MySQL date_add () function

In fact, I always think that the date_add () function is unreasonable and misleading others, because it is not only about the increase of dates, but it is often used for subtraction. Is it better to change to date_change? :)

Definition and usage
The date_add () function adds a specified interval to a date.

Usage:

 

DATE_ADD(date,INTERVAL expr type)

The 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 of the following values:

 

Type Value
Microsecond
Second
Minute
Hour
Day
Week
Month
Quarter
Year
Second_microsecond
Minute_microsecond
Minute_second
Hour_microsecond
Hour_second
Hour_minute
Day_microsecond
Day_second
Day_minute
Day_hour
Year_month

 

 

For example:

 

DATE_ADD(#BIZ_DATE#,INTERVAL -1 DAY)

# Biz_date # Minus one day
