integer);
No rows affected (0.86 seconds)
0: jdbc:phoenix:> upsert into tbl values('id1', 'aaa', 2);
1 row affected (0.078 seconds)
0: jdbc:phoenix:> upsert into tbl values('id2', null, 1);
1 row affected (0.008 seconds)
0: jdbc:phoenix:> select sum(case when col1 is not null then col2 else 0 end),
sum(case when col1 is null then col2 else 0 end) from tbl;
+-------------------------------------------------------+-------------------------------------------------------+
| SUM(CASE WHEN COL1 IS NOT NULL THEN COL2 ELSE 0 END) | SUM(CASE WHEN COL1 IS
NOT NULL THEN COL2 ELSE 0 END) |
