# Generate a Trino connection string for external tools

## Objective

A **Trino consumer** generates a ready-to-use Trino connection string in a few clicks. Previously, connecting an external tool to your project over Trino meant creating a service account, generating API keys, and assembling the connection string by hand. A Trino consumer does all of that for you.

You'll find them in the Connectors service, under the **Consumers** tab, in the **Trino consumers** section of **Registered consumers**.

:::info
Unlike the PowerBI and OpenLineage consumers (which you connect once), you can create as many Trino consumers as you need. Each with its own name, permission level, and credentials.
:::

## Create a Trino consumer

1. In the **Trino consumers** section, click **+ New Trino consumer**.

   <img className="thumbnail" alt="Create a Trino consumer — Trino consumer new" src="/images/public-cloud/data-platform/product/connectors/consumers/trino/picts/trino-consumer-new.png" loading="lazy" />

2. Give it a **name**, an optional **description**, and optional **tags**.

3. Set the **permission**: the access level this Trino consumer has on your data:

   | Permission       | Access                            |
   | :--------------- | :-------------------------------- |
   | **READ**         | Query and retrieve data only.     |
   | **READ & WRITE** | Query, retrieve, and modify data. |

   <img className="thumbnail" alt="Create a Trino consumer — Trino consumer permission" src="/images/public-cloud/data-platform/product/connectors/consumers/trino/picts/trino-consumer-permission.png" loading="lazy" />

4. Click **Create**.

5. Your **Trino connection string** appears.

:::warning
Copy the connection string now and store it somewhere safe (for example, a password manager). You can't view it again after you close this window, if you lose it, you'll have to create a new Trino consumer.
:::

## Manage the linked service account

Each Trino consumer has a dedicated [service account](https://docs.ovhcloud.com/es/guides/public-cloud/data-platform/iam-service-accounts.md) in your project's Identity Access Manager. After you create the consumer, click **Go to service account settings** to view and manage it.

The project **admin also receives an email** containing the Trino connector credentials.

## Use the connection string

The connection string is ready to paste into any external Trino-compatible client or BI tool. It embeds the credentials and follows this shape:

```text
trino://<api-key>:<secret-key>@<project>-query.eu.dataplatform.ovh.net:443/<catalog>
```

Plug it into your tool of choice, for example:

[Deploy Apache Superset](https://docs.ovhcloud.com/es/guides/public-cloud/data-platform/tutorials-install-apache-superset.md)

[Connect Metabase to Data Platform via Trino](https://docs.ovhcloud.com/es/guides/public-cloud/data-platform/tutorials-metabase-trino.md)

:::warning
Any user connecting through a Trino consumer accesses data according to the consumer's permission and the project's [IAM roles and groups](https://docs.ovhcloud.com/es/guides/public-cloud/data-platform/landing-page-iam-users.md). Treat the connection string like a password.
:::

## Query a different catalog

By default, the connection string targets your project's **default dataset** catalog (the trailing `/<catalog>` segment, e.g. `db_<project>_default_dataset`).

To query a **different catalog** in the project, replace that trailing `/<catalog>` segment of the connection string. To list the available catalog names, run the following in the [Lakehouse Manager Explorer](https://docs.ovhcloud.com/es/guides/public-cloud/data-platform/lakehouse-manager-explorer.md):

```sql
SHOW CATALOGS
```

For the full breakdown of the connection string and how to build one by hand, see [Integrating Trino with External Tools](https://docs.ovhcloud.com/es/guides/public-cloud/data-platform/tutorials-trino-external-tools.md).

:::info
Writing data through Trino sometimes requires an explicit `CAST`. See [Trino data types and casts](https://docs.ovhcloud.com/es/guides/public-cloud/data-platform/tutorials-trino-types-and-casts.md) for the mapping between Lakehouse types and Trino types, and for troubleshooting `TYPE_MISMATCH` errors.
