> Sql. Unexpected type of result: NULL
> ------------------------------------
>
> Key: IGNITE-18361
> URL: https://issues.apache.org/jira/browse/IGNITE-18361
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Affects Versions: 3.0.0-beta1
> Reporter: Evgeny Stanilovsky
> Priority: Major
> Labels: ignite-3
>
> 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}
