Sample table: employees

Pictorial Presentation:

Sample Solution:

SELECT *
FROM employees
WHERE to_char(hire_date,'MON') ='APR';

OR

SELECT *
FROM employees
WHERE to_char(hire_date,'MON') IN ('APR');

OR

SELECT *
FROM employees
WHERE to_char(hire_date,'MON') LIKE 'APR%';

Sample Output:

 emp_id | emp_name | job_name | manager_id | hire_date  | salary  | commission | dep_id
--------+----------+----------+------------+------------+---------+------------+--------
  65646 | JONAS    | MANAGER  |      68319 | 1991-04-02 | 2957.00 |            |   2001
  67858 | SCARLET  | ANALYST  |      65646 | 1997-04-19 | 3100.00 |            |   2001
(2 rows)

Explanation:

The said query in SQL that selects all columns from the table 'employees' where the hire_date value, after being converted to a character string with the format mask 'MON', is equal to 'APR'.

The to_char function converts the "hire_date" column to a character string with the format mask 'MON', which means that only the abbreviated month name will be displayed in uppercase letters.

The WHERE clause checks if the hire_date value corresponds to the month of April.
