Connect to ZenRows Data in HULFT Integrate

HULFT Integrate is a modern data integration platform that provides a drag-and-drop user interface to create cooperation flows, data conversion, and processing so that complex data connections are easier than ever to execute. When paired with the CData API Driver for JDBC, HULFT Integrate can work with live ZenRows data. This article explains how to connect to ZenRows and move the data into a CSV file.

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

Enable Access to ZenRows

To enable access to ZenRows data from HULFT Integrate projects:

1. Copy the CData JDBC Driver JAR file (and license file if it exists), cdata.jdbc.api.jar (and cdata.jdbc.api.lic), to the jdbc_adapter subfolder for the Integrate Server
2. Restart the HULFT Integrate Server and launch HULFT Integrate Studio

Build a Project with Access to ZenRows Data

Once you copy the JAR files, you can create a project with access to ZenRows data. Start by opening Integrate Studio and creating a new project.

1. Name the project
2. Ensure the "Create script" checkbox is checked
3. Click Next
4. Name the script (e.g.: APItoCSV)

Once you create the project, add components to the script to copy ZenRows data to a CSV file.

Configure an Execute Select SQL Component

Drag an "Execute Select SQL" component from the Tool Palette (Database -> JDBC) into the Script workspace.

1. In the "Required settings" tab for the Destination, click "Add" to create a new connection for ZenRows. Set the following properties:
   • Name: ZenRows Connection Settings
   • Driver class name: cdata.jdbc.api.APIDriver
   • URL: jdbc:api:Profile=C:\profiles\ZenRows.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';
     
     

     Built-in Connection String Designer

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

     
     		java -jar cdata.jdbc.api.jar
     		

     Fill in the connection properties and copy the connection string to the clipboard.

     Start by setting the Profile connection property to the location of the ZenRows Profile on disk (e.g. C:\profiles\ZenRows.apip). Next, set the ProfileSettings connection property to the connection string for ZenRows (see below).

     ZenRows API Profile Settings

     To use the ZenRows API, you need to obtain an API key from your ZenRows account. Navigate to the ZenRows dashboard at app.zenrows.com and copy your API key from the account settings.

     After setting the following connection properties, you are ready to connect:

     • AuthScheme: Set this to APIKey.
     • APIKey: Set this to your ZenRows API key.
     
2. Write your SQL statement. For example:

   SELECT ProductId, ProductName FROM AmazonDiscovery

3. Click "Extraction test" to ensure the connection and query are configured properly
4. Click "Execute SQL statement and set output schema"
5. Click "Finish"

Configure a Write CSV File Component

Drag a "Write CSV File" component from the Tool Palette (File -> CSV) onto the workspace.

1. Set a file to write the query results to (e.g. AmazonDiscovery.csv)
2. Set "Input data" to the "Select SQL" component
3. Add columns for each field selected in the SQL query
4. In the "Write settings" tab, check the checkbox to "Insert column names into first row"
5. Click "Finish"

Map ZenRows Fields to the CSV Columns

Map each column from the "Select" component to the corresponding column for the "CSV" component.

Finish the Script

Drag the "Start" component onto the "Select" component and the "CSV" component onto the "End" component. Build the script and run the script to move ZenRows data into a CSV file.
