jdbc调用存储过程oracle版 返回游标

1.创建

create or replace procedure getLog(record_ref out sys_refcursor,inputId in log201112.id%type)
AS
begin
open record_ref for
    select * from log201112 where id=inputId;
end getLog;
/

2.调用

String procedure="{call getLog(?,?)}";
  CallableStatement cstmt=conn.prepareCall(procedure);//conn为java.sql.Connection对象
  cstmt.registerOutParameter(1, OracleTypes.CURSOR);//oracle驱动包里的类 import oracle.jdbc.OracleTypes;
  cstmt.setInt(2, 2);
  cstmt.execute();
  ResultSet rs=(ResultSet)cstmt.getObject(1);
  while(rs.next()){
      String info=""+rs.getInt("ID");
      info+=rs.getTimestamp("CREATE_TIME");
      System.out.println(info);
   }
