oracle怎么执行包的存储过程

oracle如何执行包的存储过程
现有包
CREATE OR REPLACE PACKAGE PKG_AllConsumeBlock is
  TYPE myrctype IS REF CURSOR; 
  PROCEDURE usp_AllConsumeBlock(cur_out OUT myrctype,StartMth char,FinishiMth char);
end PKG_AllConsumeBlock;

包体
CREATE OR REPLACE PACKAGE BODY PKG_AllConsumeBlock AS  
  PROCEDURE usp_AllConsumeBlock
  (
  cur_out OUT myrctype,StartMth char,FinishiMth char
  )
  IS
  BEGIN
OPEN cur_out FOR
  SELECT * from 表名 where 条件 ;
  END usp_AllConsumeBlock;  
END PKG_AllConsumeBlock;

请问该如何调用来进行查询？谢谢各位了
