Validate SAP Netweaver Gateway Data with QuerySurge

QuerySurge is a smart data testing solution that automates data validation and testing. When paired with the CData JDBC Driver for SAP Netweaver Gateway, QuerySurge can work with live SAP Netweaver Gateway data. This article walks through connecting to SAP Netweaver Gateway data from QuerySurge.

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

Connecting to SAP Netweaver Gateway Data in QuerySurge

To connect to live SAP Netweaver Gateway data from QuerySurge, you need to deploy the JDBC Driver JAR file to your QuerySurge Agent(s) and add a new connection from the QuerySurge Admin view.

Deploy the JDBC Driver

1. Download the CData JDBC Driver for SAP Netweaver Gateway installer, unzip the package, and run the JAR file to install the driver.
2. Once the driver is installed, stop the Agent Service.
3. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for SAP Netweaver Gateway\lib\) to your Agent(s) (QuerySurge_install_dir\agent\jdbc).
4. Restart the Agent Service.

For more information on deploying JDBC drivers for QuerySurge, refer to the QuerySurge Knowledge Base.

Configure a New Connection to SAP Netweaver Gateway

1. Log into QuerySurge and navigate to the Admin view.
2. Click Configuration -> Connections in the Administration Tree.
3. Click Add to create a new connection.
4. In the QuerySurge Connection Wizard, click Next.
5. Name the connection (e.g. CData JDBC Connection to SAP Netweaver Gateway).
6. Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
7. Set the Driver Class to cdata.jdbc.sapgateway.SAPGatewayDriver and click Next.

8. Set the Connection URL using the necessary connection properties to authenticate with SAP Netweaver Gateway. Your Connection URL will look something like the following:

   jdbc:sapgateway:User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/;InitiateOAuth=GETANDREFRESH

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.sapgateway.jar

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

   SAP Gateway allows both basic and OAuth 2.0 authentication. You can use basic authentication to connect to your own account, or you can use OAuth to enable other users to retrieve data from your service with their accounts. In addition to authenticating, set the following connection properties to access SAP Gateway tables.

   • Url: Set this to the URL of your environment, or to the full URL of the service. For example, the full URL might appear as: https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/. In this example, the environment URL would just be: https://sapes5.sapdevcenter.com.
   • Namespace: Set the appropriate Service Namespace. In the example above, IWBEP is the namespace. It is optional if the full URL to the service is specified.
   • Service: Set this to the service you want to retrieve data from. In the example above, the service is GWSAMPLE_BASIC. It is not required if the full URL is specified.

   Authenticate via Basic Authentication

   In basic authentication, you use your login credentials to connect. Set the following properties:

   • User: This is the username you use to log in to SAP Gateway.
   • Password: This is the password you use to log in to SAP Gateway.

   Authenticate via OAuth Authentication

   You can connect to SAP Gateway using the embedded OAuth connectivity (without setting any additional authentication connection properties). When you connect, the OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

9. Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM SalesOrderLineItems LIMIT 1) and click Next.
10. Click Test Connection to ensure the connection is configured properly and click Save to add the connection.

Once the connection is added, you can write SQL queries against your SAP Netweaver Gateway data in QuerySurge.

Compare SAP Netweaver Gateway Data Queries with a QueryPair

With the connection configured, you can follow the steps below to compare querying SAP Netweaver Gateway data with a QueryPair.

1. Select "Design Library" from the Design Menu
2. Click QueryPairs under QuerySurge Design
3. Click "Create New QueryPair"
4. Name the QueryPair and click Save
5. In either the Source or Target panes, select the connection created above (select the same connection to query SAP Netweaver Gateway twice or another connection to perform a comparison)
6. Write queries in the Editor for each pane, e.g. SELECT * FROM SalesOrderLineItems
7. Click the "Design-Time Run" tab to execute the queries
8. When the query execution is finished, click "View Query Results" to see the SAP Netweaver Gateway data returned by the query
