Import Real-Time BigQuery Data via ODBC in ColdFusion to Build Applications

Use CData ODBC drivers to import and use BigQuery data in ColdFusion.

Adobe ColdFusion is a web and mobile application development platform. It uses its own scripting language, ColdFusion Markup Language (CFML), to create data-driven websites as well as generate remote services, such as REST. When ColdFusion is paired with the CData ODBC Driver for Google BigQuery, you can link your ColdFusion web and mobile applications to operational BigQuery data. This allows for your applications to be more robust and complete. This article details how to use the ODBC driver to create a table populated with BigQuery data from within a ColdFusion markup file.

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

To follow along with this tutorial, you need to install the CData ODBC Driver for Google BigQuery and Adobe ColdFusion.

Configuring the Connection

If you have not already, first specify connection properties in an ODBC DSN (Data Source Name). This is the last step of the driver installation process. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

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.

Adding a Data Source and Creating a Table

After creating a DSN, follow the steps below to add a new data source, test our connection to it, create a ColdFusion markup file, and, finally, import BigQuery Data and display it in a table in ColdFusion:

From the ColdFusion administrator interface, choose Data & Services. 👁 Selecting Data & Services
Here, click "Add New Data Source". The data source name can be any name, provided it conforms to the ColdFusion variable naming conventions. For our ODBC driver, choose "ODBC Socket", then click the "Add" button. 👁 Adding Data Source Name
From the ODBC DSN Dropdown menu select CData BigQuery Sys. Under the Advanced Settings section, leave the Connection String blank. Note that any properties specified in this input field will override the ones specified in the DSN Configuration. 👁 Populating driver properties
Now, test the connection by pressing the check mark to the left of the CDataBigQueryODBC data source you just created. When the data source reports an "OK" status, it is ready for use. 👁 Testing the connection

Next, create a new ColdFusion Markup file (.cfm) and place it in the wwwroot directory ("C:\ColdFusion2021\cfusion\wwwroot") for ColdFusion.

The following code queries the data source:

 
 <cfquery name="BigQueryQuery" dataSource="CDataBigQueryODBC"> 
 SELECT * FROM Orders 
 </cfquery>

And a CFTable can be used to quickly output the table in HTML:

 
 <cftable 
 query = "BigQueryQuery" 
 border = "1" 
 colHeaders 
 colSpacing = "2" 
 headerLines = "2" 
 HTMLTable 
 maxRows = "500" 
 startRow = "1"> 

 <cfcol header="<b>OrderName</b>" align="Left" width=2 text="OrderName"/> 

 <cfcol header="<b>Freight</b>" align="Left" width=15 text="Freight"/> 

 ...

 </cftable>

Full code, including the HTML portion is available below:

 
 <html> 
 <head><title>CData Software | BigQuery Orders Table Demo </title></head> 
 <body> 
 <cfoutput>#ucase("BigQuery Orders Table Demo")#</cfoutput> 
 <cfquery name="BigQueryQuery" dataSource="CDataBigQueryODBC"> 

 SELECT * FROM Orders 

 </cfquery> 
 <cftable 
 query = "BigQueryQuery" 
 border = "1" 
 colHeaders 
 colSpacing = "2" 
 headerLines = "2" 
 HTMLTable 
 maxRows = "500" 
 startRow = "1"> 
 <cfcol header="<b>OrderName</b>" align="Left" width=2 text="OrderName"/> 

 <cfcol header="<b>Freight</b>" align="Left" width=15 text="Freight"/> 

 ...

 </cftable> 
 </body> 

 </html>

Finally, run the code in a browser. It produces a table populated with BigQuery data! 👁 Running the code

As a note, the CData ODBC Drivers also support parameterized queries using the cfqueryparam element. For example:

SELECT * FROM Account WHERE name =
