How do I convert a LocalDate to a java.sql.Date?
Attempt:
Record r = new Record();
LocalDate date = new Date(1967, 06, 22);
r.setDateOfBirth(new Date(date));
This fails (won't compile) and all I can find is Joda time stuff.
I'm using Java 8

The answer is really simple;
import java.sql.Date;
...
LocalDate locald = LocalDate.of(1967, 06, 22);
Date date = Date.valueOf(locald); // Magic happens here!
r.setDateOfBirth(date);
If you would want to convert it the other way around, you do it like this:
Date date = r.getDate();
LocalDate localD = date.toLocalDate();
r is the record you're using in JOOQ and .getDate() is the method for getting the date out of your record; let's say you have a date column called date_of_birth, then your get method should be called getDateOfBirth().

If you want current date:
Date date = Date.valueOf(LocalDate.now());
If you want a specific date:
Date date = Date.valueOf(LocalDate.of(1967, 06, 22));
回答3:
Have you tried using the toDate() method of LocalDate?
As in:
Record r = new Record();
LocalDate date = new Date(1967, 06, 22);
r.setDateOfBirth(date.toDate());
In general, it is a good idea to specify how it fails rather than just say "it fails".
