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

Use CData ODBC drivers to import and use Phoenix 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 Phoenix, you can link your ColdFusion web and mobile applications to operational Phoenix 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 Phoenix data from within a ColdFusion markup file.

To follow along with this tutorial, you need to install the CData ODBC Driver for Phoenix 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.

Connect to Apache Phoenix via the Phoenix Query Server. Set the Server and Port (if different from the default port) properties to connect to Apache Phoenix. The Server property will typically be the host name or IP address of the server hosting Apache Phoenix.

Authenticating to Apache Phoenix

By default, no authentication will be used (plain). If authentication is configured for your server, set AuthScheme to NEGOTIATE and set the User and Password properties (if necessary) to authenticate through Kerberos.

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 Phoenix 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 Phoenix 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 CDataPhoenixODBC 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="PhoenixQuery" dataSource="CDataPhoenixODBC"> 
 SELECT * FROM MyTable 
 </cfquery>

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

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

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

 <cfcol header="<b>Column1</b>" align="Left" width=15 text="Column1"/> 

 ...

 </cftable>

Full code, including the HTML portion is available below:

 
 <html> 
 <head><title>CData Software | Phoenix MyTable Table Demo </title></head> 
 <body> 
 <cfoutput>#ucase("Phoenix MyTable Table Demo")#</cfoutput> 
 <cfquery name="PhoenixQuery" dataSource="CDataPhoenixODBC"> 

 SELECT * FROM MyTable 

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

 <cfcol header="<b>Column1</b>" align="Left" width=15 text="Column1"/> 

 ...

 </cftable> 
 </body> 

 </html>

Finally, run the code in a browser. It produces a table populated with Phoenix 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 =

Phoenix ODBC Driver

The Phoenix ODBC Driver is a powerful tool that allows you to connect with HBase through Apache Phoenix, directly from any applications that support ODBC connectivity.

Access Phoenix like you would a relational database - read, write, and update through a standard ODBC Driver interface.
