Pictorial Presentation:

Sample Solution:

SELECT *
FROM employees
WHERE to_char(hire_date, 'mon')='jan';

Sample Output:

 emp_id | emp_name | job_name | manager_id | hire_date  | salary  | commission | dep_id
--------+----------+----------+------------+------------+---------+------------+--------
  69324 | MARKER   | CLERK    |      67832 | 1992-01-23 | 1400.00 |            |   1001
(1 row)

Explanation:

The said query in SQL that selects all columns and rows from the 'employees' table where the month of the hire date is January.

The "to_char" function converts the "hire_date" column to a string representation of the month using the 'mon' format. The comparison operator '=' is then used to compare this string to the string 'jan'.
