Subject [jira] [Created] (CALCITE-1620) CAST('<string>' AS BINARY) is supported by Hive, but not by Calcite
Date Mon, 06 Feb 2017 21:35:41 GMT
Remus Rusanu created CALCITE-1620:
-------------------------------------

             Summary: CAST('<string>' AS BINARY) is supported by Hive, but not by Calcite
                 Key: CALCITE-1620
                 URL: https://issues.apache.org/jira/browse/CALCITE-1620
             Project: Calcite
          Issue Type: Bug
            Reporter: Remus Rusanu
            Assignee: Julian Hyde


Hive supports CAST('1' as BINARY). Result is 0x31 (can be tested with {noformat}SELECT HEX(CAST('1'
as BINARY));{noformat}. If I'm not mistaken, the CAST result is the UTF-8 encoding of the
input string.
CALCITE 1.11 throws AssertionException during compilation for such an expression:
