MySQL Command: ADDDATE()

MySQL Command: ADDDATE()

MySQL is a popular open-source relational database management system that is widely used for web applications. It provides a wide range of functions and commands to manipulate and query data efficiently. One such command is ADDDATE(), which allows you to add or subtract a specified interval to a date or datetime value.

Syntax

The syntax for the ADDDATE() command is as follows:

ADDDATE(date, INTERVAL value unit)

Here, date is the date or datetime value to which you want to add the interval, value is the number of intervals to add, and unit is the type of interval (e.g., DAY, MONTH, YEAR, HOUR, MINUTE, SECOND).

Examples

Let's look at some examples to understand how the ADDDATE() command works:

Example 1: Adding Days

SELECT ADDDATE('2022-01-01', INTERVAL 7 DAY);

This query adds 7 days to the date '2022-01-01' and returns the result as '2022-01-08'.

Example 2: Subtracting Months

SELECT ADDDATE('2022-01-01', INTERVAL -3 MONTH);

This query subtracts 3 months from the date '2022-01-01' and returns the result as '2021-10-01'.

Example 3: Adding Hours

SELECT ADDDATE('2022-01-01 12:00:00', INTERVAL 2 HOUR);

This query adds 2 hours to the datetime '2022-01-01 12:00:00' and returns the result as '2022-01-01 14:00:00'.

Usage

The ADDDATE() command is useful in various scenarios, such as:

  • Calculating future or past dates based on a given date
  • Performing date arithmetic in queries
  • Generating reports with date ranges

By using the ADDDATE() command, you can easily manipulate dates and datetimes in your MySQL queries and applications.

Summary

The ADDDATE() command in MySQL allows you to add or subtract a specified interval to a date or datetime value. It is a powerful tool for performing date arithmetic and manipulating dates in your MySQL queries. Whether you need to calculate future dates, subtract months, or add hours, the ADDDATE() command provides a flexible and efficient solution.
