Import Real-Time Neo4J Data via ODBC in ColdFusion to Build Applications

Use CData ODBC drivers to import and use Neo4J 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 Neo4J, you can link your ColdFusion web and mobile applications to operational Neo4J 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 Neo4J data from within a ColdFusion markup file.

To follow along with this tutorial, you need to install the CData ODBC Driver for Neo4J 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 to Neo4j, set the following connection properties:

Server: The server hosting the Neo4j instance.
Port: The port on which the Neo4j service is running. The provider connects to port 7474 by default.
User: The username of the user using the Neo4j instance.
Password: The password of the user using the Neo4j instance.

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 Neo4J Data and display it in a table in ColdFusion:

From the ColdFusion administrator interface, choose Data & Services. 👁 Selecting Data & Services
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
From the ODBC DSN Dropdown menu select CData Neo4J 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
Now, test the connection by pressing the check mark to the left of the CDataNeo4JODBC data source you just created. When the data source reports an "OK" status, it is ready for use. 👁 Testing the connection

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="Neo4JQuery" dataSource="CDataNeo4JODBC"> 
 SELECT * FROM ProductCategory 
 </cfquery>

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

 
 <cftable 
 query = "Neo4JQuery" 
 border = "1" 
 colHeaders 
 colSpacing = "2" 
 headerLines = "2" 
 HTMLTable 
 maxRows = "500" 
 startRow = "1"> 

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

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

 ...

 </cftable>

Full code, including the HTML portion is available below:

 
 <html> 
 <head><title>CData Software | Neo4J ProductCategory Table Demo </title></head> 
 <body> 
 <cfoutput>#ucase("Neo4J ProductCategory Table Demo")#</cfoutput> 
 <cfquery name="Neo4JQuery" dataSource="CDataNeo4JODBC"> 

 SELECT * FROM ProductCategory 

 </cfquery> 
 <cftable 
 query = "Neo4JQuery" 
 border = "1" 
 colHeaders 
 colSpacing = "2" 
 headerLines = "2" 
 HTMLTable 
 maxRows = "500" 
 startRow = "1"> 
 <cfcol header="<b>CategoryId</b>" align="Left" width=2 text="CategoryId"/> 

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

 ...

 </cftable> 
 </body> 

 </html>

Finally, run the code in a browser. It produces a table populated with Neo4J 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 =
