MySQL select all rows from this year to a specific month from last year

Jin Anonuevo :

I'm creating a system for a school that needs to retrieve data from April of this year to June from last year.

I needed a query that can retrieve from this dates due to their school year always starts from June and end in April.

I tried selecting dates using Where clause.

"SELECT * FROM students WHERE year(c_date) = ? AND month(c_date) = ? AND c_occupation = 'Student'"

the question marks are use for java language which to prepare a statement using this code

pst=conn.prepareStatement(Sql);
            pst.setInt(1, year);
            pst.setInt(2, month);

I also tried this method but with this, I need to enter the date again after a year has pass.

SELECT users.* FROM users 
WHERE dateadded <= '2019-06-01' 
AND dateadded >= '2018-4-30'

I wanted it to automatically based on what today's year is.

So for example today is March 20, 2019. I should be able to return all the values from this day until June 1, 2018

Your code can be :

LocalDate from = LocalDate.now().minusYears(1); // 2018-04-29
LocalDate to = LocalDate.of(Year.now().getValue(), Month.JUNE, 1); // 2019-06-01

String sql = "SELECT * FROM students WHERE dateadded BETWEEN ? AND ? AND c_occupation = 'Student'";
pst = conn.prepareStatement(Sql);
pst.setObject(1, from);
pst.setObject(2, to);

---

• LocalDate.now().minusYears(1); return the same day of last year
• LocalDate.of(Year.now().getValue(), Month.JUNE, 1); return the 1st June of the current year
• dateadded BETWEEN ? AND ? will select all between the from and to dates
• pst.setObject(1, from); if you are using JDBC 4+ you can set a LocalDate like so
