MySQL DATE_ADD () function

MySQL DATE_ADD () function I always think that the DATE_ADD () function is unreasonable and misleading others, because it is not only about the increase of dates, but also I often use it for subtraction. Is it better to change to DATE_CHANGE? :) Define and use the DATE_ADD () function to add a specified interval to a date. Usage: The [SQL] DATE_ADD (date, INTERVAL expr type) date parameter is a valid date expression. The expr parameter is the time interval you want to add. Type indicates the type. The type parameter can be the following values: Type value, for example, [SQL] DATE_ADD (# BIZ_DATE #, INTERVAL-1 DAY). Here # BIZ_DATE # Minus one DAY
