如何从PostgreSQL数据库中删除表*或*视图？

DROP TABLE user_statistics;

DROP VIEW user_statistics;

完整语法：

DROP TABLE

DROP VIEW

如果你想要一个完整的功能,我尝试过这样的事情：

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;
