插入刪除的數據，加上一些硬編碼的值，輸出語句

Question

我想將行從一個表移動到另一個表，delete from [foo] output deleted.[col] into [bar] (col)看起來是一個不錯的選擇。

但列不相同。所以我想插入一些硬編碼的值（理想的編程決定的值）到目標表中。

我設置了幾張表來演示。

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') 

現在從一個表移動到罰款，如果我不是太貧窮的另一個作品...

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

但如果我要來填充最後一列是什麼？

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

附近有語法錯誤 '4'。期待'。'，ID，PSEUDOCOL或QUOTED_ID。

我對SQL相當陌生，所以我甚至不確定這些東西是什麼。

那麼，爲什麼我不能硬編碼插入的值？或者，如果我想變得聰明，甚至用4替換一些select聲明？

Answer 1

那麼，delete_output_test沒有列名爲4或thing4但delete_output_test2呢。所以，你可以這樣做：

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;

回報：

+--------+-----------+--------+--------+ 
| thing1 | thing2 | thing3 | thing4 | 
+--------+-----------+--------+--------+ 
|  0 | hello  | world |  4 | 
|  1 | it's  | me  |  4 | 
|  2 | i   | was |  4 | 
|  3 | wondering | if  |  4 | 
+--------+-----------+--------+--------+ 

Answer 2

的要求是有點好奇，但我認爲你可以使用CTE或子查詢做到這一點：

with todelete as (
     select dot.*, 4 as col4 
     from delete_output_test 
    ) 
delete from todelete 
    output deleted.thing1, deleted.thing2, deleted.thing3, deleted.col4 
    into delete_output_test2(thing1, thing2, thing3, col4); 

你需要確保delete_output_test有其他列的空間。
