# DROP CONNECTION

This command deletes the specified connection in Upsolver.

{% hint style="warning" %}
If existing tables or jobs are dependent upon the connection, the connection cannot be deleted.
{% endhint %}

If a connection is dropped, it is no longer visible or usable. However, the credentials provided may continue to be used to finish deleting the data of any recently dropped tables that were created using the connection.

## Syntax

Drop a connection using a SQL command:

```sql
DROP CONNECTION [ IF EXISTS ] <connection_identifier>; 
```

#### `IF EXISTS`

(Optional) To prevent the Upsolver query engine from returning an error if the connection does not exist, include `IF EXISTS` in your `DROP` statement; instead, you will see the message **Operation resulted in no change**.

## Example

The following example runs a `DROP` statement with `IF EXISTS` to drop the connection, **my\_test\_conn**. By including `IF EXISTS`, an error is not encountered if the connection does not exist. Otherwise, if the connection exists, it will be dropped from the organization:&#x20;

```sql
DROP CONNECTION IF EXISTS "my_test_conn";
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://upsolver.gitbook.io/content/reference-1/sql-commands/connections/drop-connection.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
