How can I add days to a date in MYSQL in a query
I am trying to add 5 days to a date in MYSQL in a query. This is what I have done:
SELECT * FROM sales INNER JOIN partner on user_id = idpartner WHERE DATE((end_date) + 5) >= DATE(NOW()) ORDER BY end_date ASC LIMIT 0,50000
But this is not showing the list of sales which has ended. Can someone please tell me where I am making a mistake.
It looks like you want rows where
end_date is later than five days ago.
The best way to get that is with
WHERE end_date >= CURDATE() - INTERVAL 5 DAY
The business of adding integers to dates doesn't work in MySQL (it's an Oracle thing). So you need to use the
INTERVAL n unit syntax.
You'll notice that my WHERE clause above is functionally equivalent to
WHERE DATE(end_date) + INTERVAL 5 DAY >= DATE(NOW())
But, the first formulation is superior to the second for two reasons.
- if you mention
end_datein a WHERE clause without wrapping it in computations, your query can exploit an index on that column and can run faster.
CURDATE()both refer to the first moment of today (midnight). But
CURDATE()is a bit simpler.
MySQL add days to a date, MySQL add days to a date? INSERT INTO yourTableName VALUES(DATE_ADD(now(),interval n day)); In the above syntax, you can use curdate() instead of now().

This is what I have done: SELECT * FROM sales INNER JOIN partner on user_id = idpartner WHERE DATE((end_date) + 5) >= DATE(NOW()) ORDER BY end_date ASC LIMIT 0,50000 But this is not showing the list of sales which has ended.
To fix the original query, you can use DATE_ADD with the INTERVAL keyword:
SELECT * FROM sales INNER JOIN partner ON user_id = idpartner WHERE DATE_ADD(end_date, INTERVAL 5 DAY) >= DATE(NOW()) ORDER BY end_date ASC LIMIT 0 , 50000
Said that, I wouldn't recommend applying functions such as DATE_ADD on columns, as it means that the database won't be able to use an index on end_date. Therefore, I would modify the query to:
SELECT * FROM sales INNER JOIN partner ON user_id = idpartner WHERE end_date <= DATE_ADD(DATE(NOW()), INTERVAL 5 DAY) ORDER BY end_date ASC LIMIT 0 , 50000
As you can see, in the second alternative all functions are applied on constants and not on columns (
