Import Real-Time Perigon Data via ODBC in ColdFusion to Build Applications
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 API Driver for ODBC, you can link your ColdFusion web and mobile applications to operational Perigon 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 Perigon data from within a ColdFusion markup file.
To follow along with this tutorial, you need to install the CData API Driver for ODBC 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.
Using API Key Authentication
To use the Perigon API, you need to obtain an API key from your Perigon account. Navigate to the Perigon dashboard and generate an API key from your account settings.
After setting the following connection properties, you are ready to connect:
- AuthScheme: Set this to APIKey.
- APIKey: Set this to your Perigon API key.
Example connection string:
Profile=C:\profiles\Perigon.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key"
Available Tables
The Perigon profile provides access to the following tables:
- Articles - News articles retrieved from the Perigon news intelligence API
- Headlines - Story clusters grouping related headline articles
- Sources - News sources tracked by the Perigon news intelligence API
- Journalists - Journalist profiles tracked by the Perigon news intelligence API
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 Perigon Data and display it in a table in ColdFusion:
-
From the ColdFusion administrator interface, choose 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.
-
From the ODBC DSN Dropdown menu select CData Perigon 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.
-
Now, test the connection by pressing the check mark to the left of the CDataPerigonODBC data source you just created.
When the data source reports an "OK" status, it is ready for use.
-
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="PerigonQuery" dataSource="CDataPerigonODBC"> SELECT * FROM Articles </cfquery>And a CFTable can be used to quickly output the table in HTML:<cftable query = "PerigonQuery" border = "1" colHeaders colSpacing = "2" headerLines = "2" HTMLTable maxRows = "500" startRow = "1"> <cfcol header="<b></b>" align="Left" width=2 text=""/> <cfcol header="<b></b>" align="Left" width=15 text=""/> ... </cftable>Full code, including the HTML portion is available below:<html> <head><title>CData Software | Perigon Articles Table Demo </title></head> <body> <cfoutput>#ucase("Perigon Articles Table Demo")#</cfoutput> <cfquery name="PerigonQuery" dataSource="CDataPerigonODBC"> SELECT * FROM Articles </cfquery> <cftable query = "PerigonQuery" border = "1" colHeaders colSpacing = "2" headerLines = "2" HTMLTable maxRows = "500" startRow = "1"> <cfcol header="<b></b>" align="Left" width=2 text=""/> <cfcol header="<b></b>" align="Left" width=15 text=""/> ... </cftable> </body> </html> -
Finally, run the code in a browser. It produces a table populated with Perigon data!
As a note, the CData ODBC Drivers also support parameterized queries using the cfqueryparam element. For example:
SELECT * FROM Account WHERE name =
