Request-Processing API Example
The following example shows how to use the request-processing API to display the message “Hello World” in a
browser.
$.response.contentType = "text/plain";
$.response.setBody( "Hello, World !");
Database API Example
The following example shows how to use the database API to prepare and execute an SQL statement. The
response to the SQL query is then prepared and displayed in a Web browser.
var conn = $.db.getConnection();
var pstmt = conn.prepareStatement( "select * from DUMMY" );
var rs = pstmt.executeQuery();
$.response.contentType = "text/plain";
if (!rs.next()) {
$.response.setBody( "Failed to retreive data" );
$.response.status = $.net.http.INTERNAL_SERVER_ERROR;
} else {
$.response.setBody("Response: " + rs.getString(1));
}
rs.close();
pstmt.close();
conn.close();

SAP HANA XS JavaScript Reference
9.5 The SQL Connection Configuration File
In SAP HANA Extended Application Services (SAP HANA XS), you use the SQL-connection configuration file to
enable the execution of SQL statements from inside your server-side JavaScript application with credentials that
are different to the credentials of the requesting user.
In cases where it is necessary to execute SQL statements from inside your JavaScript application with credentials
that are different to the credentials of the requesting user, SAP HANA XS enables you to define the configuration
for individual SQL connections. Each connection configuration has a unique name, for example, Registration or
AdminConn, which is generated from the name of the corresponding connection-configuration file
(Registration.xssqlcc or AdminConn.xssqlcc) on activation in the repository. The administrator can
assign specific, individual database users to this configuration, and you can use the configuration name to
reference the unique SQL connection configuration from inside your JavaScript application code.
If you want to create an SQL connection configuration, you must create the configuration as a flat file and save the
file with the suffix .xssqlcc, for example, MYSQLconnection.xssqlcc. The new configuration file must be
located in the same package as the application that references it. You can activate repository files at any point in
time.
