To use a defined record in Oracle, you need to follow these steps:

  1. Declare the record type: You can declare a record type using the TYPE statement. For example:
1
2
3
4
5
TYPE employee_record IS RECORD (
   emp_id NUMBER,
   emp_name VARCHAR2(50),
   emp_salary NUMBER
);


  1. Declare a variable of the record type: You can declare a variable of the record type using the DECLARE statement. For example:
1
emp_record employee_record;


  1. Assign values to the record fields: You can assign values to the fields of the record using the assignment operator :=. For example:
1
2
3
emp_record.emp_id := 1;
emp_record.emp_name := 'John Doe';
emp_record.emp_salary := 50000;


  1. Use the record in SQL queries or PL/SQL blocks: You can use the record variable in SQL queries or PL/SQL blocks just like any other variable. For example:
1
2
3
SELECT emp_record.emp_id, emp_record.emp_name
FROM employees
WHERE emp_record.emp_salary > 40000;


By following these steps, you can effectively use a defined record in Oracle.
