Query SAS Data Sets Data as a MySQL Database in Node.js

You can use the SQL Gateway from the ODBC Driver for SAS Data Sets to query SAS Data Sets 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.

Connect to SAS Data Sets 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.

Set the following connection properties to connect to your SAS DataSet files:

Connecting to Local Files

• Set the Connection Type to "Local." Local files support SELECT, INSERT, and DELETE commands.
• Set the URI to a folder containing SAS files, e.g. C:\PATH\TO\FOLDER\.

Connecting to Cloud-Hosted SAS DataSet Files

While the driver is capable of pulling data from SAS DataSet files hosted on a variety of cloud data stores, INSERT, UPDATE, and DELETE are not supported outside of local files in this driver.

Set the Connection Type to the service hosting your SAS DataSet files. A unique prefix at the beginning of the URI connection property is used to identify the cloud data store and the remainder of the path is a relative path to the desired folder (one table per file) or single file (a single table). For more information, refer to the Getting Started section of the Help documentation.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to SAS Data Sets 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 SAS Data Sets from Node.js

The following example shows how to define a connection and execute queries to SAS Data Sets 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 SAS Data Sets data and start executing queries with the code below:

var mysql = require('mysql');
var connection = mysql.createConnection({
 host : 'localhost',
 database : 'CData SASDataSets Sys',
 port	 : '3306',
 user : 'mysql_user',
 password : 'test'
});
connection.connect();
connection.query('SELECT * FROM restaurants', function(err, rows, fields) {
 if (err) throw err;
 console.log(rows);
});

connection.end();
