---------------------------------------

             Summary: Type mismatch during flattening
                 Key: CALCITE-2290
                 URL: https://issues.apache.org/jira/browse/CALCITE-2290
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: Laurent Goujon
            Assignee: Julian Hyde


The following query causes Calcite not being able to perform SQL to Rel 
conversion:
{code:sql}
select (res1 = 'qwe') res2 from (select (case when (false) then null else 'qwe' 
end) res1 from (values(1)))
{code}
 
While adding the query to {{SqlToRelConverTest}}, the test generates the 
following output:
{noformat}
java.lang.AssertionError: 
type mismatch:
ref:
CHAR(3) CHARACTER SET "ISO-8859-1" COLLATE "ISO-8859-1$en_US$primary"
input:
CHAR(3) CHARACTER SET "ISO-8859-1" COLLATE "ISO-8859-1$en_US$primary" NOT NULL
        at 
org.apache.calcite.test.SqlToRelConverterTest.testCaseFlatten(SqlToRelConverterTest.java:2786)
{noformat}
