Possible to get PrimaryKey IDs back after a SQL BulkCopy?

In that scenario, I would use SqlBulkCopy to insert into a staging table (i.e. one that looks like the data I want to import, but isn't part of the main transactional tables), and then at the DB to a INSERT/SELECT to move the data into the first real table.

Now I have two choices depending on the server version; I could do a second INSERT/SELECT to the second real table, or I could use the INSERT/OUTPUT clause to do the second insert , using the identity rows from the table.

For example:

     -- dummy schema
     CREATE TABLE TMP (data varchar(max))
     CREATE TABLE [Table1] (id int not null identity(1,1), data varchar(max))
     CREATE TABLE [Table2] (id int not null identity(1,1), id1 int not null, data varchar(max))

     -- imagine this is the SqlBulkCopy
     INSERT TMP VALUES('abc')
     INSERT TMP VALUES('def')
     INSERT TMP VALUES('ghi')

     -- now push into the real tables
     INSERT [Table1]
     OUTPUT INSERTED.id, INSERTED.data INTO [Table2](id1,data)
     SELECT data FROM TMP

If your app allows it, you could add another column in which you store an identifier of the bulk insert (a guid for example). You would set this id explicitly.

Then after the bulk insert, you just select the rows that have that identifier.
