# Spanner

UI Bakery allows you to easily connect to a Spanner database with no need for additional layers like APIs or third-party services.

## Configuration

### Prerequisites

To establish a connection between UI Bakery and Spanner, you will first need to [create a private key](https://cloud.google.com/docs/authentication/getting-started).

### Connecting the data source

Once you've obtained the key you can proceed to connecting the data source.

1. On the **Data sources** page, click **Connect**, and select *Spanner* in the Data sources list.
2. Specify the private key you've obtained previously in the **Service Account Credentials** field.
3. Next, provide all other required credentials.
4. Click **Test connection** to check whether the data source can be connected, and then click **Connect Datasource** to complete the setup.

UI Bakery will extract the database structure and store column types. This data will be used to suggest the proper[ table columns and form field types](/concepts/components/work-with-components/field-types-and-types-recognition.md).

## Usage

Once you have established a connection between UI Bakery and Spanner, you can access its data - load it and send it back. Below are the *supported action steps*:

* [Load Table](/reference/working-with-actions/load-table-action.md)
* [Load Row](/reference/working-with-actions/load-row-action.md)
* [Create Row](/reference/working-with-actions/create-row-action.md)
* [Bulk Create Rows](/reference/working-with-actions/bulk-create-rows-action.md)
* [Update Row](/reference/working-with-actions/update-row-action.md)
* [Delete Row](/reference/working-with-actions/delete-row-action.md)
* [Bulk Delete Rows](/reference/working-with-actions/bulk-delete-rows-action.md)
* [SQL Query](/reference/working-with-actions/sql-query.md)

You can run the action and make sure the data is loaded in the **Result** tab.
