How to Import BigQuery Data into SQL Server using SSIS

Using SQL Server as a backup for critical business data provides an essential safety net against loss. Backing up data to SQL Server enables business users to more easily connect that data with features like reporting, analytics, and more.

This example demonstrates how to use the CData SSIS Tasks for BigQuery inside of a SQL Server SSIS workflow to transfer BigQuery data into a Microsoft SQL Server database.

Getting Started

---

Add the Components

To get started, add a new BigQuery source and SQL Server ADO.NET destination to a new data flow task.

Create a New Connection Manager

Follow the steps below to save BigQuery connection properties in a connection manager.

1. In the Connection Manager window, right-click and then click New Connection. The Add SSIS Connection Manager dialog is displayed.
2. In the Connection Manager type menu, select GoogleBigQuery. The CData BigQuery Connection Manager is displayed.
3. Configure connection properties.

   Google uses the OAuth authentication standard. To access Google APIs on behalf of individual users, you can use the embedded credentials or you can register your own OAuth app.

   OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

   In addition to the OAuth values, you will need to specify the DatasetId and ProjectId. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

Configure the BigQuery Source

Follow the steps below to specify the query to be used to extract BigQuery data.

1. Double-click the BigQuery source to open the source component editor.
2. In the Connection Manager menu, select the connection manager previously created.
3. Specify the query to use for the data extraction. For example: SELECT OrderName, Freight FROM Orders
4. Close the BigQuery Source control and connect it to the ADO.NET Destination.

Configure the SQL Server Destination

Follow the steps below to specify the SQL server table to load the BigQuery data into.

1. Open the ADO.NET Destination and add a New Connection. Enter your server and database information here.
2. In the Data access mode menu, select "table or view".
3. In the Table Or View menu, select the table or view to populate.
4. Configure any properties you wish to on the Mappings screen.

Run the Project

You can now run the project. After the SSIS Task has finished executing, your database will be populated with BigQuery data.
