Connect to BigQuery Data in RazorSQL

Connect to BigQuery from wizards and query BigQuery data from the GUI in the RazorSQL database management tool.

The CData JDBC Driver for BigQuery enables standards-based access from third-party tools, from wizards in IDEs to data management and analysis tools. This article shows how to connect to BigQuery using wizards in RazorSQL.

About BigQuery Data Integration

CData simplifies access and integration of live Google BigQuery data. Our customers leverage CData connectivity to:

Simplify access to BigQuery with broad out-of-the-box support for authentication schemes, including OAuth, OAuth JWT, and GCP Instance.
Enhance data workflows with Bi-directional data access between BigQuery and other applications.
Perform key BigQuery actions like starting, retrieving, and canceling jobs; deleting tables; or insert job loads through SQL stored procedures.

Most CData customers are using Google BigQuery as their data warehouse and so use CData solutions to migrate business data from separate sources into BigQuery for comprehensive analytics. Other customers use our connectivity to analyze and report on their Google BigQuery data, with many customers using both solutions.

Getting Started

Create a JDBC Data Source for BigQuery Data

Open the RazorSQL application and, in the Connections menu, select Add Connection Profile -> Other -> JDBC.
In the Connection Wizard that appears, set the following properties:
- Driver Location: Set this property to the path to the lib subfolder in the installation directory.
- Driver Class: Set the driver class to cdata.jdbc.googlebigquery.GoogleBigQueryDriver.
- Username: Enter the username. (This property can also be set in the JDBC URL.)
- Password: Enter the password. (This property can also be set in the JDBC URL.)
- JDBC URL: Enter connection parameters. The JDBC URL begins with jdbc:googlebigquery: and is followed by a semicolon-separated list of 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, register an application to obtain the OAuth JWT values.
  
  In addition to the OAuth values, specify the DatasetId and ProjectId. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.
  
  Built-in Connection String Designer
  
  For assistance in constructing the JDBC URL, use the connection string designer built into the BigQuery JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
```
java -jar cdata.jdbc.googlebigquery.jar
```
  Fill in the connection properties and copy the connection string to the clipboard.

  A typical JDBC URL is the following:
```
jdbc:googlebigquery:DataSetId=MyDataSetId;ProjectId=MyProjectId;InitiateOAuth=GETANDREFRESH;
```

Query BigQuery Data and Select Tables

After establishing a connection, the wizard will close and the connection will be available in the connections panel. You can then query the tables.
