Table Compare (found under DataSync > Tools) allows you to compare a table on your ServiceNow instance with the table in another database or another ServiceNow instance. By comparing two tables, you can see each table's record count as well as a list of record discrepancies by sys_id between the two tables that you are comparing (i.e. which records exist in one table and not in the other). 

(info) NOTETable Compare will NOT check for the most recent update of a record. It will only check for the existence of records.
