Object Types in Oracle

 Object Types in Oracle

Object types are user-defined data types that can be used to store complex data structures. Object types are used to create custom data structures that can be used in SQL queries and PL/SQL code. Here is an example:

CREATE TYPE person_t AS OBJECT (

   first_name VARCHAR2(50),

   last_name VARCHAR2(50),

   email VARCHAR2(100),

   birth_date DATE

);

This creates an object type named "person_t" that defines a custom data structure for a person, including their first name, last name, email, and birth date.
