# ClickHouse

## Create a connection to ClickHouse

The following instructions show how to create a basic connection to ClickHouse.

{% hint style="success" %}
Your connection is persistent, so you won't need to re-create it for every job. The connection is also shared with other users in your organization. 
{% endhint %}

**Here's the code to create a connection your ClickHouse database:**

```sql
// Syntax
CREATE CLICKHOUSE CONNECTION <connection name>
    CONNECTION_STRING = 'http://<host_name>:8123/<db_name>'
    USER_NAME = 'your username'
    PASSWORD = 'your password';

// Example
CREATE CLICKHOUSE CONNECTION my_clickhouse_connection
    CONNECTION_STRING = 'http://upsolver_demo:8123/sales_orders'
    USER_NAME = 'dbuser1'
    PASSWORD = 'mypassword';
```

This code creates a connection named **my\_clickhouse\_connection** that uses the **sales\_orders** database.

## 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/quickstarts-1/connectors/connectors/clickhouse.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.
