--二：测试函数结果集表
select htjs_business_state.* from table(fun_htjs_business_state) htjs_business_state;

--三：创建对应物化视图
drop materialized view mv_htjs_business_state;
create materialized view mv_htjs_business_state refresh force on demand as select htjs_business_state.* from table(fun_htjs_business_state) htjs_business_state;
--1.查询语句：
select * from mv_htjs_business_state;

--四：调用前手动刷新物化视图
--1.pl/sql命令刷新：exec dbms_mview.refresh('mv_htjs_business_state');
--2.java中调用：call dbms_mview.refresh('mv_htjs_business_state')";

--业务状态写法二：
create or replace function fun_htjs_business_state
return htjs_business_row
as
