Hi everybody, thanks for your answers about hardware requirements. DB design
was succesful and now we are migrating stored procedures from oracle to
PostgreSQL.
I can't handle cursors very well in PostgreSQL, for example, i need to
migrate this stored procedure:
CREATE OR REPLACE PROCEDURE LOAD_EXP AS
cursor c_exp IS
select C_COD_PRE from temp_codpre;
BEGIN
for cur1 in c_exp loop
update lcmap_ctrcre
set v_cod_pcar = '07'
where c_num_exp = cur1.C_COD_PRE;
commit;
end loop;
end LOAD_EXP;
/
and what i did in PostgreSQL was:
CREATE OR REPLACE FUNCTION LOAD_EXP() RETURNS VOID AS $$
DECLARE
c_exp refcursor;
BEGIN
open c_exp for select C_COD_PRE from temp_codpre;
loop
FETCH c_exp INTO VARIABLE
IF NOT FOUND THEN
EXIT;
END IF;
update lcmap_ctrcre
set v_cod_pcar = '07'
where c_num_exp = cur1.C_COD_PRE;
end loop;
close c_exp;
END;
$$ LANGUAGE plpgsql;
select LOAD_EXP()
My really big doubt is about what VARIABLE must be and if this function is
efficient how is it written.
I'll appreciate any advice.
Rafael
