SQL EXISTS – Exploring EXISTS Operator in SQL Server

SQL Exists is a conditional operator that checks the existence of rows in a subquery. It returns true if the subquery returns at least one row and false if it returns no rows.

SQL Exists is often used in conjunction with other conditional operators such as WHERE, HAVING, and SELECT.

In this article, we will explore the basics of SQL Exists and show you how to use it in your queries. We will also use some examples and best practices for working with SQL Exists.

Mastering Design Patterns in C#: Best Practices for High-Quality Code (2023)

Design Patterns are a set of reusable solutions to commonly occurring problems in software design. They are not a finished design that we can transform directly into code but rather a guide for solving problems.

The goal of using Design Patterns is to increase the efficiency and effectiveness of software development and provide a common vocabulary for developers to discuss design solutions.



C# switch Statement (With Examples)

The switch statement lets you choose which code block to execute from among many options.
A switch statement evaluates an expression and executes the code corresponding to the expression’s matching value.

It is similar to if-else statements but with a few key differences. This article will explore the C# switch statement and its various use cases.

SQL Server CONVERT Function: How to Convert Data Types in SQL Server

As a SQL Server developer, you may encounter situations where you must convert data types from one form to another. The SQL Server CONVERT function can help you achieve this task by changing the data type of an expression to another data type.

This article will cover everything you need to know about the SQL Server CONVERT function. I’ll explain the function and how to use it and provide code examples in SQL Server. We’ll also compare the CONVERT function to similar functions in SQL Server, like CAST, FORMAT, and PARSE.



C# Operators with [Examples]

In C#, operators are special symbols or characters used to perform specific operations on one or more operands. These operators help in manipulating data and performing various computations on them.

C# has a wide range of operators, such as assignment, arithmetic, relational, logical, unary, ternary, bitwise, and compound assignment operators. Understanding and using these operators correctly is crucial for effective programming in C#.

Stored Procedure in SQL Server – A Complete Guide [with Examples]

If you’re working with SQL Server, you may have come across the concept of stored procedures. A stored procedure is a precompiled set of SQL statements that we can save in the database for later use. Once it is created, we can execute it multiple times without recompiling the code. 

This article aims to cover everything you need to know about stored procedures in SQL Server, including benefits, creation, modification, and exception handling.

SQL Server TRY_CAST() Function – Understanding TRY_CAST() in SQL with [Examples]

TRY CAST function in SQL belongs to the Conversions category of functions and resembles the CAST() function. Its purpose is to transform an expression from one data type to another. If successful, the result will be the expression in the expected data type, but if it fails, the function will return null.

This blog post will dive into the TRY_CAST() function in SQL Server, its syntax, and how it differs from the CAST() function. We will use a few code examples to make it easy to implement this function in our SQL Server database.
