sql - How to update data for each row using function and data from another table? -

-

i've got problem updating data each row in acrticles_pl_vector table using function in set clause , data take table.

for example have pseudocode:

create or replace function updatetsvector ()  returns status $$ begin     each row othertable      update acrticles_pl_vector      set vector = to_tsvector('polish', othertable.title || othertable.content);      id = othertable.id  end; $$ language plpgsql

thanks in advance!

create or replace function updatetsvector () returns void $$   update acrticles_pl_vector     set locale = 'pl', vector = to_tsvector('polish', ot.title || ot.content     othertable ot     id = ot.id; $$ language sql;
