如果以PREBUILD方式建立物化视图，除非指定了WITH REDUCED PRECISION语句(在on prebuilt table后面加上with reduced precision就可以了)，否则列的精度必须满足SELECT表达式的精度；
--1.在ods用户下创建表，删表空间，主键，添加lastmodifydate 默认系统时间，注释
create table FPGL_FPXX
(
id VARCHAR2(32) not null,
fplx VARCHAR2(3),
sksbbh VARCHAR2(32),
kpzdbs VARCHAR2(32),

--2.在ods用户下改表名
ALTER TABLE FPGL_FPXX RENAME to HX_FPGL_FPXX;
--3.在ods用户下创建物化视图（如果不加with reduced precision，就会报错误：ora-12060:预建表的形式与定义查询不匹配，但是有时候不加也不报错，那是因为建表的时候没有指定类似于这样的精度(VARCHAR2(16 CHAR))）

--4.在ods触发器
CREATE OR REPLACE TRIGGER TG_HX_FPGL_FPXX
---进行更新操作时候
BEFORE UPDATE ON HX_FPGL_FPXX
---任何一行
FOR EACH ROW
BEGIN
----将修改时间插入datadate中
:NEW.LastModifyDate := SYSDATE;
END;
--5.全量刷新物化视图（C是全量，F是增量）
call dbms_mview.refresh('HX_FPGL_FPXX','C');
--6.创建主键，表空间
alter table HX_FPGL_FPXX
add constraint PK_HX_FPGL_FPXX primary key (ID)
using index
