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 'DD', is less than '19'.

The to_char function converts the "hire_date" column to a character string with the format mask 'DD', which means that only the day of the month will be displayed.

The WHERE clause includes only those rows for the day of the hire_date value is less than the 19th day of the month.
