Redshift order by DESC is not working

Question

hello,
i've a very simple query of the pattern SELECT timestamp_column FROM a_table WHERE columnID = 'column_value' ORDER BY timestamp_column DESC
the result set does not come back in descending order
i've rewritten this in many ways.
any ideas?
thanks!

Answer

I tested below and I see that ordering is properly applied highest to lowest.  Can you check if timestamp_column is defined as timestamp not string?

```
create table test_ts_order
(timestamp_column  timestamp);

insert into test_ts_order 
select getdate()
--wait few seconds
insert into test_ts_order 
select getdate()
--wait few seconds
insert into test_ts_order 
select getdate()
```

```
select * from test_ts_order order by timestamp_column desc;

```

* 2022-11-11 21:46:47
* 2022-11-11 21:46:22

```
select version()
```
