错误出现在 jaspersoft studio 中，它们在输入 'month' 时没有可行的替代方案，在输入 'year' 时没有可行的替代方案，在 '=' 处缺少 EOF

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
