# MD_DELETE_DIVE
> Delete a Dive and its version history.
Deletes a [Dive](/key-tasks/ai-and-motherduck/dives), including all of its versions. Deletion is permanent — there is no undo.

Deleting a Dive that does not exist (or was already deleted) returns a `Could not find Dive` error.

## Syntax

```sql
SELECT * FROM MD_DELETE_DIVE(id := '<dive_id>');
```

## Parameters

| Parameter | Type | Required | Description |
|---|---|---|---|
| `id` | `UUID` | Yes | Identifier of the Dive to delete. |

## Return columns

| Column | Type | Description |
|---|---|---|
| `success` | `BOOLEAN` | `true` when the Dive was deleted. |

## Examples

```sql
SELECT success
FROM MD_DELETE_DIVE(id := '80000000-0000-0000-0000-000000000001');
```

After deletion, the Dive is no longer reachable through [`MD_LIST_DIVES`](../md-list-dives), [`MD_GET_DIVE`](../md-get-dive), or any other Dive function.
