You can use Azure SQL Data Sync to merge those tables located on 2 different databases into a third and new database. You just need to create the table with no records, then use Azure SQL Data Sync with one-way sync from those 2 databases (member databases) to the newly created table on the new database (hub database). On the first sync data will be merged on the new table located on the hub database. Every time a record gets updated, deleted or new record arrive on the member databases then that data change is replicated to the hub database and to the merged table.
