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

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

The following connection properties are required in order to connect to data.

• Server: The host name or IP of the server hosting the EnterpriseDB database.
• Port: The port of the server hosting the EnterpriseDB database.

You can also optionally set the following:

• Database: The default database to connect to when connecting to the EnterpriseDB Server. If this is not set, the user's default database will be used.

Connect Using Standard Authentication

To authenticate using standard authentication, set the following:

• User: The user which will be used to authenticate with the EnterpriseDB server.
• Password: The password which will be used to authenticate with the EnterpriseDB server.

Connect Using SSL Authentication

You can leverage SSL authentication to connect to EnterpriseDB data via a secure session. Configure the following connection properties to connect to data:

• SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
• SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
• SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
• SSLClientCertType: The certificate type of the client store.
• SSLServerCert: The certificate to be accepted from the server.

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 EnterpriseDB 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 EnterpriseDB 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 CDataEnterpriseDBODBC 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="EnterpriseDBQuery" dataSource="CDataEnterpriseDBODBC"> 
    SELECT * FROM Orders 
    </cfquery> 
    

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

    
    <cftable 
    query = "EnterpriseDBQuery" 
    border = "1" 
    colHeaders 
    colSpacing = "2" 
    headerLines = "2" 
    HTMLTable 
    maxRows = "500" 
    startRow = "1"> 
   
    <cfcol header="<b>ShipName</b>" align="Left" width=2 text="ShipName"/> 
   
    <cfcol header="<b>ShipCity</b>" align="Left" width=15 text="ShipCity"/> 
   
    ...
   
    </cftable> 
    

   Full code, including the HTML portion is available below:

    
    <html> 
    <head><title>CData Software | EnterpriseDB Orders Table Demo </title></head> 
    <body> 
    <cfoutput>#ucase("EnterpriseDB Orders Table Demo")#</cfoutput> 
    <cfquery name="EnterpriseDBQuery" dataSource="CDataEnterpriseDBODBC"> 
   
    SELECT * FROM Orders 
   
    </cfquery> 
    <cftable 
    query = "EnterpriseDBQuery" 
    border = "1" 
    colHeaders 
    colSpacing = "2" 
    headerLines = "2" 
    HTMLTable 
    maxRows = "500" 
    startRow = "1"> 
    <cfcol header="<b>ShipName</b>" align="Left" width=2 text="ShipName"/> 
   
    <cfcol header="<b>ShipCity</b>" align="Left" width=15 text="ShipCity"/> 
   
    ...
   
    </cftable> 
    </body> 
   
    </html> 
    

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