oracle学习之路（6）两个实际使用的例子

1.简单数据插入例子

-- Created on 2015/6/15 by LYH 
declare 
   v_fnumber varchar2(10):='qwe';
   v_fname varchar2(10):='lyh';
   v_fage int:=10;
   v_fsalary int:=101.00;
begin
  INSERT INTO t_employee(fnumber,fname,fage,fsalary)
  VALUES(v_fnumber,v_fname,v_fage,v_fsalary);

  COMMIT;

end;

2. 简单数据删除例子

-- Created on 2015/6/15 by LYH 
declare 
  v_fnumber varchar2(10):='asd';
  v_fname varchar2(10):='gqy';
  v_fage int:=12;
  v_salary int:=13;

begin
  DELETE FROM t_employee
  WHERE fname='lyh';
  COMMIT;

end;

3.一个修改的例子

-- Created on 2015/6/15 by LYH 
declare 
   v_fnumber varchar2(10):='gqy';
   v_fname varchar2(10):='gqy';
   v_fage int :='12';
   v_fsalary int :='1231231';
begin
  UPDATE t_employee 
  SET fnumber=v_fnumber, fname=v_fname,fage=v_fage,fsalary=v_fsalary
  WHERE fnumber='000000';


end;
