>             Project: Ignite
>          Issue Type: Bug
>          Components: sql
>    Affects Versions: 3.0.0-beta1

> Some queries can`t be correctly processed:
> SELECT MIN(NULL) will throw :
> {code:java}
> Caused by: java.lang.AssertionError: Unexpected type of result: NULL
> 	at org.apache.ignite.internal.sql.engine.util.TypeUtils.columnType(TypeUtils.java:343)
> {code}
> Seems fix is trivial : we need to append additional type into *SqlColumnType*
> {code:java}
>             case NULL:
>                 return Void.class;
> {code}
> and support it into :
> {code:java}
> TypeUtils#columnType
> {code}
