光标 <cursor name> 不存在，34000 | Postgres

Question

我正在尝试执行以下代码，但我遇到了错误，因为 光标 v1_cur 不存在，34000。谁能告诉我错误在哪里？

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 后必须跟游标名称 (c1_cur)，而不是记录。

光标 <cursor name> 不存在，34000 | Postgres

cursor <cursor name> does not exist, 34000 | Postgres

postgresql

cursor
