Du måste deklarera posttypen innan du använder den i markören och sedan deklarera en variabel för posten att passera in i markören och sedan gå igenom markören.
DECLARE
TYPE dtype_amount IS RECORD (
typecode DD_DONOR.TYPECODE%TYPE,
amount DD_PLEDGE.PLEDGEAMT%TYPE
);
CURSOR donnor_pledge (p_typeamount dtype_amount ) IS
SELECT d.FIRSTNAME,
d.LASTNAME,
p.PLEDGEAMT
FROM DD_DONOR d
INNER JOIN DD_PLEDGE p
USING (IDDONOR)
WHERE d.TYPECODE = p_typeamount.typecode
AND p.PLEDGEAMT > p_typeamount.amount;
p_typeamount dtype_amount;
p_name_amount donnor_pledge%ROWTYPE;
BEGIN
p_typeamount.typecode := 'I';
p_typeamount.amount := 250;
OPEN donnor_pledge(p_typeamount);
LOOP
FETCH donnor_pledge INTO p_name_amount;
EXIT WHEN donnor_pledge%NOTFOUND;
DBMS_OUTPUT.PUT_LINE('Donor name: ' || p_name_amount.FIRSTNAME || ' ' || p_name_amount.LASTNAME);
DBMS_OUTPUT.PUT_LINE('Pledge amount: ' || p_name_amount.PLEDGEAMT);
END LOOP;
CLOSE donnor_pledge;
END;
/
eller så kan du göra det utan posten med två parametrar för markören:
DECLARE
CURSOR donnor_pledge (p_typecode CHAR, p_amount NUMBER ) IS
SELECT d.FIRSTNAME,
d.LASTNAME,
p.PLEDGEAMT
FROM DD_DONOR d
INNER JOIN DD_PLEDGE p
USING (IDDONOR)
WHERE d.TYPECODE = p_typecode
AND p.PLEDGEAMT > p_amount;
p_name_amount donnor_pledge%ROWTYPE;
BEGIN
OPEN donnor_pledge('I', 250);
LOOP
FETCH donnor_pledge INTO p_name_amount;
EXIT WHEN donnor_pledge%NOTFOUND;
DBMS_OUTPUT.PUT_LINE('Donor name: ' || p_name_amount.FIRSTNAME || ' ' || p_name_amount.LASTNAME);
DBMS_OUTPUT.PUT_LINE('Pledge amount: ' || p_name_amount.PLEDGEAMT);
END LOOP;
CLOSE donnor_pledge;
END;
