# Step 3 - \[ESX] Changes

{% hint style="info" %}
Download [esx\_context](https://github.com/esx-framework/esx_core/tree/main/%5Bcore%5D/esx_context)
{% endhint %}

{% hint style="danger" %}
For older ESX versions, you need to change some things in esx\_context. If you have no idea what to do, join my Discord and open a support ticket. I'll help you.
{% endhint %}

Next, you need to check if your "users" table has an column named "last\_seen".\
If not, insert this SQL.

{% code lineNumbers="true" %}

```sql
ALTER TABLE users
ADD `last_seen` timestamp NULL DEFAULT current_timestamp() ON UPDATE current_timestamp();
```

{% endcode %}
