jdbc学习：建立数据库表以及存储过程等

jdbc学习过程中的一些数据库操作。

--创建用户表.
create table wangcc_user( id number(10), name binary(30), birthday date, salary number(10,3), primary key(id) );
insert into wangcc_user values(1,'kobe',to_date('1978-08-23','yyyy-mm-dd'),20000.1);
select * from wangcc_user;
create sequence u_seq minvalue 1 maxvalue 99999999 start with 1 increment by 1 nocache nocycle ---触发器 create or replace trigger trg_inert_id before insert on wangcc_user for each row begin select u_seq.nextval into:new.id from dual;
   end;
   insert into wangcc_user(name,birthday,salary) values('james',to_date('1978-08-23','yyyy-mm-dd'),20000.1);
   ----存储过程
create or replace procedure getname( u_id in number, u_name out varchar2 ) As begin select name into u_name from wangcc_user where id=u_id;
  end getname;

select * from wangcc_user;
-----创建一个游标
--建立一个返回游标 
CREATE OR REPLACE PACKAGE PKG_PUB_UTILS IS --动态游标 TYPE REFCURSOR IS REF CURSOR;  
END PKG_PUB_UTILS; 
---创建一个存储过程
create or replace procedure u_getsalary ( ret_code out number, ret_msg out varchar2, ret_cur out PKG_PUB_UTILS.refcursor, in_salary in number ) is begin ret_code:=0;
  ret_msg:='操作成功';
  open ret_cur for
  select * from wangcc_user where salary<in_salary;
  exception
    when others then
      ret_code:=1;
      ret_msg:='错误代码:' || SQLCODE || CHR(13) || '错误信息:' || SQLERRM;  
      end u_getsalary;
      --创建函数：f_get_salary
      create or replace function f_get_salary(v_salary in number) return pkg_test.refcursor is stock_cursor pkg_test.refcursor;
      begin open stock_cursor for select * from wangcc_user where salary<v_salary;
        return stock_cursor;
        end;
