[jira] [Resolved] (CALCITE-4293) cassandra adapter returns null
when selecting non-null tuple elements
[ https://issues.apache.org/jira/browse/CALCITE-4293?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alessandro Solimando resolved CALCITE-4293.
-------------------------------------------
Resolution: Not A Bug
This is not a bug since struct fields must be accessed via the DOT operator, while the ticket example features ITEM operator.
The corresponding version of the proposed unit test is passing correctly:
{code:java}
@Test void testTupleInnerValues() {
CalciteAssert.that()
.with(DTCASSANDRA)
.query("select \"test_collections\".\"f_tuple\".\"1\","
+ "\"test_collections\".\"f_tuple\".\"2\","
+ "\"test_collections\".\"f_tuple\".\"3\""
+ " from \"test_collections\"")
.returns("1=3000000000"
+ "; 2=30ff87"
+ "; 3=2015-05-03 11:30:54\n");
}
{code}
