What is DATEADD() Function?
DATEADD() helps to add a specific value for the date or time part. For example,If I want to get a specific date after 150 days from the present date then we can use this function, which will get the exact output date.

- The units are used is a Date part ( year, month, date ) or Time part (hours, minute, second) only relevant parts will be used.
- Example :

- Minute uses the hour and minutes from the time/timestamp.

What is the syntax of the DATEADD() function in Snowflake?
-- Syntax : DATEADD ( Date_or_time_part, Value, Expression)
DATEADD() Argument Details :
|Date_or_time_part||The unit value ( Mandatory )|
|Value||Number ( Mandatory )|
|Expression||Date or Time Expression ( Mandatory )|
This argument indicates the units of time that we want to add. Let us say if you want to add 2 days, then the unit will be the day.
This is the number of units that you wanted to add. For example, you want to add two months, then it will be two.
Expression evaluates to a date, time, or timestamp. This is the main source to which we will add the day, month, or time.
- If Expression is Time, then it returns time data type.
- If Expression is Timestamp, then it returns timestamp data type.
- If Expression is Date, then it returns Date data type.
Examples of DateAdd() in Snowflake:
select to_date('2014-05-08') as v1, dateadd(year, 3, to_date('2014-05-08')) as v; +------------+------------+ | V1 | V | |------------+------------| | 2014-05-08 | 2017-05-08 | +------------+------------+ select dateadd(month, 1, '2002-01-31'::date) as different_day; +---------------+ | DIFFERENT_DAY | |---------------| | 2002-02-28 | +---------------+
When you should use DATEADD() Function in Snowflake?
