To drop a table that is referenced by a FOREIGN KEY constraint, you must first remove the FOREIGN KEY constraint. You can do this by using the ALTER TABLE statement with the DROP CONSTRAINT clause. Here is an example:

ALTER TABLE referencing_table_name
DROP CONSTRAINT fk_constraint_name;

Make sure to replace referencing_table_name with the name of the table that has the FOREIGN KEY constraint and fk_constraint_name with the name of the FOREIGN KEY constraint.

After removing the FOREIGN KEY constraint, you can use the DROP TABLE statement to drop the table:

DROP TABLE IF EXISTS table_name;

Make sure to replace table_name with the name of the table you want to drop.
