Paul Rogers updated DRILL-5246:
-------------------------------
Description:
The following is valid in DRILL:
{code}
SELECT * FROM (VALUES ( TRUE, FALSE ))
SELECT * FROM (VALUES ( TRUE ), (FALSE))
{code}
But, the following is not:
{code}
SELECT * FROM (VALUES ( TRUE, NULL, FALSE ))
SELECT * FROM (VALUES ( TRUE ), (FALSE), (NULL))
{code}
Internally, a bare "null" may be an issue since Drill does not have a null
type. So, the first example might be a problem (a column for which the only
value is Null, but we don't know a null of which type.) But, the second example
should be fine: we know that the type is boolean.
While Drill's error reporting in the web UI is not clear, it seems that I'm
getting a syntax error when using Null:
{code}
org.apache.drill.common.exceptions.UserRemoteException: VALIDATION ERROR:
>From line 1, column 43 to line 1, column 46: Illegal use of 'NULL' SQL Query
>null
{code}
