SQL Datetime Functions

SQL datetime functions are built-in functions in SQL databases that manipulate and extract information from date and time data types. They allow developers to perform operations such as formatting dates, calculating intervals, extracting components (like year or month), and converting between time zones. These functions are essential for handling temporal data in queries, reports, and applications.

Also known as: Date Functions, Time Functions, Datetime Operations, Temporal Functions, SQL Date/Time

Why learn SQL Datetime Functions?

Developers should learn SQL datetime functions when working with databases that store date or time information, such as in e-commerce, logging, scheduling, or analytics applications. They are crucial for tasks like filtering records by date ranges, generating time-based reports, calculating ages or durations, and ensuring data consistency across different time zones. Mastery of these functions improves query efficiency and accuracy in temporal data manipulation.
