Description

https://spark.apache.org/docs/3.5.2/sql-ref-functions-builtin.html#date-and-timestamp-functions

> SELECT date_add('2016-07-30', 1);
 2016-07-31

Currently, date_add supports the addition of year, month, day and other types, but in Spark, only day date type is supported.

date_add(start_date, num_days)	Returns the date that is `num_days` after `start_date`.

The start_date type is the same as the case start_date type in https://issues.apache.org/jira/browse/CALCITE-6396
The num_days type is the day type of date
