I create table as this

```
CREATE TABLE sm.data (
    did int,
    tid int,
    ts timestamp,
    aval text,
    dval decimal,
    PRIMARY KEY (did, tid, ts)
) WITH CLUSTERING ORDER BY (tid ASC, ts DESC);

```

Before I did all select query with ts DESC so it was good. Now I also need select query with ts ASC in some cases. How do I accomplish that? Thank you
