Alter table error adding 2 columns

Question

Database:POSTGRESQL

I have a table location_type with 2 columns id,name. I want to delete column name and add 2 other columns:county,city. However I get error and I can't figure out why. This is what I tried:

ALTER TABLE location_type
DROP COLUMN name;

ALTER TABLE location_type
ADD (county character varying(255) NOT NULL,
     city character varying(255) NOT NULL);

Maybe someone can see what I am doing wrong. Any suggestions are appreciated. Thanks.

Your syntax is wrong. Try this [Doc]:

ALTER TABLE location_type
    ADD county character varying(255) NOT NULL,
    ADD city character varying(255) NOT NULL;
