Import Real-Time SingleStore Data in ColdFusion to Build Applications



Use the CData JDBC Driver for SingleStore to import and use SingleStore 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 JDBC Driver for SingleStore, you can link your ColdFusion web and mobile applications to operational SingleStore 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 SingleStore data from within a ColdFusion markup file.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live SingleStore data. When you issue complex SQL queries to SingleStore, the driver pushes supported SQL operations, like filters and aggregations, directly to SingleStore 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 SingleStore data using native data types.

Configuring the Connection to SingleStore

You will need a JDBC connection string to establish a connection between Coldfusion and SingleStore.

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

  • Server: The host name or IP of the server hosting the SingleStore database.
  • Port: The port of the server hosting the SingleStore database.
  • Database (Optional): The default database to connect to when connecting to the SingleStore Server. If this is not set, tables from all databases will be returned.

Connect Using Standard Authentication

To authenticate using standard authentication, set the following:

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

Connect Using Integrated Security

As an alternative to providing the standard username and password, you can set IntegratedSecurity to True to authenticate trusted users to the server via Windows Authentication.

Connect Using SSL Authentication

You can leverage SSL authentication to connect to SingleStore 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.

Connect Using SSH Authentication

Using SSH, you can securely login to a remote machine. To access SingleStore data via SSH, configure the following connection properties:

  • SSHClientCert: Set this to the name of the certificate store for the client certificate.
  • SSHClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
  • SSHClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
  • SSHClientCertType: The certificate type of the client store.
  • SSHPassword: The password that you use to authenticate with the SSH server.
  • SSHPort: The port used for SSH operations.
  • SSHServer: The SSH authentication server you are trying to authenticate against.
  • SSHServerFingerPrint: The SSH Server fingerprint used for verification of the host you are connecting to.
  • SSHUser: Set this to the username that you use to authenticate with the SSH server.

Built-in Connection String Designer

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

java -jar cdata.jdbc.singlestore.jar

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 SingleStore data and display it in a table written in the ColdFusion Markup Language, or CFML:

  1. Copy the JDBC Driver for SingleStore and lic file from "C:\Program Files\CData\CData JDBC Driver for SingleStore\lib" to "C:\ColdFusion2021\cfusion\wwwroot\WEB-INF\lib". cdata.jdbc.singlestore.jar cdata.jdbc.singlestore.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:singlestore:|connectionString|.
    • A typical connection string looks like this:

      jdbc:singlestore:User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;

    • The Driver Class is: cdata.jdbc.singlestore.SingleStoreDriver
    • 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 CDataSingleStoreJDBC 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="SingleStoreQuery" dataSource="CDataSingleStoreJDBC"> 
              SELECT * FROM Orders 
            </cfquery> 
        
    And a CFTable can be used to quickly output the table in HTML:
                
              <cftable  
              query = "SingleStoreQuery" 
              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 | SingleStore Orders Table Demo </title></head> 
            <body> 
            <cfoutput>#ucase("SingleStore Orders Table Demo")#</cfoutput> 
            <cfquery name="SingleStoreQuery" dataSource="CDataSingleStoreJDBC"> 
    
              SELECT * FROM Orders 
    
            </cfquery> 
            <cftable  
              query = "SingleStoreQuery" 
              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>  
        
  7. Finally, run the code locally in a browser at the default port of 8500. It produces a table populated with SingleStore data!

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