> Here is the example of the query:

> {code}
> Ignite is not aware of the alias and incorrectly appends the SELECT statement, which causes this exception:

> Exception in thread "main" javax.cache.CacheException: Failed to parse query: SELECT "CacheQueryExamplePersons".Person._key, "CacheQueryExamplePersons".Person._val from Person p where salary > ? and salary <= ?
