> In the case of a table with static columns, if only the static columns have
> been set for some partitions, a multi-partitions query with an {{ORDER BY}}
> can cause a {{NPE}}.
> The following unit test can be used to reproduce the problem:
> {code}
> @Test
> public void testOrderByForInClauseWithNullValue() throws Throwable
> {
> createTable("CREATE TABLE %s (a int, b int, c int, s int static, d
> int, PRIMARY KEY (a, b, c))");
> execute("INSERT INTO %s (a, b, c, d) VALUES (1, 1, 1, 1)");
> execute("INSERT INTO %s (a, b, c, d) VALUES (1, 1, 2, 1)");
> execute("INSERT INTO %s (a, b, c, d) VALUES (2, 2, 1, 1)");
> execute("INSERT INTO %s (a, b, c, d) VALUES (2, 2, 2, 1)");
> execute("UPDATE %s SET s = 1 WHERE a = 1");
> execute("UPDATE %s SET s = 2 WHERE a = 2");
> execute("UPDATE %s SET s = 3 WHERE a = 3");
> assertRows(execute("SELECT a, b, c, d, s FROM %s WHERE a IN (1, 2, 3)
> ORDER BY b DESC"),
> row(2, 2, 2, 1, 2),
> row(2, 2, 1, 1, 2),
> row(1, 1, 2, 1, 1),
> row(1, 1, 1, 1, 1),
> row(3, null, null, null, 3));
> }
> {code}
