Calling XSJS file in SAPUI5 for writng data on HANA

I'm trying to create a service to write data from a SAPUI5 frontend to HANA tables. As far as I checked, I believe this is not possible via OData Services. So I've found another way, sing an XSJS file with a SQL INSERT statement.

Now, my problem is using this in UI5. As with OData, I would use something like oModel.create but now I think this doesn't work like that.

Those anyone has a clue?

Thanks!

Eva

UPDATE: After using the first answer, I tried to create an entry in a HANA Table, but I'm getting a 500 error. Here's the code of the xsjs file:

var data = '', conn = $.db.getConnection(), pstmt;  

        if($.request.body){
            data = $.request.parameters.get("firstName");   
        }

        var conn = $.db.getConnection();
        var pstmt = conn.prepareStatement( 'INSERT INTO "Z003HB1N"."T_TEST" (FIRSTNAME) VALUES(?)' );

        pstmt.setString(1,data);

        pstmt.execute();
        pstmt.close();

        conn.commit();
        conn.close();

        doResponse(200,'');

        $.response.contentType = 'text/plain';
        $.response.setBody('Upload ok');
        $.response.status = 200;

Any clue what might be wrong?

You can simply use .ajax calls to call your new oData service on HANA and use parameters to hand over the desired values to your .xsjs service.

Example: 

var query = "firstName=Sherlock&lastName=Holmes"
jQuery.ajax({
    url : "url/to/your/Service.xsjs?" + query,
    success : function(response) {
        // will be called once the xsjs file sends a response
        console.log(response);
    },
    error : function(e) {
        // will be called in case of any errors:
        console.log(e);
    }
});

On HANA you can access the provided parameters in your service like this:

var firstName = $.request.parameters.get("firstName");
var lastName = $.request.parameters.get("lastName");
