             Summary: SQL: UPDATE of second level fields fails if parent field was set to null previously
                 Key: IGNITE-10939
                 URL: https://issues.apache.org/jira/browse/IGNITE-10939
             Project: Ignite
          Issue Type: Bug
          Components: sql
            Reporter: Pavel Kuznetsov


Given table in the cache Integer -> Value
{code:java}
static final class Value implements Serializable {
        @QuerySqlField
        Long longCol;

        /**  Inner type object. */
        @QuerySqlField
        InnerType innerTypeCol;

        static final class InnerType implements Serializable {
            @QuerySqlField
            Long innerLongCol;

            @QuerySqlField
            String innerStrCol;
        }
    }
{code}

We insert so data, to have {{innerTypeCol}} in default value null:
{code:sql}
INSERT INTO Value (_key, longCol) VALUES (42, 123);
{code}

Updates of the inner fields {{innerLongCol}} and {{innerStrCol}} 
{code:sql}
UPDATE AllTypes SET innerLongCol = 3
{code}
will result to error:

1) Error message doesn't reflect what have happened
2) In my opinion, in this case we should set innerTypeCol to {{new InnerType {innerLongCol=3, innerStrCol=default} }}
