You may need to modify the installed driver definition if you change the path to the driver library. For example, below is the entry for the DSN created during the driver install:ĬData GoogleBigQuery Source = CData ODBC Driver for GoogleBigQuery Registering a DSN for iODBC with odbcinst.ini If you wish to authenticate using OAuth, you will need to add an additional connection property to ensure that the OAuth flow can execute properly: Other = CheckPromptMode=FalseĪdditionally, in the ODBC Data Sources section, the DSN must be set to a driver defined in the odbcinst.ini file. Place your connection properties at the beginning of odbc.ini:ĭriver = CData ODBC Driver for GoogleBigQuery In addition to the connection properties required to connect to GoogleBigQuery, the Driver property specifies either a driver definition in the odbcinst.ini file or the path to the driver library. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations. When you configure the DSN, you may also want to set the Max Rows connection property. See the 'Getting Started' chapter of the help documentation for a guide to using OAuth. In addition to the OAuth values, you will need to specify the DatasetId and ProjectId. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain.

To access Google APIs on behalf of individual users, you can use the embedded credentials or you can register your own OAuth app. Google uses the OAuth authentication standard. Modifying iODBC's system-wide settings requires elevated permissions to do so, you can use following to open a text editor from the terminal: You can find the correct odbc.ini in the following paths: System data sources can be accessed by all users. User data sources can only be accessed by the user account whose home folder the odbc.ini is located in. You can define ODBC data sources in sections in the odbc.ini file.

To activate a trial license, omit the key input.Ĭd '/Applications/CData ODBC Driver for GoogleBigQuery/bin' In a terminal run the following commands to license the driver. This makes the driver easy to use with these tools. The CData ODBC Driver for BigQuery is preconfigured for the iODBC driver manager, as are many other products like Microsoft Excel. Installing the CData ODBC Drivers on Mac OS X This article walks through creating a DSN for BigQuery data in iODBC and accessing BigQuery data in Microsoft Excel, all on a machine running Mac OS X. Microsoft Excel features calculations, graphing tools, pivot tables, and a macro programming language that allows users to work with data in many of the ways that suit their needs, whether on a Windows machine or a Macintosh machine.
