50)
)

create table delete_output_test2 (
    thing1 int not null,
    thing2 varchar(50),
    thing3 varchar(50),
    thing4 int
)

insert into delete_output_test values (0, 'hello', 'world'),
                                      (1, 'it''s', 'me'),
                                      (2, 'i', 'was'),
                                      (3, 'wondering', 'if')

如果我不太需要,现在从一张桌子移动到另一张桌子工作正常......

delete from delete_output_test2
output deleted.thing1,
       deleted.thing2,
       deleted.thing3
into delete_output_test
       (thing1,
        thing2,
        thing3)

但是,如果我想填充最后一列怎么办？

delete from delete_output_test2
output deleted.thing1,
       deleted.thing2,
       deleted.thing3
into delete_output_test
       (thing1,
        thing2,
        thing3,
        4)

'4'附近的语法不正确.期待'.',ID,PSEUDOCOL或QUOTED_ID.

我对SQL很新,所以我甚至不确定那些东西是什么.

那么为什么我不能对要插入的值进行硬编码？如果我想变得聪明,甚至可以4用一些select陈述代替？

好了,delete_output_test没有一列命名4或thing4但是delete_output_test2确实.所以你可以这样做:

delete from delete_output_test
output deleted.thing1,
       deleted.thing2,
       deleted.thing3,
       4
into delete_output_test2
       (thing1,
        thing2,
        thing3,
        thing4);
select * from delete_output_test2;
