# 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.

After executing an action, you might also want to transform or map your data and display it in a component. Check out the following pages for more information👇

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.uibakery.io/reference/data-sources/spanner.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
