Import Real-Time SQL Analysis Services 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 ODBC Driver for SQL Analysis Services, you can link your ColdFusion web and mobile applications to operational SQL Analysis Services 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 SQL Analysis Services data from within a ColdFusion markup file.

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

To connect, provide authentication and set the Url property to a valid SQL Server Analysis Services endpoint. You can connect to SQL Server Analysis Services instances hosted over HTTP with XMLA access. See the Microsoft documentation to configure HTTP access to SQL Server Analysis Services.

To secure connections and authenticate, set the corresponding connection properties, below. The data provider supports the major authentication schemes, including HTTP and Windows, as well as SSL/TLS.

• HTTP Authentication

  Set AuthScheme to "Basic" or "Digest" and set User and Password. Specify other authentication values in CustomHeaders.

• Windows (NTLM)

  Set the Windows User and Password and set AuthScheme to "NTLM".

• Kerberos and Kerberos Delegation

  To authenticate with Kerberos, set AuthScheme to NEGOTIATE. To use Kerberos delegation, set AuthScheme to KERBEROSDELEGATION. If needed, provide the User, Password, and KerberosSPN. By default, the data provider attempts to communicate with the SPN at the specified Url.

• SSL/TLS:

  By default, the data provider attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

You can then access any cube as a relational table: When you connect the data provider retrieves SSAS metadata and dynamically updates the table schemas. Instead of retrieving metadata every connection, you can set the CacheLocation property to automatically cache to a simple file-based store.

See the Getting Started section of the CData documentation, under Retrieving Analysis Services Data, to execute SQL-92 queries to the cubes.

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 SQL Analysis Services SQL Analysis Services data and display it in a table in ColdFusion:

1. From the ColdFusion administrator interface, choose 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.
3. From the ODBC DSN Dropdown menu select CData SQL Analysis Services 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.
4. Now, test the connection by pressing the check mark to the left of the CDataSQL Analysis ServicesODBC data source you just created. When the data source reports an "OK" status, it is ready for use.
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="SQL Analysis ServicesQuery" dataSource="CDataSQL Analysis ServicesODBC"> 
             SELECT * FROM Adventure_Works 
           </cfquery> 
       

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

               
             <cftable  
             query = "SQL Analysis ServicesQuery" 
             border = "1" 
             colHeaders 
             colSpacing = "2" 
             headerLines = "2" 
             HTMLTable 
             maxRows = "500" 
             startRow = "1"> 
   
             <cfcol header="<b>Fiscal_Year</b>" align="Left" width=2 text="Fiscal_Year"/> 
   
             <cfcol header="<b>Sales_Amount</b>" align="Left" width=15 text="Sales_Amount"/> 
   
             ...
   
           </cftable> 
       

   Full code, including the HTML portion is available below:

               
           <html> 
           <head><title>CData Software | SQL Analysis Services Adventure_Works Table Demo </title></head> 
           <body> 
           <cfoutput>#ucase("SQL Analysis Services Adventure_Works Table Demo")#</cfoutput> 
           <cfquery name="SQL Analysis ServicesQuery" dataSource="CDataSQL Analysis ServicesODBC"> 
   
             SELECT * FROM Adventure_Works 
   
           </cfquery> 
           <cftable  
             query = "SQL Analysis ServicesQuery" 
             border = "1" 
             colHeaders 
             colSpacing = "2" 
             headerLines = "2" 
             HTMLTable 
             maxRows = "500" 
             startRow = "1"> 
             <cfcol header="<b>Fiscal_Year</b>" align="Left" width=2 text="Fiscal_Year"/> 
   
             <cfcol header="<b>Sales_Amount</b>" align="Left" width=15 text="Sales_Amount"/> 
   
             ...
   
           </cftable> 
           </body> 
   
           </html>  
       

6. Finally, run the code in a browser. It produces a table populated with SQL Analysis Services data!

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