Sometimes, you need to get data from SQL Server that falls between two specific dates or times, like finding all orders placed within a week or all activities that happened during a certain time frame. Writing the right query can be challenging if you're not familiar with how to filter data by date and time. In this article, we will show you how to easily select data between two dates and times in SQL Server using simple queries. Steps to Write Queries for Selecting Data Between Dates and Times As we're going to write queries to filter data ... Read More
In SQL, there are several ways to achieve this, including using LEFT JOIN, NOT EXISTS, and NOT IN. This article will explore these methods in detail, providing examples and guidance on when to use each approach. Using LEFT JOIN with IS NULL Using NOT EXISTS Using NOT IN 1. Using LEFT JOIN with IS NULL The LEFT JOIN operation returns all records from the left table (the first table) and the matching records from the right table (the second table). When no match is found, ... Read More
To insert a node in a linked list using JavaScript, how can we do it? A linked list consists of nodes, each storing data and a reference to the next node. We can insert a new node at various positions: the beginning, a specific position, or the end of the list.. In this article, we'll guide you through how to insert a new node into a linked list in JavaScript, including adding a node at the start, a specific position, or the end. Example Input 1: list = 1 -> 2 -> 3 -> 4 -> 5 -> null; ... Read More
To check if a given year is leap year, We have used two approaches in this article. A leap year has 366 days. In every 4th year, an additional day is added to the month of February to synchronize it with astronomical year. In this article, we are given with two years to check. Our task is to write a JavaScript program to check if a given year is leap year. Approaches to Check Leap Year Here is a list of approaches to check if a given year is leap year in Javascript which we will be discussing ... Read More
In this article, we will learn to prepend a string into all the values of an array in JavaScript. Arrays are versatile data structures used to store multiple elements of similar or mixed types. A common operation is prepending a string to each element of an array, which involves adding a specified string at the beginning of each element. Problem Statement The problem statement can be deeply visualized as given a string text specifically to prepend or attach at the beginning of each element of the array , the output should return the new resultant array with prepended string value ...

In this article, we will learn to initialize a list in Java. A list is an ordered collection that allows us to store and access elements sequentially. It contains index-based methods to insert, update, delete, and search the elements. It can also have duplicate elements. Problem Statement Given a scenario where you need to create and initialize a list in Java, the goal is to understand and implement various approaches to initialize lists effectively. Input Initialize an empty list and add elements − "Apple", "Banana", "Cherry" Output ["Apple", "Banana", "Cherry"] Different Approaches Following are the different approaches to Initialize ...

In this article, we will learn to extract every nth element from an array and display a fixed number of values in Javascript. The objective is to filter out every second element (or more generally every nth element) from an array and limit the result to a specified count of elements. We will explore different approaches in JavaScript for achieving this functionality, each offering a unique way to solve the problem. Problem Statement Let's say you have an array that takes every nth element. Display a fixed number of values after extracting the elements. Input Let’s say the following is ... Read More
