Error While Using OUTPUT Clause - The Multi-part Identifier Could Not Be Bound

I was trying to copy child records of one parent record into another, and wanted to report back new child record id and corresponding child record id that was used to create it. I ran into run-time error with OUTPUT clause. Following is a script that will duplicate the situation I ran into:
 
CREATE TABLE Parent(
      ParentID INT NOT NULL IDENTITY(1,1) PRIMARY KEY,
      ParentName VARCHAR(50) NOT NULL)
GO
 
CREATE TABLE Child(
      ChildID INT NOT NULL IDENTITY(1,1) PRIMARY KEY,
      ParentID INT NOT NULL REFERENCES Parent(ParentID),
      ChildName VARCHAR(50) NOT NULL)
GO
 
INSERT INTO Parent(ParentName) VALUES('Parent 1')
INSERT INTO Parent(ParentName) VALUES('Parent 2')
GO
 
INSERT INTO Child(ParentID, ChildName) VALUES(1, 'Child 1')
INSERT INTO Child(ParentID, ChildName) VALUES(1, 'Child 2')
GO
 
At this stage, there Child table looks like:
 




ChildID

ParentID

ChildName


1

1

Child 1


2

1

Child 2
 
What I want to do is copy Parent 1€™s children to Parent 2, and report back which source ChildID that was used to create the new child records. So I wrote the query:
 
DECLARE @LinkTable TABLE (FromChildID INT, ToChildID INT)
 
INSERT INTO Child(ParentID, ChildName)
OUTPUT c.ChildID, inserted.ChildID INTO @LinkTable
      SELECT 2, c.ChildName
      FROM Child c
      WHERE c.ParentID = 1
 
SELECT * FROM @LinkTable
 
In the end I was expecting Child table to look like:
 




ChildID

ParentID

ChildName


1

1

Child 1


2

1

Child 2


3

2

Child 1


4

2

Child 2
 
and OUTPUT clause to return me:
 




FromChildID

ToChildID

 


1

3

Child record with ID 3 was created using ID of 1.


2

4

Child record with ID 4 was created using ID of 2.
 
 
But infact I€™m getting following error:
 
Msg 4104, Level 16, State 1, Line 9
The multi-part identifier "c.ChildID" could not be bound.
 
Any ideas on how to fix the OUTPUT clause in the query to return me the expected output?
 
Thanks
