Tech-Reloded

                                 Hello geeks,  Java 8 or 1.8 come up with lots of enhancements to survive into market. Since, other programming languages are evolving itself beyond object oriented world. Since, java until now strictly follows object oriented approach, that's why a lots of programming methodologies (like function programming etc) are still not supported by java until java 1.7. But in java 8 they started to adopt such programming methodologies too. In this particular blog i am mainly going to talk about the java 8 interface. Since interfaces are there in java from there very first releases, so what new in java 8 interface. Interfaces in java till 1.7 To get a better clear picture, lets first talk about java 1.7 (or earlier) interface implementation. The main reason behind using an interface is to define a type of user's choice (or vendor's choice). Just like c pr...

Hello geeks, Cloud computing is trending right now. Both provider and consumers are providing and demanding more and more cloud storage and computing resources day by day, which are accessible remotely from anywhere in the world. Tech giant like Google, Microsoft, IBM and others are vying to be go-to provider. But one company remained the leader AMAZON. AWS technologies are behind a lot of services that we use today from a lift, checking your video door bell to watching our favourite shows on netflix, amazon prime, ULLU movies etc. AWS has been one of AMAZON's most profitable business last year. There are approx 2.2 million customers using aws services today. These includes some of the big name like Goldman Sachs, and over 4000+ government agencies. But the challenges for amazon arises here. Most of the users on aws are generating a huge amount of data(in petabytes even in yottabytes) and moving them from one place to other over the internet is the nightmare fo...

Hi there, in this blog post i am going to discuss the basic differences between SCOPE_IDENTITY(), @@Identity and IDENT_CURRENT('tableName').                 Basically all these three are used to retrieve the last inserted identity value in different session and  different scope. Let's try to understand it in detail. SCOPE_IDENTITY() :   It returns the value of identity last inserted within same session and same scope. @@Identity : It is a global variable which returns the value of identity last inserted within same session but in any scope. IDENT_CURRENT('tableName') : It returns the value of identity last inserted in any session and in any scope. Now, i am pretty sure you are wondering about what this session and scope really menu in the above mentioned points.   So, let me clear the same with an example. First we need to create two different but simple table with having the following structure. create table ta...

Hello folks,       I dentity column is very common in database design when we want to add a column as id and auto increment by itself. Some time this same feature is known as auto increment in different database(e.g. MYSQL).  Basically id column is if set as identity(auto increment), is automatically managed and increased by itself when new record(s) are inserted. So, get started with creating a new table in sql server with identity column. Either you can use sql query for this, CREATE TABLE tbl_person ( id INT IDENTITY (1, 1) PRIMARY KEY, name VARCHAR (255) NOT NULL, ); or you can use sql server management studio tool for this. You can set identity option for a column as shown in above screenshot. Here, you can set initial seed(first parameter in sql query) and increment seed (second parameter in sql query). On Successfully creation of table if we try to insert identity column column field explicitly the MSSQL server thro...
