Query BigQuery Data in DataGrip

DataGrip is a database IDE that allows SQL developers to query, create, and manage databases. When paired with the CData JDBC Driver for Google BigQuery, DataGrip can work with live BigQuery data. This article shows how to establish a connection to BigQuery data in DataGrip and use the table editor to load BigQuery data.

Getting Started

Create a New Driver Definition for BigQuery

The steps below describe how to create a new Data Source in DataGrip for BigQuery.

1. In DataGrip, click File -> New > Project and name the project 👁 Creating a new DataGrip project.
   
2. In the Database Explorer, click the plus icon () and select Driver. 👁 Adding a new Driver.
   
3. In the Driver tab:
   • Set Name to a user-friendly name (e.g. "CData BigQuery Driver")
   • Set Driver Files to the appropriate JAR file. To add the file, click the plus (), select "Add Files," navigate to the "lib" folder in the driver's installation directory and select the JAR file (e.g. cdata.jdbc.googlebigquery.jar).
   • Set Class to cdata.jdbc.googlebigquery.GoogleBigQuery.jar
4. Click "Apply" then "OK" to save the Connection 👁 A configured Driver (Salesforce is shown).
   

Configure a Connection to BigQuery

1. Once the connection is saved, click the plus (), then "Data Source" then "CData BigQuery Driver" to create a new BigQuery Data Source.
2. In the new window, configure the connection to BigQuery with a JDBC URL.

   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.

   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.

   👁 Using the built-in connection string designer to generate a JDBC URL (Salesforce is shown.)
   
3. Set URL to the connection string, e.g.,

   jdbc:googlebigquery:DataSetId=MyDataSetId;ProjectId=MyProjectId;InitiateOAuth=GETANDREFRESH;

4. Click "Apply" and "OK" to save the connection string 👁 A configured Data Source (Salesforce is shown).
   

At this point, you will see the data source in the Data Explorer.

Execute SQL Queries Against BigQuery

To browse through the BigQuery entities (available as tables) accessible through the JDBC Driver, expand the Data Source.

To execute queries, right click on any table and select "New" -> "Query Console."

In the Console, write the SQL query you wish to execute. For example:

SELECT OrderName, Freight FROM Orders
