Elasticsearch Icon Elasticsearch ODBC Driver

The Elasticsearch ODBC Driver is a powerful tool that allows you to connect with live Elasticsearch document databases, directly from any applications that support ODBC connectivity.

Access Elasticsearch like you would a database - read, write, and update through a standard ODBC Driver interface.

Import Real-Time Elasticsearch Data in ColdFusion to Build Applications


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

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

Set the Server and Port connection properties to connect. To authenticate, set the User and Password properties, PKI (public key infrastructure) properties, or both. To use PKI, set the SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword properties.

The data provider uses X-Pack Security for TLS/SSL and authentication. To connect over TLS/SSL, prefix the Server value with 'https://'. Note: TLS/SSL and client authentication must be enabled on X-Pack to use PKI.

Once the data provider is connected, X-Pack will then perform user authentication and grant role permissions based on the realms you have configured.

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 Elasticsearch Elasticsearch 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 Elasticsearch 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 CDataElasticsearchODBC 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="ElasticsearchQuery" dataSource="CDataElasticsearchODBC"> 
          SELECT * FROM Orders 
        </cfquery>
    And a CFTable can be used to quickly output the table in HTML: 
                
          <cftable  
          query = "ElasticsearchQuery" 
          border = "1" 
          colHeaders 
          colSpacing = "2" 
          headerLines = "2" 
          HTMLTable 
          maxRows = "500" 
          startRow = "1"> 

          <cfcol header="<b>OrderName</b>" align="Left" width=2 text="OrderName"/> 

          <cfcol header="<b>Freight</b>" align="Left" width=15 text="Freight"/> 

          ...

        </cftable>
    Full code, including the HTML portion is available below: 
                
        <html> 
        <head><title>CData Software | Elasticsearch Orders Table Demo </title></head> 
        <body> 
        <cfoutput>#ucase("Elasticsearch Orders Table Demo")#</cfoutput> 
        <cfquery name="ElasticsearchQuery" dataSource="CDataElasticsearchODBC"> 

          SELECT * FROM Orders 

        </cfquery> 
        <cftable  
          query = "ElasticsearchQuery" 
          border = "1" 
          colHeaders 
          colSpacing = "2" 
          headerLines = "2" 
          HTMLTable 
          maxRows = "500" 
          startRow = "1"> 
          <cfcol header="<b>OrderName</b>" align="Left" width=2 text="OrderName"/> 

          <cfcol header="<b>Freight</b>" align="Left" width=15 text="Freight"/> 

          ...

        </cftable> 
        </body> 

        </html>
  6. Finally, run the code in a browser. It produces a table populated with Elasticsearch data!

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