Обсуждение: select result into string's array
Hi, I need to store the result of select into an array of string: /create or replace function search_engine.test/ /(/ /)/ / returns integer as $$/ /declare/ / m_array text[];/ /begin/ / for m_array in select * from my_table loop/ / raise notice 'valor 1: %',m_array;/ / end loop;/ / return 1;/ /end; $$ LANGUAGE plpgsql;/ This launch this errors: /ERROR: array value must start with "{" or dimension information SQL state: 22P02 Context: PL/pgSQL function "test"line 4 at FOR over SELECT rows/ Is it possible do this?? May I choose another way? Thanks in advance Alberto,
