oracle如何脱敏

创建脱敏表：
create table tuomintable(TABLE_NAME varchar(50), column_name varchar(50), data_type varchar(50), tuomintype int, needtuomin int);
--truncate table tuomintable;
用业务账套把表的字段信息插入到脱敏表tuomintable：
DECLARE

v_TABLE_NAME    varchar(50);
v_column_name         varchar(50);
v_data_type         varchar(50);
v_tuomintype          number(30);
v_needtuomin         number(30);
v_text2 varchar(1000);
CURSOR c1 IS
select table_name,column_name,data_type,'1' as tuomintype ,'0' as needtuomin from user_tab_columns   ;
BEGIN
OPEN c1;
   LOOP
    FETCH c1
      INTO v_TABLE_NAME, v_column_name,v_data_type, v_tuomintype, v_needtuomin ;
    EXIT WHEN c1%NOTFOUND;
v_text2 := 'insert into tuomintable values ('|| ''''||v_TABLE_NAME ||''''|| ',' ||    ''''||v_column_name||'''' || ',' || ''''||v_data_type||'''' || ',' ||    v_tuomintype ||','||''''|| v_needtuomin||''''||')';
execute immediate v_text2;
DBMS_OUTPUT.PUT_LINE(v_text2);
   END LOOP;
commit;
close c1;
END;
/
把脱敏表tuomintable导入到excel，并对v_tuomintype，字段参照以下信息更改，
如果字段需要脱每， v_needtuomin改成1，否则删除该行，或把v_needtuomin改成0
1 ：名称
11:地址
2 ：证件
3 ：银行账号
4 ：联系电话
5 ：接入号码
12: number数值型，取100～1000之间的随机数
