How Can I Find Tables Referencing a Given Table in Oracle SQL Developer?

Finding Tables Referencing a Given Table in Oracle SQL Developer

In Oracle SQL Developer, finding tables that reference a given table can be challenging. While the program provides options to view constraints (foreign keys) and dependencies (indicating which packages and objects refer to a table), there is currently no direct UI element for identifying references made from other tables.

To overcome this limitation, you can execute a manual SQL query or use an external tool that offers such functionality. One such tool is PLSQL Developer, which employs the following SQL:

select table_name, constraint_name, status, owner
from all_constraints
where r_owner = :r_owner
and constraint_type = 'R'
and r_constraint_name in
 (
   select constraint_name from all_constraints
   where constraint_type in ('P', 'U')
   and table_name = :r_table_name
   and owner = :r_owner
 )
order by table_name, constraint_name

In this query, replace :r_owner with the schema and :r_table_name with the table you are checking. Remember that names are case-sensitive.

Note: Oracle SQL Developer's report tab has an option called "All Tables / Dependencies," but this refers to dependencies between objects accessible to the current user, not references from other tables.
