OUTPUT子句中无法识别INSERT表别名

Question

Why is the INSERT table alias not recognised in the OUTPUT/INSERTED line?

EDIT: The linking table needs to be populated with new @Data_Table.Id (INSERTED.id, works), and the @NewData_Table.ObjectId (errors). SO that a 'linking table', with a foreign key relationship from @Data_Table to @Tmp_Link_Table can be created.

EDIT:

--Expected Output
--ObjectId  DataId
--11          3
--12          4
--13          5
--14          6

DECLARE @NewData_Table TABLE
(   [Data] VARCHAR(50) NOT NULL,
    ObjectId INT NOT NULL)

DECLARE @Tmp_Link_Table TABLE
(   ObjectId INT NOT NULL,
    DataId INT NOT NULL)

DECLARE @Data_Table TABLE
(   Id INT NOT NULL Identity(1,1),
    Data VARCHAR(50) NOT NULL)

-- create new objects
INSERT INTO @NewData_Table (ObjectId, Data) VALUES (11,'Data 1')
INSERT INTO @NewData_Table (ObjectId, Data) VALUES (12,'Data 2')
INSERT INTO @NewData_Table (ObjectId, Data) VALUES (13,'Data 3')
INSERT INTO @NewData_Table (ObjectId, Data) VALUES (14,'Data 4')
SELECT * FROM @NewData_Table

-- create some data
INSERT INTO @Data_Table (Data) VALUES ('Data One')
INSERT INTO @Data_Table (Data) VALUES ('Data Two')
--@Data_Table BEFORE
SELECT * FROM @Data_Table

--Q!: Why "Msg 4104, Level 16, State 1, Line 27 The multi-part identifier "d.ObjectId" could not be bound."?

INSERT INTO @Data_Table (Data)    OUTPUT d.ObjectId, INSERTED.Id INTO @Tmp_Link_Table (ObjectId, DataId)
SELECT d.Data
FROM @NewData_Table AS d 

--@Data_Table AFTER
SELECT * FROM @Data_Table

--Linked table from INSERT
SELECT * FROM @Tmp_Link_Table

Answer 1

Unfortunately, with INSERT statements, you cannot output a column that is not one of the inserted columns (though I can't seem to find a reference in the documentation that explains this).

There is a way to get around this, by using a merge statement.

For example, change this part:

INSERT INTO @Data_Table (Data)    OUTPUT d.ObjectId, INSERTED.Id INTO @Tmp_Link_Table (ObjectId, DataId)
SELECT d.Data
FROM @NewData_Table AS d 

To this:

MERGE @Data_Table AS DT
USING @NewData_Table AS NDT
ON 1 = 2 -- This never matches...
WHEN NOT MATCHED THEN -- So this is always true...
    INSERT (Data) 
    VALUES (NDT.Data) 
    OUTPUT NDT.ObjectId, INSERTED.id 
    INTO @Tmp_Link_Table (ObjectId, DataId);

You have to update your table schema and query as below to work:

DECLARE @NewData_Table TABLE
(   [Data] VARCHAR(50) NOT NULL,
    ObjectId INT NOT NULL
)

DECLARE @Tmp_Link_Table TABLE
(   ObjectId INT NOT NULL,
    DataId INT NOT NULL
)

DECLARE @Data_Table TABLE
(   Id INT NOT NULL Identity(1,1),
    Data INT
)

-- create new objects
INSERT INTO @NewData_Table (ObjectId, Data) VALUES (11,66)
INSERT INTO @NewData_Table (ObjectId, Data) VALUES (12,88)
INSERT INTO @NewData_Table (ObjectId, Data) VALUES (13,99)
INSERT INTO @NewData_Table (ObjectId, Data) VALUES (14,44)
SELECT * FROM @NewData_Table

-- create some data
INSERT INTO @Data_Table (Data) VALUES (44)
INSERT INTO @Data_Table (Data) VALUES (55)
--@Data_Table BEFORE
SELECT * FROM @Data_Table

INSERT INTO @Data_Table (Data)    OUTPUT INSERTED.Data, INSERTED.Id INTO @Tmp_Link_Table (ObjectId, DataId)
SELECT d.Data
FROM @NewData_Table AS d 

--@Data_Table AFTER
SELECT * FROM @Data_Table

--Linked table from INSERT
SELECT * FROM @Tmp_Link_Table 

Output (@Tmp_Link_Table):
