Mysql Comparing Datetime With Timestamps Stack Overflow In practice, mysql converts the datetime column to an integer in the following way: say the datetime column a has value 2021 09 14 15:11:13; when we do select a > 1;, datetime is converted to 20210914151113 implicitly. The best way to compare date and time and get minutes back is probably to use one of the following: select time to sec(timediff(timea,timeb) 0) 60 select timestampdiff(minute,timeb,timea) note that while timediff works with times, timestampdiff requires a date component and the values are switched around for timestampdiff.
Mysql Datetime Comparison Stack Overflow Timestampdiff () is a powerful built in function in mysql that allows you to calculate the difference between two date or datetime expressions. understanding how to leverage this command within mysql 8 can significantly help you in handling time based data, from calculating age to comparing timestamps from various events. This tutorial demonstrates how we can compare mysql timestamp dates with the date parameter only using the date (), cast (), and convert () functions. Choosing between datetime and timestamp depends on the specific requirements of your application. datetime is best for scenarios where timezone independence and long range date support are needed, while timestamp excels in applications requiring automatic updates and timezone aware timestamps. Mysql has the ability to compare two different dates written as a string expression. when you need to compare dates between a date column and an arbitrary date, you can use the date() function to extract the date part from your column and compare it with a string that represents your desired date.

Learn how to effectively compare timestamps in mysql with detailed examples and explanations. In this article, we will learn how to use the mysql timestampdiff () function, which returns the difference between two timestamp values, in a specified unit. Timestamp converts the stored time to utc and converts it back to the current time zone of the mysql server when retrieved. datetime requires 8 bytes of storage. timestamp requires 4 bytes of storage, making it more efficient for saving space. This tutorial will introduce you to datetime and timestamp data types. you will also understand where to use them and what are their similarities and differences.
