While you have a valid point that most of the SAP HANA projects are coupled with varied SAP landscape but there does exists a lot of projects which involve only native SAP HANA development.It entirely depends on your interests and knowledge base but sound understanding of the core concepts around data ware housing needs to be clear, if you are planning to build anything utilizing the base concepts.Presently, as per my understanding, clients prefer ABAP on HANA as they have one or other existing ABAP solutions. So, any enhancement using ABAP seems more sensible and appropriate.So I will suggest you ... Read More
This cannot be overridden or suppressed by a pseudo code of pragma. If you run your query with extended syntax check, you will find the message as well that this cannot be suppressed. The extended check can be done by going to PROGRAM => Check => Extended Syntax Check
I don’t think that there exists a way where you can pass dynamic values to the CDS.In order for DCL to do its assigned activity you need to declare and define the authority object. Let’s say you cannot do this. Then you can get all the results and then filter the results at Gateway layer using ABAP.
While writing the name of the constants it is suggested to write all the letters in upper case. If constant contains more than one word they should be separated by underscore (_). Example Live Demo public class ConstantsTest { public static final int MIN_VALUE = 22; public static final int MAX_VALUE = 222; public static void main(String args[]) { System.out.println("Value of the constant MIN_VALUE: "+MIN_VALUE); System.out.println("Value of the constant MAX_VALUE: "+MAX_VALUE); } } Output Value of the constant MIN_VALUE: 22 Value of the constant MAX_VALUE: 222
method hiding − When super class and the sub class contains same methods including parameters, and if they are static and, when called, the super class method is hidden by the method of the sub class this is known as method hiding. Example Live Demo class Demo{ public static void demoMethod() { System.out.println("method of super class"); } } public class Sample extends Demo{ public static void demoMethod() { System.out.println("method of sub class"); } ...

I faced a similar issue earlier but it was because of a bug in JAVA security package (refer link for more details)http://bugs.java.com/bugdatabase/view_bug.do?bug_id=7044060I just got updated myself to latest OpenJDK7 and it solved my issue. I think you can try the same and check if it helps.
If you don’t want to create a custom table then you can for creating a data model with the help of reuse method. You can then save this newly created data model in staging MDG. Other option that you have is Z-table. You can create a Z-table to persist the data.Hope this helps!
A native method in Java is a method whose implementation is written in other languages such as c and c++.The ‘native’ keyword is used as a method to indicate that it is implemented in another language.
You are correct as XSA supports the custom error pages but classic does not support custom error messages.In case you need to do in any way, then what you can try out is you need to parse all requests through a load balancer or a proxy and then show custom error message. And it is not a easy and maintainable approach.
Yes, this and super are keywords in Java. Where ‘this’ is used as a reference of the current object and, ‘super’ is used as a reference to the superclass object.
