             Summary: TUMBLE/HOP/SESSION_START/END do not resolve time field correctly
                 Key: CALCITE-1761
                 URL: https://issues.apache.org/jira/browse/CALCITE-1761
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: Timo Walther
            Assignee: Julian Hyde


It seems there is a bug in the resolution logic of SqlToRelConverter.

The problem is as follows:

Input: {{MyTable(INTEGER a, VARCHAR b, BIGINT c, TIMESTAMP proctime, TIMESTAMP rowtime)}}

SQL: {{SELECT COUNT(*), TUMBLE_START(rowtime, INTERVAL '15' MINUTE), TUMBLE_END(rowtime, INTERVAL '15' MINUTE) FROM MyTable GROUP BY TUMBLE(rowtime, INTERVAL '15' MINUTE)}}

Exception:

{code}
java.lang.RuntimeException: while converting TUMBLE_START(`MyTable`.`rowtime`, INTERVAL '15' MINUTE)

Additionally, tests were added to
SqlToRelConverterTest.xml but not to SqlToRelConverterTest.java. We've
been running without tests.
