PrestoDB translator - 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: Kylin Soong Fix For: 9.2.1 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} SELECT IntKey, ShortValue FROM BQT1.SmallA WHERE BQT1.SmallA.ShortValue IN (SELECT ShortValue FROM BQT1.SmallB) {code} {code:plain|title=\[2\] Exception} org.teiid.jdbc.TeiidSQLException: TEIID30504 Remote org.teiid.core.TeiidProcessingException: TEIID30504 Source: Unexpected exception while translating results: Query failed (#20170110_072908_00117_gftb8): NULL values are not allowed on the probe side of SemiJoin operator.
