Sample table: employees

SELECT *

WHERE to_char(hire_date,'MON') LIKE '_A%';

Sample Output:

 emp_id | emp_name | job_name | manager_id | hire_date  | salary  | commission | dep_id
--------+----------+----------+------------+------------+---------+------------+--------
  66928 | BLAZE    | MANAGER  |      68319 | 1991-05-01 | 2750.00 |            |   3001
  68736 | ADNRES   | CLERK    |      67858 | 1997-05-23 | 1200.00 |            |   2001
  69324 | MARKER   | CLERK    |      67832 | 1992-01-23 | 1400.00 |            |   1001
(3 rows)

Explanation:

The said query in SQL that returns all rows from the 'employees' table where the second letter of the "hire_date" month is "A", and the month name is three characters long. The "to_char" function converts the "hire_date" column to a string in the format "MON", which returns the abbreviated name of the month.

The underscore "_" symbol is used as a wildcard to match any single character before the "A" character.
