Connect to ServiceNow Data and Transfer Data in Talend

This article shows how you can easily integrate the CData JDBC driver for ServiceNow into your workflow in Talend. This article uses the CData JDBC Driver for ServiceNow to transfer ServiceNow data in a job flow in Talend.

Connect to ServiceNow in Talend as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to ServiceNow:

1. Add a new database connection to ServiceNow data: To add a new connection, expand the Metadata node, right-click the Db Connections node, and then click Create Connection.
2. In the resulting wizard, enter a name for the connection.

3. On the next page, select Generic JDBC from the DB Type menu and enter the JDBC URL.

   ServiceNow uses the OAuth 2.0 authentication standard. To authenticate using OAuth, you will need to register an OAuth app with ServiceNow to obtain the OAuthClientId and OAuthClientSecret connection properties. In addition to the OAuth values, you will need to specify the Instance, Username, and Password connection properties.

   See the "Getting Started" chapter in the help documentation for a guide on connecting to ServiceNow.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.servicenow.jar

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

   A typical JDBC URL is below:

   jdbc:servicenow:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;Username=MyUsername;Password=MyPassword;Instance=MyInstance;InitiateOAuth=GETANDREFRESH
4. Enter the path to the cdata.jdbc.servicenow.jar file, located in the lib subfolder of the installation directory.
5. Right-click the connection and then click Retrieve Schema.
6. Click Next with the default options to select the tables you want to import.
7. Finish the wizard with the default options.

Output the Incident Table to a Flat File

You can follow the procedure below to transfer the incident table to a flat file output component:

1. In the Table Schemas node, drag the tables to the workspace.
2. In the dialog that is displayed, select the tJDBCInput component.
3. Next, drag a tFileOutputDelimited component from the Business Intelligence tab of the Palette into the workspace.
4. Right-click the incident tJDBCInput component and drag a vector to the output file.

Run the project to transfer the data.
