# Update table with custom Time to Live (TTL)
<a name="TTL-how-to-enable-custom-alter"></a>

To enable Time to Live custom settings for a table so that TTL values can be applied to individual rows and columns without setting a TTL default value for the entire table, you can use the following commands.

**Note**  
After `ttl` is enabled, you can't disable it for the table.

------
#### [ Cassandra Query Language (CQL) ]

**Enable custom TTL settings for a table using CQL**
+ 

  ```
  ALTER TABLE my_table WITH CUSTOM_PROPERTIES={'ttl':{'status': 'enabled'}};
  ```

------
#### [ CLI ]

**Enable custom TTL settings for a table using the AWS CLI**

1. You can use the following command to update the custom TTL setting of a table.

   ```
   aws keyspaces update-table --keyspace-name 'myKeyspace' --table-name 'myTable' --ttl 'status=ENABLED'
   ```

1. To confirm that TTL is now enabled for the table, you can use the following statement.

   ```
   aws keyspaces get-table --keyspace-name 'myKeyspace' --table-name 'myTable'
   ```

   The output of the statement should look like in the following example.

   ```
