----------------------------------
Summary: SqlToRelConverter: SELECT 1 IS [NOT] DISTINCT FROM NULL fails with AssertionError
Key: CALCITE-4258
URL: https://issues.apache.org/jira/browse/CALCITE-4258
Project: Calcite
Issue Type: Bug
Components: core
Reporter: Ruben Q L
Problem can be reproduced with the following tests (in core\src\test\resources\sql\misc.iq):
{code}
#
SELECT 1 IS DISTINCT FROM NULL;
+--------+
| EXPR$0 |
+--------+
| true |
+--------+
(1 row)
!ok
#
SELECT 1 IS NOT DISTINCT FROM NULL;
+--------+
| EXPR$0 |
+--------+
| false |

(1 row)
!ok
{code}
These tests fail with:
{code}
> java.lang.AssertionError: Conversion to relational algebra failed to preserve datatypes:
> validated type:
> RecordType(BOOLEAN NOT NULL EXPR$0) NOT NULL
> converted type:
> RecordType(BOOLEAN EXPR$0) NOT NULL
> rel:
> LogicalProject(EXPR$0=[null:BOOLEAN])
> LogicalValues(tuples=[[{ 0 }]])
