如果你想插入一些随机值，你可以使用循环插入。

BEGIN 
    FOR x IN 1 .. 1000 LOOP
         INSERT INTO MULTI_INSERT_DEMO (ID, NAME)
         SELECT x, 'anyName' FROM dual;
    END LOOP;
END;

使用SQL *加载程序。这需要一点设置，但如果这不是唯一的，它是值得的。

创建表

SQL> create table ldr_test (id number(10) primary key, description varchar2(20));
Table created.
SQL>

创建CSV

oracle-2% cat ldr_test.csv
1,Apple
2,Orange
3,Pear
oracle-2% 

创建Loader控制文件

oracle-2% cat ldr_test.ctl 
load data

 infile 'ldr_test.csv'
 into table ldr_test
 fields terminated by "," optionally enclosed by '"'              
 ( id, description )

oracle-2% 

执行SQL*Loader命令

oracle-2% sqlldr <username> control=ldr_test.ctl

确认插入

SQL> select * from ldr_test;

        ID DESCRIPTION

         1 Apple
         2 Orange

SQL*Loader有很多选项，并且可以将几乎任何文本文件作为输入。如果需要，您甚至可以将数据内联到控制文件中。

这里有一个页面，有更多的细节-> SQL*Loader

下面是一个非常有用的在Oracle中插入多行的指南:

最后一步:

INSERT ALL
/* Everyone is a person, so insert all rows into people */
WHEN 1=1 THEN
INTO people (person_id, given_name, family_name, title)
VALUES (id, given_name, family_name, title)
/* Only people with an admission date are patients */
WHEN admission_date IS NOT NULL THEN
INTO patients (patient_id, last_admission_date)
VALUES (id, admission_date)
/* Only people with a hired date are staff */
WHEN hired_date IS NOT NULL THEN
INTO staff (staff_id, hired_date)
VALUES (id, hired_date)
  WITH names AS (
    SELECT 4 id, 'Ruth' given_name, 'Fox' family_name, 'Mrs' title,
           NULL hired_date, DATE'2009-12-31' admission_date
    FROM   dual UNION ALL
    SELECT 5 id, 'Isabelle' given_name, 'Squirrel' family_name, 'Miss' title ,
           NULL hired_date, DATE'2014-01-01' admission_date
    FROM   dual UNION ALL
    SELECT 6 id, 'Justin' given_name, 'Frog' family_name, 'Master' title,
           NULL hired_date, DATE'2015-04-22' admission_date
    FROM   dual UNION ALL
    SELECT 7 id, 'Lisa' given_name, 'Owl' family_name, 'Dr' title,
           DATE'2015-01-01' hired_date, NULL admission_date
    FROM   dual
  )
  SELECT * FROM names

每当我需要这样做的时候，我用一个本地过程构建一个简单的PL/SQL块:

declare
   procedure ins
   is
      (p_exch_wh_key INTEGER, 
       p_exch_nat_key INTEGER, 
       p_exch_date DATE, exch_rate NUMBER, 
       p_from_curcy_cd VARCHAR2, 
       p_to_curcy_cd VARCHAR2, 
       p_exch_eff_date DATE, 
       p_exch_eff_end_date DATE, 
       p_exch_last_updated_date DATE);
   begin
      insert into tmp_dim_exch_rt 
      (exch_wh_key, 
       exch_nat_key, 
       exch_date, exch_rate, 
       from_curcy_cd, 
       to_curcy_cd, 
       exch_eff_date, 
       exch_eff_end_date, 
       exch_last_updated_date) 
      values
      (p_exch_wh_key, 
       p_exch_nat_key, 
       p_exch_date, exch_rate, 
       p_from_curcy_cd, 
       p_to_curcy_cd, 
       p_exch_eff_date, 
       p_exch_eff_end_date, 
       p_exch_last_updated_date);
   end;
begin
   ins (1, 1, '28-AUG-2008', 109.49, 'USD', 'JPY', '28-AUG-2008', '28-AUG-2008', '28-AUG-2008'),
   ins (2, 1, '28-AUG-2008', .54, 'USD', 'GBP', '28-AUG-2008', '28-AUG-2008', '28-AUG-2008'),
   ins (3, 1, '28-AUG-2008', 1.05, 'USD', 'CAD', '28-AUG-2008', '28-AUG-2008', '28-AUG-2008'),
   ins (4, 1, '28-AUG-2008', .68, 'USD', 'EUR', '28-AUG-2008', '28-AUG-2008', '28-AUG-2008'),
   ins (5, 1, '28-AUG-2008', 1.16, 'USD', 'AUD', '28-AUG-2008', '28-AUG-2008', '28-AUG-2008'),
   ins (6, 1, '28-AUG-2008', 7.81, 'USD', 'HKD', '28-AUG-2008', '28-AUG-2008', '28-AUG-2008');
end;

如果你想插入一些随机值，你可以使用循环插入。

BEGIN 
    FOR x IN 1 .. 1000 LOOP
         INSERT INTO MULTI_INSERT_DEMO (ID, NAME)
         SELECT x, 'anyName' FROM dual;
    END LOOP;
END;

游标也可以使用，尽管它效率很低。 下面的stackoverflow帖子讨论了游标的用法:
