【Oracle/PLSQL】没事玩一个简单的表充值程序

create table emp2(
id number,
name nvarchar2(20),
salary number(5),
primary key(id));

begin
for i in 1..10000 loop
    insert into emp2 values(i,dbms_random.string('*',dbms_random.value(6,20)),dbms_random.value(3000,99999));
end loop;

commit;

end;
/

SQL> create table emp2(
  2  id number,
  3  name nvarchar2(20),
  4  salary number(5),
  5  primary key(id));

表已创建。

SQL> begin
  2  for i in 1..10000 loop
  3      insert into emp2 values(i,dbms_random.string('*',dbms_random.value(6,20)),dbms_random.value(3000,99999));
  4  end loop;
  5
  6  commit;
  7
  8  end;
  9  /

PL/SQL 过程已成功完成。

SQL> select count(*) from emp2;

  COUNT(*)
----------
     10000

SQL> select avg(salary) from emp2;

AVG(SALARY)
-----------
   51678.82
