How Can I Increment Dates in MySQL?

Modifying Date Fields in MySQL: Incrementing Date Values

In MySQL, you can easily update numerical fields by incrementing them using syntax like UPDATE table SET number=number 1. However, when it comes to date fields, the process is slightly different.

Adjusting a Date Field by One Year

To add one year to a date field, you can utilize the DATE_ADD function. This function takes two arguments: a date field and a time interval. To increment the date by one year, use an interval of INTERVAL 1 YEAR.

The following query demonstrates this:

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

This query will add one year to the date field in the specified table. Note that the date field should be in a valid date format.
