You are making a basic mistake over here. A VORA virtual table does not support the traditional INSERT or UPDATE or DELETE statements. If you are planning to make any modification to data from VORA itself, then you need to use the APPEND command to add data or files to the table. But since you are trying from SAP HANA even this will not work for you. For your requirement, you need to have a HDFS file then use it for appending to the virtual table.
You can contents of a blob into a byte array using the getBytes() method.Exampleimport java.awt.Image; import java.awt.image.BufferedImage; import java.sql.Blob; import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.Statement; import java.util.Arrays; public class BlobToByteArray { public static void main(String[] args) throws Exception { Image image = new BufferedImage(300, 400, BufferedImage.TYPE_INT_RGB); String JDBC_DRIVER = "com.mysql.jdbc.Driver"; String DB_URL = "jdbc:mysql://localhost/mydb"; String USER = "root"; String PASS = "password"; ...

As you had already mentioned that extended services are natively integrated with HANA, so it’s going to be easier to use against HANA but as it is native to HANA only it can’t be used elsewhere. It will be faster when you compare it against ODBC because the extra step will be avoided here as it is native to HANA. Also, as it is integrated other factors like latency and other would be out of question which can be considerable factors with ODBC.Extended Services follow the MVC architecture so you need not worry about the implementation style as it will ...

The Y-namespace is meant to be used for centrally developed solutions or also known as head office while the Z-namespace is used for local developed solutions or also known as branch office. But at the end of day, it all depends on the developer how he uses it.
There are lots of free and proprietary tools to do the same. You can use Memory Analyzer project done by SAP. It lets you find memory leaks against in-memory objects via simple SQL statements. Also, you can use JHAT (Java Heap Analysis tool) command line tool to examine the memory. It lets you examine heap memory via histogram and can be of good help. Also, you can go for HeapWalker from Netbeans or Visual VM. Also, Eclipse has Eclipse memory analyzer which is a freeware and can handle good size with dump and provides a fair deal of memory analysis.Read More
Yes, the PBO-PAI triggers commit so your requirement will fail. You need to make changes to your current implementation to avoid the auto-commit.
A class in Java is a user-defined datatype, a blueprint, a classification, that describes the behavior/state that the object of its type support. Example public class Dog { String breed; int age; String color; void barking() { } void hungry() { } void sleeping() { } } A class can contain any of the following variable types. Local variables − Variables defined inside methods, constructors or blocks are called local ... Read More
One solution to add an array to set is to use the addAll() method of the Collections class. This method accepts a collection and an element and, it adds the given element to the specified Collection. Example Live Demo import java.util.Collections; import java.util.HashSet; import java.util.Set; public class ArrayToSet { public static void main(String args[]) { Integer[] myArray = {23, 93, 56, 92, 39}; Set set = new HashSet(); Collections.addAll(set, myArray); System.out.println(set); } } Output [23, 39, 56, 92, 93]

JScript and JavaScript are different names for the same language. They have different names to avoid trademark issues.
SAP uses IDoc known as an intermediate document to exchange data between logical systems. If your system involves non-SAP systems as well, then IDoc can be used as a standard interface for data exchange between SAP and non-SAP systems.IDoc is a container for information exchange. IDoc is made by message type and method of Objects when information is to be exchanged. The message type is the configuration in which the information for a particular business process is transmitted electronically. An IDoc consists of several data segments, headers and status records. Also, it can be extended by extending IDoc types to add ... Read More
