How to get today -“1 day” date in sparksql?

Question

How to get current_date - 1 day in sparksql, same as cur_date()-1 in mysql.

Answer 1

Yes, the date_sub() function is the right for the question, anyway, there's an error in the selected answer:

Return type: timestamp

The return type should be date instead, date_sub() function will trim any hh:mm:ss part of the timestamp, and returns only a date.
