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

             Summary: need better error - cast interval day to int or bigint
                 Key: DRILL-5029
                 URL: https://issues.apache.org/jira/browse/DRILL-5029
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow
    Affects Versions: 1.8.0
            Reporter: Khurram Faraaz
            Priority: Minor


We need a better error message, today Drill returns an AssertionError

{noformat}
0: jdbc:drill:schema=dfs.tmp> values(cast('P162M24D' as INTERVAL DAY));
+---------+
| EXPR$0  |
+---------+
| P24D    |
+---------+
1 row selected (0.419 seconds)
{noformat}

A better error would be
ERROR:  cannot cast type interval to int

{noformat}
0: jdbc:drill:schema=dfs.tmp> values(cast(cast('P162M24D' as INTERVAL DAY) as INT));
Error: SYSTEM ERROR: AssertionError: Internal error: Conversion to relational algebra failed to preserve datatypes:
