Как итерировать полученные данные из запроса select?

Question

[Black back]

Как итерировать полученный select запрос. select запрос возвращает id ники.

for cnt in select distinct his.court_case_id
....
loop

cnt не идет по итерации, походу возрвращает просто последний элемент.

CREATE OR REPLACE FUNCTION cc_case_claim_essence() 
	RETURNS TABLE(val_1 text, val_2 text, val_3 text, val_4 text, val_5 text, val_6 text, val_7 text, val_8 text, val_9 text, val_10 text, val_11 text, val_12 text) 
    LANGUAGE 'plpgsql'

    COST 100
    VOLATILE
    ROWS 1000
    
AS $BODY$
 DECLARE age_array int []:= '{1767, 842}';
 DECLARE cases int;
 DECLARE cnt int;
 DECLARE var int [];

BEGIN
	
--   DROP TABLE IF EXISTS upd;

		

  
	  for cnt in select distinct his.court_case_id

		from cc_case_claim_essence as cl
		inner join court_case_history his
		on his.court_case_id = cl.case_id
		inner join cc_penalty cp
		on his.penalty_id = cp.id
		where cl.case_id = his.court_case_id
		and cp.delivery_date is not null
		and his.case_status_id = 27
		and cp.delivery_date is not null
		and his.is_delete = false

	  loop 
	
		Update cc_case_claim_essence
		set
		result_proceeding_id = cp.result_proceeding_id,
		essence_solution_id = cp.essence_solution_id,
		delivery_time = cp.delivery_date
		from cc_case_claim_essence as cl
		inner join court_case_history his
		on his.court_case_id = cl.case_id
		inner join cc_penalty cp
		on his.penalty_id = cp.id
		where cl.case_id = cnt
		and cp.delivery_date is not null
		and his.case_status_id = 27
		and cp.delivery_date is not null
		and his.is_delete = false;
		
	end loop;

	END
	$BODY$;

ALTER FUNCTION cc_case_claim_essence()
    OWNER TO postgres;
