Question

我正在尝试执行以下代码，但是由于 cursor v1_cur不存在，34000 ，我遇到了错误。有人可以让我知道错误在哪里吗？

CREATE OR REPLACE FUNCTION data_del(
   OUT p_message_out CHARACTER VARYING,
   OUT p_sqlstate_out CHARACTER VARYING
   )
   RETURNS RECORD AS
$BODY$

DECLARE 
v_msg CHARACTER VARYING(160);
v_sqlstate CHARACTER VARYING(6);
v1_cur RECORD;
c1_cur CURSOR FOR SELECT * FROM mydata WHERE event_timestamp<=CURRENT_TIMESTAMP - INTERVAL '15 Days';

BEGIN
OPEN c1_cur;
LOOP
FETCH c1_cur INTO v1_cur;
EXIT WHEN NOT FOUND;
DELETE FROM mydata WHERE CURRENT OF v1_cur;
END LOOP;
CLOSE c1_cur;

v_msg = 'Data deleted successfully.';
v_sqlstate = 1; 

p_message_out = v_msg;
p_sqlstate_out = v_sqlstate;


EXCEPTION WHEN OTHERS THEN
p_message_out=SQLERRM;
p_sqlstate_out=SQLSTATE;

END;
$BODY$
  LANGUAGE plpgsql VOLATILE SECURITY DEFINER

Answer 1

CURRENT OF后面必须是游标名称（c1_cur），而不是记录。

光标<cursor name =“”>不存在，34000 | Postgres
