Scenario : in order to group the records with same ID , I tried using group by query but eventually it isn't getting executed.

I don't see any error message, but the query fails to execute with blank.

Query :

SELECT COUNT (customerID), Country FROM Customers GROUP BY Country;

but on Apache , i dont see this issue. please help as this is impacting our production
