Mysql's now() +1 day

Working only with date component

If you're only interested in the date without time, do this:

SELECT CURDATE() + INTERVAL 1 DAY;


With the time part drained, it simply gives tomorrow's date with time set to 00:00:00.

Leap over calendar complexities

Manual date computations? Don't. They're as messy as spilt milk due to month/year transitions:

# Accurate jump from Feb 28 to March 1
SELECT '2022-02-28' + INTERVAL 1 DAY;


Trust the built-in functions. They know leap years and month lengths.

The mighty DATE_ADD function

Feeling overwhelmed with date calculations? Bring out the big gun:

SELECT DATE_ADD(NOW(), INTERVAL 1 DAY);


DATE_ADD makes dates roll over hills and valleys of the calendar like a pro.

Dealing with 'date' and 'data'

Got a column named 'date' or 'data'? Handle with care:

SELECT `date` FROM your_table;


Backticks (`) keep reserved words like 'date' in order. It's like saying "I respect you, keyword."

Column specification in inserts

Specify your columns when doing your inserts:

INSERT INTO your_table (column1, `date`) VALUES ('value1', NOW() + INTERVAL 1 DAY);


It ensures that every value finds its right place. Like socks in their drawer.

Practicing clarity with 'VALUES'

Use the VALUES clause, be clear:

INSERT INTO your_table (column1, `date`) VALUES ('value1', CURDATE() + INTERVAL 1 DAY);


Cleary specifying values inserted is like leaving a note for your future debugging self. They'll thank you.

INTERVAL and UNIT: Tailor-made date arithmetic

The INTERVAL and UNIT give you the power to do date mathematics your own way:

# Want to feel two months older?
SELECT CURDATE() + INTERVAL 2 MONTH;


Easy to understand. Easy to get exactly what you want.

Consultation with the Documentation

Studying the MySQL documentation is like taking a sherpa for your journey up the database mountain.

Syntax precision and error detection

A successful query is like a well-tuned musical instrument, every part perfectly crafted, every note checked.

Case-insensitivity

MySQL is easy-going. It likes DAY, day, or even dAY. It gets you:

# Going to a party tomorrow?
SELECT '2022-12-31' + INTERVAL 1 DaY;
# Remember, no elephants allowed at the party


Dealing with date arithmetic complexities

When doing date arithmetic, remember, MySQL has your back:

# Leap Day? No problem!
SELECT '2022-02-28' + INTERVAL 1 DAY;


Use the built-in functions. Don't punt a calculus book into the time dimension.

Formatting consistency

In MySQL Land, consistency is king. Watch the throne:

# Batman Returns - July 20, 2022
SELECT STR_TO_DATE('07,20,2022', '%m,%d,%Y') + INTERVAL 1 DAY;
# Spoiler: Robin shows up


Consistent date format avoids surprises. Except for movie spoilers.

Real-world SQL operations

Managing billing cycles

Track next billing dates accurately:

UPDATE accounts SET next_billing_date = LAST_DAY(NOW()) + INTERVAL 1 DAY WHERE id = 1;
# So timely even the Ghost of Christmas Yet-to-Come would applaud


Creating reminders and notifications

Get upcoming events. Because human memory isn't always reliable:

SELECT * FROM events WHERE event_date = CURDATE() + INTERVAL 1 DAY;
# Ah, the joy of being prepared


Data analysis and report generation

Generate Day-over-Day comparisons. Because data is gold:

SELECT today_stats.*, yesterday_stats.*
FROM statistics AS today_stats
JOIN statistics AS yesterday_stats ON today_stats.date = yesterday_stats.date + INTERVAL 1 DAY;
# So that you can really appreciate the differences a day makes

