oracle快速构造数据

新建存储过程

create or replace procedure generate_data(tbl_name varchar,min_value int, max_value int) is
    MAX_NUM integer := max_value;
    MIN_NUM integer := min_value;
    tmp_val varchar2(100):='';
BEGIN
    for i in MIN_NUM..MAX_NUM
    loop
        tmp_val:='u'||i;
        execute immediate 'insert into '||tbl_name ||' values(:1, :2)' using i,tmp_val;  --insert语句末尾不能有分号，否则出错
    end loop;
    commit;
END;

• 建表

create table test0(id int, name varchar2(100));

• 调用存储过程，生成数据

begin
    generate_data('test0',1,10000000);
end; 

• 新建其他表

create table test1 as select * from test0;
create table test2 as select * from test0;
create table test3 as select * from test0;
create table test4 as select * from test0;
create table test5 as select * from test0;
create table test6 as select * from test0;
create table test7 as select * from test0;
create table test8 as select * from test0;
create table test9 as select * from test0;
