Discover how a bimodal integration strategy can address the major data management challenges facing your organization today.
Get the Report →Query SAP Data as a MySQL Database in Node.js
Execute MySQL queries against SAP data from Node.js.
You can use the SQL Gateway from the ODBC Driver for SAP to query SAP data through a MySQL interface. Follow the procedure below to start the MySQL remoting service of the SQL Gateway and start querying using Node.js.
About SAP Data Integration
CData provides the easiest way to access and integrate live data from SAP. Customers use CData connectivity to:
- Access every edition of SAP, including SAP R/3, SAP NetWeaver, SAP ERP / ECC 6.0, and SAP S/4 HANA on premises data that is exposed by the RFC.
- Perform actions like sending IDoc or IDoc XML files to the server and creating schemas for functions or queries through SQL stored procedures.
-
Connect optimally depending on where a customer's SAP instance is hosted.
- Customers using SAP S/4HANA cloud public edition will use SAP NetWeaver Gateway connectivity
- Customers using SAP S/4HANA private edition will use either SAP ERP or SAP NetWeaver Gateway connectivity.
While most users leverage our tools to replicate SAP data to databases or data warehouses, many also integrate live SAP data with analytics tools such as Tableau, Power BI, and Excel.
Getting Started
Connect to SAP Data
If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.
You can connect to SAP systems using either librfc32.dll, librfc32u.dll, NetWeaver, or Web Services (SOAP). Set the ConnectionType connection property to CLASSIC (librfc32.dll), CLASSIC_UNICODE (librfc32u.dll), NETWEAVER, or SOAP.
If you are using the SOAP interface, set the Client, RFCUrl, SystemNumber, User, and Password properties, under the Authentication section.
Otherwise, set Host, User, Password, Client, and SystemNumber.
Note: We do not distribute the librfc32.dll or other SAP assemblies. You must find them from your SAP installation and install them on your machine.
For more information, see this guide on obtaining the connection properties needed to connect to any SAP system.
Configure the SQL Gateway
See the SQL Gateway Overview to set up connectivity to SAP data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.
Query SAP from Node.js
The following example shows how to define a connection and execute queries to SAP with the mysql module. You will need the following information:
- Host name or address, and port: The machine and port where the MySQL remoting service is listening for MySQL connections.
- Username and password: The username and password of a user you authorized on the Users tab of the SQL Gateway.
- Database name: The DSN you configured for the MySQL remoting service.
Connect to SAP data and start executing queries with the code below:
var mysql = require('mysql'); var connection = mysql.createConnection({ host : 'localhost', database : 'CData SAPERP Sys', port : '3306', user : 'mysql_user', password : 'test' }); connection.connect(); connection.query('SELECT * FROM MARA', function(err, rows, fields) { if (err) throw err; console.log(rows); }); connection.end();
