INSERT-OUTPUT including column from other table

Question

I have a stored procedure that needs to insert into three different tables, but I need to get the ID generated from the one input and use that to insert into the next table. I'm familiar with the INSERT-OUTPUT construct, but I'm not sure how to go about using it in this particular case.

DECLARE @guids TABLE ( [GUID] UNIQUEIDENTIFIER ); DECLARE @contacts TABLE ( [ContactID] INT, [GUID] UNIQUEIDENTIFIER ); DECLARE @mappings TABLE ( [TargetID] INT, [GUID] UNIQUEIDENTIFIER );  INSERT @guids ( [GUID] ) ...  INSERT [Contacts] ( [FirstName], [LastName], [ModifiedDate] ) OUTPUT [inserted].[ContactID], g.[GUID] INTO @contacts SELECT [First_Name], [Last_Name], GETDATE() FROM [SourceTable] s JOIN @guids g ON s.[GUID] = g.[GUID]  INSERT [TargetTable] ( [ContactID], [License], [CreatedDate], [ModifiedDate] ) OUTPUT [inserted].[TargetID], c.[GUID] INTO @mappings SELECT c.[ContactID], [License], [CreatedDate], [CreatedDate] FROM [SourceTable] s JOIN @contacts c ON s.[GUID] = c.[GUID]   INSERT [Mappings] ( [TargetID], [SourceGUID] ) SELECT [TargetID], [GUID] FROM @mappings 

But I get the following errors:

The multi-part identifier "g.GUID" could not be bound.

The multi-part identifier "c.GUID" could not be bound.

I'll get similar errors if I use s.GUID instead. Is it possible to do a kind of join in the OUTPUT clause?

I'm not sure if that is the best option, but it seems you can do the trick using MERGE :

MERGE [Contacts]  trgt USING  (     SELECT [First_Name], [Last_Name], g.[GUID] as [GUID]   FROM [SourceTable] s   JOIN @guids g ON s.[GUID] = g.[GUID] )src ON (1=0) WHEN NOT MATCHED THEN INSERT ( [FirstName], [LastName], [ModifiedDate] )  VALUES (src.[First_Name],src.[Last_Name], GETDATE()) OUTPUT [inserted].[ContactID], src.[GUID] INTO @contacts
