  You can only update one table in an UPDATE statement, but the answer to your question is yes -

  EXEC my_stored_procedure_which_updates_800_tables

  ^{“Write the query the simplest way. If through testing it becomes clear that the performance is inadequate, consider alternative query forms.” - Gail Shaw}

  There is an undocumented procedure:

  sp_MSforeachtable

  Search for it on google for more information.
