sql server programming : importing and maintaining identity columns

I'm would like to import records I select with a SELECT from one database to
another but maintain the identity column values. I've read where I can do
this by setting IDENTITY_INSERT ON. From the Import wizard on the
enterprise manager, I am selecting 'import using a query', then specifying:

SET IDENTITY_INSERT mytable ON; SELECT * FROM mytable WHERE fk_id = nnn; SET
IDENTITY_INSERT OFF;

This isn't working. Can someone tell me how this is done? I'm obviously
inexperienced in this area, but any help would be greatly appreciated.

Thanks,
Glenn

The error you received was probably the biggest clue.

You can only insert prior identity values into a table with an identity
column if the following conditions are met:

1.) SET IDENTITY_INSERT is ON for the table
2.) You use an explicit column list; "INSERT INTO / SELECT * FROM" will
not work, and the error surely told you so.

The "SELECT *" is alright, you just have to specify the target columns.
