Evgeny Stanilovsky updated IGNITE-18361:
----------------------------------------
Description:
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}
