             Summary: PrestoDB tranlator - NULL values not supported in SemiJoin
                 Key: TEIID-4694
                 URL: https://issues.jboss.org/browse/TEIID-4694
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 8.12.8.6_3
            Reporter: Juraj Duráni
            Assignee: Steven Hawkins


PrestoDB does not allows NULL values in SemiJoin operator. It means, that query like \[1\] causes an exception \[2\]. However, this is disallowed in version 0.162 but worked in 0.161. According to GitHub issues \[3\], this will be fixed in one of the future versions of PrestoDB. Do we want to handle it somehow?
Development and release frequency of PrestoDB seems to be pretty fast (new release every 2 or 3 week).

{code:sql|title=\[1\] Query}
