Question : Reseed All tables in db using DBCC CHECKIDENT in one command

We have a couple of databases that we are going to want to reseed the identity fields on about 100 tables to their current high record.

The reason for this is that we want to move a peer database to the "master" and the identity fields have not been incremented properly.

Is there a means of doing this for all tables in a database instead of doing each individual table one at a time?

Thanks

The code is below. Just uncomment the exec (and comment out the print, if desired).
