sql - 使用 OUTPUT 与 SELECT 一起插入

Question

我想使用 OUTPUT 将 pt_id 存储到临时表中，但我没有将 pt_id 插入 ct_tarf ，我该怎么办？

我收到以下错误:

The multi-part identifier 'pt_id' could not be bound.

查询:

DECLARE @tbl_ids_tarf TABLE (pt_id INT, pt_id_tarf INT)

INSERT INTO dbo.ct_tarf(tr_id_serv, tr_name, tr_money)
OUTPUT pt_id, inserted.tr_id INTO @tbl_ids_tarf(ptr_id, ptr_id_tarf)
   SELECT 
      pt_id_serv, pt_name, pt_money
   FROM 
      dbo.opr_prop_tar
   WHERE 
      pt_id_tarf

SQL2008+:

假设您想要将 inserted 未返回的列中的值插入到 @tbl_ids_tarf(这是 OUTPUT ... INTO 子句的目标)中 或 deleted 虚拟表，那么一种解决方案是使用 MERGE statement而不是INSERT:

DECLARE @Target TABLE (
    Col1 INT
)
INSERT  @Target VALUES (1), (2);

DECLARE @Output TABLE (Col1 INT, ColB INT);

;WITH Source
AS (
    SELECT  * 
    FROM    (VALUES (10, 100), (20, 200), (30, 300)) x(ColA, ColB)
)
MERGE INTO @Target x
USING Source y ON x.Col1 = y.ColA
WHEN NOT MATCHED BY TARGET THEN 
    INSERT (Col1) VALUES (y.ColA)
OUTPUT inserted.Col1, y.ColB INTO @Output (Col1, ColB); 
--                     ^-- y.ColB isn't returned by inserted or deleted virtual tables. 
-- inserted and deleted are based on `@Target` table [variable]

SELECT * FROM @Output;
/*
Col1        ColB
----------- -----------
10          100
20          200
30          300
