JAVA存储过程和调用

代码内容
create or replace procedure batchUpdateCustomer(p_age in number) as
begin
update CUSTOMERS set AGE=AGE+1 where AGE>p_age;
end;
以上存储过程有一个参数p_age，代表客户的年龄，应用程序可按照以下方式调用存储过程：
代码内容
tx = session.beginTransaction();
Connection con=session.connection();
String procedure = "{call batchUpdateCustomer(?) }";
CallableStatement cstmt = con.prepareCall(procedure);
cstmt.setInt(1,0); //把年龄参数设为0
cstmt.executeUpdate();
tx.commit();
create or replace produre batchUpdateStudent(a in number) as
begin
update STUDENT set AGE=AGE+1 where AGE>a;
end;
调用代码如下：
Transaction tx=session.beginSession();
Connection conn=session.connection();
String pd=”...{call batchUpdateStudent(?)}”;
CallableStatement cstmt=conn.PrepareCall(pd);
cstmt.setInt(1,20); //把年龄这个参数设为20
tx.commit()；
