Only one database can be referred to in this statement

  Explanation:  You cannot use objects from more than one database
  in a SELECT, UPDATE, DELETE or CREATE statement.  You can,
  however, refer to tables from one database in an INSERT
  statement and refer to tables in another database in the SELECT
  which provides the values for that INSERT statement if the
  insert statement is not part of a trigger definition.

  User Action:  Use separate statements for multiple database
  access.
