Description

Allow to generate a sequence of dates by day step in a range of dates. For instance:

spark-sql> select sequence(date'2021-07-01', date'2021-07-10', interval '3' day);
Error in query: cannot resolve 'sequence(DATE '2021-07-01', DATE '2021-07-10', INTERVAL '3' DAY)' due to data type mismatch:
sequence uses the wrong parameter type. The parameter type must conform to:
1. The start and stop expressions must resolve to the same type.
2. If start and stop expressions resolve to the 'date' or 'timestamp' type
then the step expression must resolve to the 'interval' or
'interval year to month' or 'interval day to second' type,
otherwise to the same type as the start and stop expressions.
