Bagaimana cara menghapus tampilan tabel * atau * dari database PostgreSQL?

DROP TABLE user_statistics;

DROP VIEW user_statistics;

sintaks lengkap:

DROP TABLE

DROP VIEW

Dan jika Anda ingin fungsi yang lengkap, saya mencoba sesuatu seperti ini:

CREATE OR REPLACE FUNCTION delete_table_or_view(objectName varchar) RETURNS integer AS $$
DECLARE
    isTable integer;
    isView integer;
BEGIN
    SELECT INTO isTable count(*) FROM pg_tables where tablename=objectName;
    SELECT INTO isView count(*) FROM pg_views where viewname=objectName;

    IF isTable = 1 THEN
        execute 'DROP TABLE ' || objectName;
        RETURN 1;
    END IF;

    IF isView = 1 THEN
        execute 'DROP VIEW ' || objectName;
        RETURN 2;
    END IF;

    RETURN 0;

END;
$$ LANGUAGE plpgsql;
