Oracle custom data type question

Problem description

I learned it today Oracle Custom data types in TYPE, After inserting data , The field value is displayed as user name .TYPE name （ value 1, value 2）, Instead of （ value 1, value 2）

-- establish TYPECREATE OR REPLACE TYPE type_name AS OBJECT （   FirstName varchar(100),  LastName varchar(100),）-- Create table CREATE TABLE STUDENT(  ID NUMBER(10),  NAME type_name,  SEX VARCHAR(10))-- insert data INSERT INTO STUDENT(ID,NAME,SEX) VALUES(11,type_name(' Zhang ',' 3、 ... and '),' male ');INSERT INTO STUDENT(ID,NAME,SEX) VALUES(12,type_name(' Li ',' Four '),' male ');

doubt

I thought “NAME” It will show (' Zhang ',' 3、 ... and '), The result now shows "WMS_LP_ZHONGCHE"."TYPE_NAME"(' Zhang ',' 3、 ... and '), Is this normal ？

And I use this field to fuzzy query , Has been an error , I tried for a long time but failed

Precise query can
