INSERT table alias not recognised in the OUTPUT clause - sql

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):
