with listagg

select t.trainer_id,           t.last_name,    t.id_num,         t.language,    --t.service,    -- t.unit,    --t.rate,    tsi.info  -- join table want 1 row display in report   lms$trainers t   inner   join (select trainer_id,listagg(service || ' - ' || unit || ' - ' || rate,' - ') within group (order trainer_id) info trainer_service_info group trainer_id) tsi   on t.trainer_id = tsi.trainer_id;

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
