In the following example, the rows in the result show actions taken by Amazon Redshift. 

```
select table_id, type, status, eventtime, sequence, previous_state
from SVL_AUTO_WORKER_ACTION;
```

```
 table_id |  type   |                        status                        |         eventtime          | sequence | previous_state
