Thus spake Ilan Fait > 1) I need to build a trigger that every time I insert into the table > one of the columns will get +1 number. The easiest way in PostgreSQL is to simply make the field a serial type. CREATE TABLE mytable ( id SERIAL PRIMARY KEY, myname TEXT); > 2) what is equal to 'sysdate' (to get/put the system date in a > table) in PostGerSQL. Again, the table definition can handle this. CREATE TABLE mytable ( id SERIAL PRIMARY KEY, mydate DATE DEFAULT CURRENT_DATE, myname TEXT); You should check out the docs on the web site. They are quite comprehensive. -- D'Arcy J.M.
