In MySQL, a user-defined variable defined by one client cannot be seen or used by another client because user-defined variables are connection-specific. It means that all variables for a given client connection are automatically freed when that client exits
In MySQL, it is not possible that a client can hold user variable permanently. It is because all the variables for a given client connection are automatically freed when that client exits.
LM structure in SAP HANA system landscape is used to manage installation details of all the components under HANA. LM structure information helps to manage software updates and patches. The information with LM structure is used by Software Update Manager SUM to install the software updates and new releases in HANA environment.
remove(int index) − Removes the element at position index from the invoking list and returns the deleted element. The resulting list is compacted. That is, the indexes of subsequent elements are decremented by one. removeRange(int fromIndex, int toIndex) − Removes all of the elements whose index is between fromIndex, inclusive and toIndex, exclusive. removeAll(Collection c) − Removes from this list all of its elements that are contained in the specified collection (optional operation).
This is used to update versions of HANA Studio to newer versions. Studio Repository maintains the code to perform updates for HANA Studio.All the objects that you develop are maintained in Packages which are maintained under SAP HANA Repository. These packages are arranged in the form of hierarchy to make them easy to understand and logical.
As we know that with the help of QUOTE() function we can put the values of a column in single quotes. By using QUOTE() function with UPDATE clause we can update the table having quoted values. We need to give column name as the parameter of QUOTE() function. Following example will update the table ‘examination_btech’ after putting the values of column ‘Course’ in single quotes. Example mysql> UPDATE examination_btech SET Course = QUOTE(Course); Query OK, 10 rows affected (0.05 sec) mysql> Select * from examination_btech; +--------+----------+----------+ | RollNo | Name | Course ...

You can compare two array lists using the equals() method of the ArrayList class, this method accepts a list object as a parameter, compares it with the current object, in case of the match it returns true and if not it returns false.Example Live Demoimport java.util.ArrayList; public class ComparingList { public static void main(String[] args) { ArrayList list1 = new ArrayList(); list1.add("JavaFx"); list1.add("Java"); list1.add("WebGL"); list1.add("OpenCV"); ArrayList list2 = new ArrayList(); list2.add("JavaFx"); list2.add("Java"); list2.add("WebGL"); ...

By default, all .NET objects are reference types and their equality and hash code is determined by their memory address. Additionally, assigning a variable to an existing object just makes it point to that address in memory, so there is no costly copying occurring. It appears that this is true for python objects as well to certain extent.Properties of Python objects: All python objects havea unique identity (an integer, returned by id(x)); a type (returned by type(x))You cannot change the identity; You cannot change the type.Some objects allow you to change their content (without changing the identity or the type, that is).Some ...

Java lang package provides Integer class which has methods to convert integer to String and vice versa. You can convert a String to an integer using the parseInt() method and Integer to String using the toString() method.Example Live Demopublic class Sample { public static void main(String args[]) { String str = "1212"; int num = Integer.parseInt(str); System.out.println(num); String st = Integer.toString(num); System.out.println(); } }Output1212 1212
By default it creates a Row store table. The horizontal lines in front of table name represents row based storage table in database. HANA database also supports column store tables but you need to add a keyword “Column” in create table query.Below snapshot confirms that by default a row based table is created.
