DATEDIFF
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
Subtract two SQL DATE types (represented by java.sql.Date).
This function comes in two flavours:
MySQL 2 argument version
In MySQL, there is a 2 argument verison of the DATEDIFF() function, where the result produces the number of days between the two dates. The argument order is in the order of the difference notation: end_date - start_date
SELECT DATEDIFF( DATE '2020-02-03', DATE '2020-02-01');
create.select(dateDiff(
Date.valueOf("2020-02-03"),
Date.valueOf("2020-02-01"))).fetch();
The result being
+------------+ | datediff | +------------+ | 2 | +------------+
