There are two general types of constraints:

  • Geometric constraints control the relationships of objects with respect to each other.

  3. Example. If you had created a foreign key as follows:

Where are constraints stored in Oracle?

Other Queries for Constraints

select table_name from user_constraints where (r_constraint_name) in ( select constraint_name from user_constraints where table_name = ‘T’ and constraint_type in ( ‘P’, ‘U’ ) ); So, we can easily find all the constraints on the table in oracle using data dictionary views.
