In continuation of previous example (see Website with HANA XSJS backend), this development
example illustrates simplicity of sap.m and $.hdb functionality for web applications (see sap.m demo kit reference and $.hdb documentation).

With this steadily improving and powerful framework provided by SAP, HANA cloud platform is ideal for any web application. Leverage below code/walkthrough, in addition to exemplary aforementioned documentation from SAP, to create your own website including analytics, scripts for forms, applications, etc. all using HANA backend.

From SAP HANA Web-based Development Workbench, navigate to Catalog to Create HCP table CONTACTS under your schema with “contacts table creation.sql”

create column table <SCHEMA>.contacts (
System 		nvarchar(3)  not null,
Client 		nvarchar(3)  not null,
guid       	nvarchar(9) not null,
full_name    	nvarchar(80)  not null,
organization   	nvarchar(80) not null,
email           nvarchar(80)  not null,
phone           nvarchar(80)  not null,
notes           nvarchar(1024) not null,
PRIMARY KEY
(
System,
Client,
guid
)
); 

From SAP HANA Web-based Development Workbench, navigate to Editor to Create contact.html, form.xsjs, style.css under HCP HANA project (right-click
Content/project folder and source files attached respectively)

var Name = $.request.parameters.get("NAME");
var NameObj = JSON.parse(Name);
var Org = $.request.parameters.get("ORG");
var OrgObj = JSON.parse(Org);
var Email = $.request.parameters.get("EMAIL");
var EmailObj = JSON.parse(Email);
var Phone = $.request.parameters.get("PHONE");
var PhoneObj = JSON.parse(Phone);
var Notes = $.request.parameters.get("NOTES");
var NotesObj = JSON.parse(Notes);
var conn = $.hdb.getConnection();
var sysuuid = conn.executeQuery( 'SELECT SYSUUID FROM DUMMY;' );
var guid  = JSON.stringify(sysuuid);
var replace2 = "{\"0\":{\"SYSUUID\":[";  //JSON.parse to guidObj.0.SYSUUID or metadata.SYSUUID not working
var replace3 = "]}}";
var replace4 =  /,/gi;
guid = guid.replace(replace2, '');
guid = guid.replace(replace3, '');
guid = guid.replace(replace4, '');
var trun = 32;
var guid32 = guid.substring(0,trun);
var results = conn.executeUpdate('insert into ACTUALS.CONTACTS values (\'HDB\',\'100\',?,?,?,?,?,?)   ', guid32 , NameObj , OrgObj, EmailObj, PhoneObj, NotesObj );
conn.commit();
$.response.setBody(JSON.stringify(results));

    Todd,

    thanks for sharing this example of how to use the web work bench to maintain some records with the HANA DB on HCP. For your new UI development, try to use the Web IDE.

    I think it is a good and simple example you shared here. I think it would be helpful to specify what version of HANA / HCP you are using. What version of sapui5?  Also, I would recommend to start looking into XML views as that has been the direction (instead of JS views) both will work fine, but for the direction going fwd would be to use XML views.

    As far as your XSJS code goes, yes it seems like it would work… I would suggest you look into moving your SQL code into a stored proc… it will help with preventing SQL injection, and other possible risks, etc… It is good that you used $.hdb instead of the old $.db API…

     

    thanks again for sharing.. hope this was a good learning opportunity! good luck on your ongoing dev!

    Hi

     

    Thanks for a good article, but I get an error :  http://linux-ucyy:8090/Affecto/form.xsjs 500 (Internal Server Error). Any idea what the cause can be. Im running Hana express 2.0.

     

    It may be some problem with my 2.0 version and the script..
