The error is in jaspersoft studio and they are no viable alternative at input 'month' , no viable alternative at input 'year' , missing EOF at '='

Question

I have written SQL query in jaspersoft studio

Select Orderid , Orderdate , Shipcity,   
year(Orderdate) as year, month(Orderdate) as month 
from Orders 
where Orderid IN
(
    SELECT EXTRACT(YEAR FROM Orderdate) , 
          EXTRACT(MONTH FROM Orderdate) 
    from Orders 
    where (
        year(Orderdate) =  Startyear 
        AND
        month(Orderdate) = Startmonth 
    )
)

This is the query

Answer 1

Your SQL, as written, doesn't make a lot of sense. The subquery after

where Orderid IN

needs to return a single field containing order Ids but instead you've written something that returns 2 fields, neither of which appear to be an Order Id
