# SQL Server

## Configuration

### Prerequisites

If your database is hosted behind a Firewall, you need to add our [IP addresses](/concepts/data-sources.md#whitelisting-ip-addresses) to the Firewall whitelist.

### Connecting the data source

1. On the **Data sources** page, click **Connect**, and select *SQL Server* in the Data sources list.
2. Specify all the required credentials.
3. 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).

If you need to be able to override the default data source database with a custom value in an action, you can enable the **Allow override database name in action** setting in the *Data source connection* window.\
Once enabled you will be able to specify a custom database when configuring an action. In case a database is not specified, the default data source database will be used.

## Usage

Once you've established the connection between UI Bakery and SQL Server, you can start interacting with its data. Below is a list of *supported action steps*:

* [SQL Query](/reference/working-with-actions/sql-query.md)
* [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)
