kembalikan satu baris dalam prosedur tersimpan di Oracle

Anda perlu memilih bidang tertentu untuk dimasukkan ke dalam hasil jika Anda akan menggunakannya seperti itu.

declare or replace procedure select_row 
(
    bookingid in integer,
    result out varchar2
) as 
begin
    select booking_name into result from booking where booking.id = bookingid;
end;

Jika tidak, Anda harus membuat tipe objek terlebih dahulu, dan memilih beberapa bidang ke dalam tipe objek dan mengembalikannya. Anda harus BUAT OBYEK atau BUAT REKAM.

CREATE OBJECT BOOKING_OBJ AS (
     bookingid INTEGER
    ,booking_name VARCHAR2(128)
);

declare or replace procedure select_row 
(
    bookingid in integer,
    result out BOOKING_OBJ
) as 
begin
    select booking_obj(bookingid, booking_name) into result from booking where booking.id = bookingid;
end;

Atau...

CREATE TYPE BOOKING_REC as record(
    bookingid integer,
    booking_name varchar2(100)
);

declare or replace procedure select_row 
(
    bookingid in integer,
    result out BOOKING_REC
) as 
begin
    select bookingid, booking_name into result from booking where booking.id = bookingid;
end;

Atau, Anda dapat mengembalikan kursor ref.
