> Phoenix doesn't handle NULLs consistently with other SQL dialects, and it
> doesn't handle them consistently internally either.
> In PHOENIX-2422, [~jamestaylor] mentioned that Phoenix's intended behavior is
> for empty string and NULL to be equivalent. That's inconsistent with other
> SQL dialects (in which NULL is never equal to anything, including itself),
> but if that's our documented behavior, then that's fine unless PHOENIX-2422
> to change it is ever worked.
> But consider the following queries:
> {code:java}
> SELECT COUNT(*) FROM SYSTEM.CATALOG WHERE TENANT_ID = '';
> -- Returns 0 rows
> SELECT COUNT(*) FROM SYSTEM.CATALOG WHERE TENANT_ID IS NULL;
> -- Returns some number of rows. Call it N
> SELECT COUNT(*) FROM SYSTEM.CATALOG WHERE TENANT_ID IN ('');
> -- Returns 0 rows
> SELECT COUNT(*) FROM SYSTEM.CATALOG WHERE TENANT_ID IN ('', 'FOO');
> -- Returns N rows. Note that FOO does not exist, and is just a nonsense string
> SELECT COUNT(*) FROM SYSTEM.CATALOG WHERE TENANT_ID = '' OR TENANT_ID = 'FOO'
> --Returns 0 rows, but slowly
> {code}
