前两天改了一个小的无参存储过程，以至于差点忽略掉参数的重要性，今天改了一个大约700行的存储过程，本身有参数传入并计算出返回值，感受到参数的重要性，这次分享下含参存储过程的学习总结；
含参存储过程结构：
create or replace procedure A(B in varchar,C out integer,D out SYS_REFCURSOR)
as V_B
begin
end;
这里我定义了存储过程A的三个参数B C D，由之前经验分享得知，B是只能传出，不会传出，C D 是传出参数，不能传入；
此次我遇到的问题是线上传一个字符串，要通过存储过程解析求得值并反馈回字段；
所以存储过程写了一个B的in类型接字符串值，B拿到值后，通过变量的赋值的形式附到变量上去计算，最后同步变量计算赋值到返回类型的C 和D上进行返回值处理，原存储过程如下：
CREATE OR REPLACE PACKAGE BODY COMMON_QUERY_3 IS
PROCEDURE GET_MERCHANT_ORDER_LIST(INDATA IN VARCHAR2
,TOTAL OUT INTEGER
,OUTDATA OUT SYS_REFCURSOR) AS
I INTEGER;
V_MYVALS MYARRAY; --查询条件
V_ONEVALS MYARRAY;
V_MYSQL VARCHAR2(30000); --返回用
V_SQLCOUNT VARCHAR2(30000); --统计用
V_PAGEINDEX INTEGER DEFAULT 1; --页码
V_PAGESIZE INTEGER DEFAULT 10; --每页条数
V_CONDITION VARCHAR2(5000); --查询列表集用
V_CONDITION_SPLIT VARCHAR2(5000); --查询拆分订单用
V_START_RN INTEGER; --起始数据rownumber
V_END_RN INTEGER; --结束数据rownumber
V_ISEXP INTEGER; --是否为导出需求
V_MERCHANTID INTEGER;
