How to Retrieve the Three Nearest Future Events in MySQL?

Query to Retrieve Nearest Future Events

Problem:

Develop a MySQL query that extracts the three most imminent events from a given database, considering their scheduled start dates.

Table Structure:

Column	Data Type
EVENT_ID	Integer
EVENT_NAME	String
EVENT_START_DATE	DATETIME

Sample Data:

EVENT_ID	EVENT_NAME	EVENT_START_DATE
1	test	2011-06-01 23:00:00
2	test2	2011-06-03 23:00:00
3	test3	2011-07-01 23:00:00
4	test4	2011-08-09 23:00:00
5	test5	2011-06-02 23:00:00
6	test6	2011-04-20 23:00:00

Query:

The following query retrieves the three events with the closest future start dates:

SELECT event_id
FROM Table
WHERE EVENT_START_DATE > NOW()
ORDER BY EVENT_START_DATE
LIMIT 3;

Explanation:

• WHERE EVENT_START_DATE > NOW(): Filters out past events by comparing start dates to the current date.
• ORDER BY EVENT_START_DATE: Orders the remaining events by their start dates in ascending order.
• LIMIT 3: Restricts the results to the top three events.

Note:

If events in the past should also be included, remove the WHERE EVENT_START_DATE > NOW() clause.
