Write a Oracle SQL query to get the designations (jobs) along with the total number of employees in each designation. The output should contain only those jobs with more than three employees.

Sample Solution:

Oracle Code :

CREATE TABLE employees (
  EMPLOYEE_ID numeric(6) NOT NULL primary key,
  FIRST_NAME varchar2(20) DEFAULT NULL,
  LAST_NAME varchar2(25) NOT NULL,
  EMAIL varchar2(25) NOT NULL,
  PHONE_NUMBER varchar2(20) DEFAULT NULL,
  HIRE_DATE date NOT NULL,
  JOB_ID varchar2(10) NOT NULL,
  SALARY decimal(8,2) DEFAULT NULL,
  COMMISSION_PCT decimal(2,2) DEFAULT NULL,
  MANAGER_ID numeric(6) DEFAULT NULL,
  DEPARTMENT_ID numeric(4) DEFAULT NULL
);
