Spark SQL provides quite a few functions we can use to add days, months or years to a date or timestamp. These functions include
date_add, date_sub, add_months, etc. These functions can also be used to subtract days, months or years from a date.The following are the examples.
Add days
spark-sql> select date_add(DATE'2022-06-01', 1); 2022-06-02
Subtract days
spark-sql> select date_add(DATE'2022-06-01', -1); 2022-05-31 spark-sql> select date_sub(DATE'2022-06-01', 2); 2022-05-30
Add months
spark-sql> select add_months(DATE'2022-06-01',1); 2022-07-01
Substract months
spark-sql> select add_months(DATE'2022-06-01',-2); 2022-04-01
Add years
There is no direct function we can use but we can use add_months. For example, adding one year is equivalent to add 12 months.
spark-sql> select add_months(DATE'2022-06-01',12) as add_one_year, add_months(DATE'2022-06-01',24) as add_two_years; 2023-06-01 2024-06-01
Subtract years
spark-sql> select add_months(DATE'2022-06-01',-12); 2021-06-01
