> In calcite's ParserTest, there is a lack of test for DateFunction. Currently,
> calcite only supports date function from parser.jj:
> date_diff,
> date_trunc.
> It also lacks support for many date functions. For details, you can
> see:[https://dev.mysql.com/doc/refman/8.0/en/date-and-time-functions.html]
> I supported the two functions date_add and date_sub in Parser.jj, and added
> relevant tests about date function in SqlParserTest. The purpose of adding
> this datefunctiontest is to tell us which date functions are supported and
> which date functions are not supported.
