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

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

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

Connecting to Azure Synapse

In addition to providing authentication (see below), set the following properties to connect to a Azure Synapse database:

  • Server: The server running Azure. You can find this by logging into the Azure portal and navigating to Azure Synapse Analytics -> Select your database -> Overview -> Server name.
  • Database: The name of the database, as seen in the Azure portal on the Azure Synapse Analytics page.

Authenticating to Azure Synapse

Connect to Azure Synapse using the following properties:

  • User: The username provided for authentication with Azure.
  • Password: The password associated with the authenticating user.

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 Azure Synapse Data and display it in a table in ColdFusion:

  1. From the ColdFusion administrator interface, choose Data & Services. 👁 Selecting Data & Services
  2. 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
  3. From the ODBC DSN Dropdown menu select CData Azure Synapse 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
  4. Now, test the connection by pressing the check mark to the left of the CDataAzure SynapseODBC data source you just created. When the data source reports an "OK" status, it is ready for use. 👁 Testing the connection
  5. 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="Azure SynapseQuery" dataSource="CDataAzure SynapseODBC"> 
 SELECT * FROM Products 
 </cfquery>
    And a CFTable can be used to quickly output the table in HTML: 
     
 <cftable 
 query = "Azure SynapseQuery" 
 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>ProductName</b>" align="Left" width=15 text="ProductName"/> 

 ...

 </cftable>
    Full code, including the HTML portion is available below: 
     
 <html> 
 <head><title>CData Software | Azure Synapse Products Table Demo </title></head> 
 <body> 
 <cfoutput>#ucase("Azure Synapse Products Table Demo")#</cfoutput> 
 <cfquery name="Azure SynapseQuery" dataSource="CDataAzure SynapseODBC"> 

 SELECT * FROM Products 

 </cfquery> 
 <cftable 
 query = "Azure SynapseQuery" 
 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>ProductName</b>" align="Left" width=15 text="ProductName"/> 

 ...

 </cftable> 
 </body> 

 </html>
  6. Finally, run the code in a browser. It produces a table populated with Azure Synapse 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 =
