我被困在这里，如果可能的话需要一些指导！

我有这张桌子：

doctor_details (doctor_id, name, surname, date_of_birth)

我只想创建一个程序，以下列形式添加 30 位医生：

doctor_id  name    surname    date_of_birth
-------------------------------------------
01         John-01 Surname-01 2001-01-01
02         John-02 Surname-02 2002-01-01
03         John-03 Surname-03 2003-01-01

我显然知道如何做，但是我需要在这里进行一些迭代以某种方式将其放入程序中，因此当我调用它以立即增加这些行时！

你可以用 1 条 sql 语句来做到这一点。

SQL> create table doctors(doctor_id number, name varchar2(100), surname varchar2(100), date_of_birth date);

Table created.

SQL> create sequence doctor_id_seq start with 1 cache 100;

Sequence created.

SQL> insert into doctors
  2              (doctor_id, name, surname, date_of_birth)
  3  select doctor_id_seq.nextval, 'John-' || doctor_id_seq.currval, 'Surname-' || doctor_id_seq.currval, to_date('01-jan-2001', 'dd-mon-yyyy') + dbms_random.value(1, 3000)
  4    from dual
  5   connect by level <= 30/*rows to gen*/;

30 rows created.

SQL> col name format a20
SQL> col surname format a20
SQL> select * from doctors;

 DOCTOR_ID NAME                 SURNAME              DATE_OF_B

这是经过测试的代码::

 drop table doctor_details;
    create table doctor_details 
    (doctor_id varchar2(20),
     name varchar2(100), 
     surname varchar2(100), 
     date_of_birth date);

    drop sequence doctor_id_seq;
    create sequence doctor_id_seq 
    start with 1 
    maxvalue 99999999
    cache 100;



    alter session set nls_date_format='yyyy-mm-dd hh24:mi:ss';



        create procedure doctors_details_add as
    begin
              for x in 1..30 loop
              insert into doctor_details (doctor_id, name, surname, date_of_birth)
              values
              (lpad(doctor_id_seq.nextval,2,'0'),
               'John'||'-'||lpad(doctor_id_seq.currval,2,'0'),
               'Surname'||'-'||lpad(doctor_id_seq.currval,2,'0'),
                add_months(to_date('2001-01-01','YYYY-MM-DD'),12*doctor_id_seq.currval)
               );
              end loop;
    end doctors_details_add;
