How to Add One Year to a Date Field in MySQL?

Updating Date Fields in MySQL: Adding One Year

In MySQL, updating numerical values by increments can be achieved using the number=number 1 syntax. However, when working with date fields, a different approach is required to add a specific duration.

Adding One Year to a Date Field:

To increment a date field by one year, you can use the DATE_ADD function (or ADDDATE with INTERVAL). This function allows you to add a specified interval to a given date:

UPDATE table SET date = DATE_ADD(date, INTERVAL 1 YEAR) 
Copy after login

This statement will add one year to the date field for all rows in the specified table. The INTERVAL clause specifies the amount and unit of time to add, in this case, 1 YEAR.

Example:

Suppose you have a table named events with a column called event_date containing dates. To update all events and move them forward by one year, you would use the following query:

<code class="sql">UPDATE events SET event_date = DATE_ADD(event_date, INTERVAL 1 YEAR);</code>
Copy after login

After executing this query, all event dates in the table will be increased by one year.
