Extract the DAY value from a datetime value.
The DAY function is a short version of the EXTRACT, passing a DatePart.DAY value as an argument.
SELECT day(DATE '2020-02-03');
create.select(day(Date.valueOf("2020-02-03"))).fetch();
The result being
+-----+ | day | +-----+ | 3 | +-----+
Dialect support
This example using jOOQ:
day(Date.valueOf("2020-02-03"))
