PostgreSQL Alter Table Drop Foreign Key

The RazorSQL alter table tool includes a Drop Foreign Key option for dropping a foreign key from a PostgreSQL database table. The drop foreign key function generates the appropriate alter table drop foreign key SQL command for dropping the key from the table.

Listed below is an example of the SQL generated by the PostgreSQL Alter Table Drop Foreign Key function:

ALTER TABLE sample.public.employee DROP CONSTRAINT employee_dno_fkey;
