How to use Comparison Operators In SQL
The other alternative is to use comparison operators like >= (greater than or equal to) and <= (less than or equal to) in order to declare the same thing.
Syntax:
SELECT * FROM table_name WHERE date_column >= 'start_date' AND date_column <= 'end_date';
This method explicitly specifies the boundaries of the date range.
Example: Query achieves the same result as the previous one, using comparison operators instead of BETWEEN
SELECT * FROM events WHERE event_date >= '2023-02-01' AND event_date <= '2023-04-30';
Output:
Explanation: Hence, this query following column “events” shows all the events which happens between Feb 1, 2023 and April 30, 2023.
