Oracle SQL Developer - Database Diff tables & constraints without table data
SQL Developer's Database Diff doesn't compare the data in your tables, only the table definitions.

If you check 'Tables' it by default compare ALL tables.

However, if in the proceeding wizard dialog page, you specify one or more tables, it will ONLY compare those tables.



Your output report will look like this - note there is no mention of how rows may differ between any two tables or views.
