MySQL Timestamp Query Methods: Complete Guide

In MySQL, you can use the UNIX_TIMESTAMP function to convert date time to a timestamp, or you can use the FROM_UNIXTIME function to convert a timestamp to date time.

Here are some common methods for querying timestamps in MySQL:

1. Convert the date and time to a timestamp.

SELECT UNIX_TIMESTAMP('2022-01-01 00:00:00');

1. Convert a timestamp to a date and time.

SELECT FROM_UNIXTIME(1640995200);

1. Check the current timestamp.

SELECT UNIX_TIMESTAMP(NOW());

1. Check the current date and time:

SELECT FROM_UNIXTIME(UNIX_TIMESTAMP(NOW()));

1. Get the timestamp of a specific date and time.

SELECT UNIX_TIMESTAMP('2022-01-01 00:00:00');

1. Retrieve the date and time of a specific timestamp.

SELECT FROM_UNIXTIME(1640995200);

These methods make it easy to convert and query timestamps in a MySQL database.
