Import Real-Time IBM Cloud Data Engine Data 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 JDBC Driver for IBM Cloud Data Engine, you can link your ColdFusion web and mobile applications to operational IBM Cloud Data Engine data. This allows for your applications to be more robust and complete. This article details how to use the JDBC driver to create a table populated with IBM Cloud Data Engine data from within a ColdFusion markup file.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live IBM Cloud Data Engine data. When you issue complex SQL queries to IBM Cloud Data Engine, the driver pushes supported SQL operations, like filters and aggregations, directly to IBM Cloud Data Engine and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze IBM Cloud Data Engine data using native data types.

Configuring the Connection to IBM Cloud Data Engine

You will need a JDBC connection string to establish a connection between Coldfusion and IBM Cloud Data Engine.

IBM Cloud Data Engine uses the OAuth and HMAC authentication standards. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the IBM Cloud Data Engine JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

Adding a Data Source and Creating a Table

After configuring the connection, follow the steps below to add the CData JDBC Driver to ColdFusion's lib directory, add a new data source, test the connection, create a ColdFusion markup file, and, finally, make a real-time connection with IBM Cloud Data Engine data and display it in a table written in the ColdFusion Markup Language, or CFML:

1. Copy the JDBC Driver for IBM Cloud Data Engine and lic file from "C:\Program Files\CData[product_name]\lib" to "C:\ColdFusion2021\cfusion\wwwroot\WEB-INF\lib". cdata.jdbc.ibmclouddataengine.jar cdata.jdbc.ibmclouddataengine.lic

   Note: If you do not copy the .lic file with the jar, you will see a licensing error that indicates you do not have a valid license installed. This is true for both the trial and full versions.

2. From the ColdFusion administrator interface, choose Data & Services.
3. Here, we can "Add New Data Source". The data source name can be any name, provided it conforms to the ColdFusion variable naming conventions. For our JDBC driver, choose "other", then click the "Add" button.
4. Next, populate the driver properties.
   • JDBC URL will need to be in the format: jdbc:ibmclouddataengine:|connectionString|.
   • A typical connection string looks like this:

     jdbc:ibmclouddataengine:Api Key=MyAPIKey;Instance CRN=myInstanceCRN;Region=myRegion;Schema=mySchema;OAuth Client Id=myOAuthClientId;OAuth Client Secret=myOAuthClientSecret;InitiateOAuth=GETANDREFRESH

   • The Driver Class is: cdata.jdbc.ibmclouddataengine.IBMCloudDataEngineDriver
   • The Driver Name is arbitrary and simply used to recognize the data source in the ColdFusion administration console.
5. Now, test the connection by clicking the check mark to the left of the CDataIBM Cloud Data EngineJDBC data source you just created. When the data source reports an "OK" status, it is ready for use.
6. 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="IBM Cloud Data EngineQuery" dataSource="CDataIBM Cloud Data EngineJDBC"> 
             SELECT * FROM Jobs 
           </cfquery> 
       

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

               
             <cftable  
             query = "IBM Cloud Data EngineQuery" 
             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>Status</b>" align="Left" width=15 text="Status"/> 
   
             ...
   
           </cftable> 
       

   Full code, including the HTML portion is available below:

               
           <html> 
           <head><title>CData Software | IBM Cloud Data Engine Jobs Table Demo </title></head> 
           <body> 
           <cfoutput>#ucase("IBM Cloud Data Engine Jobs Table Demo")#</cfoutput> 
           <cfquery name="IBM Cloud Data EngineQuery" dataSource="CDataIBM Cloud Data EngineJDBC"> 
   
             SELECT * FROM Jobs 
   
           </cfquery> 
           <cftable  
             query = "IBM Cloud Data EngineQuery" 
             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>Status</b>" align="Left" width=15 text="Status"/> 
   
             ...
   
           </cftable> 
           </body> 
   
           </html>  
       

7. Finally, run the code locally in a browser at the default port of 8500. It produces a table populated with IBM Cloud Data Engine data!

As a note, the CData JDBC Drivers also support parameterized queries using the cfqueryparam element. For example: SELECT * FROM Account WHERE name =
