Welcome to our blog series on SQL Server concepts and ideas! Whether you are a beginner looking to build expertise in SQL Server programming or a seasoned developer wanting to refresh your knowledge, this series is for you. We will cover important concepts thoroughly, going beyond just exam preparation and focusing on practical learning.
Introduction to SQL Server Security
Let’s start by understanding some basic definitions. In a workplace scenario, think of a “securable” as a resource that someone might want to access, like a folder. A “principal” refers to anything that might want to gain access to the securable, such as a user. And a “permission” is the level of access a principal has to the securable, like read or write access. In this blog post, we will dive deeper into SQL Server security and explore different aspects of it.
Introduction to Hierarchical Query
Have you ever wondered how to work with hierarchical data in SQL Server? A Common Table Expression (CTE) can be thought of as a temporary result set and is a powerful tool for handling hierarchical queries. In this blog post, we will explore the concept of CTEs and how they can be used to simplify complex hierarchical queries.
Introduction to Basics of a Query Hint
Query hints are a way to specify that certain optimizations or behaviors should be used throughout a query. While they can be useful in certain scenarios, it is important to use them judiciously. In this blog post, we will discuss the basics of query hints and when it is appropriate to use them.
Introduction to SQL Error Actions
When an error occurs in SQL Server, it is commonly believed that the remaining SQL statements will not be executed. However, there are exceptions to this rule. In this blog post, we will explore these exceptions and discuss how to handle errors effectively in your SQL code.
Introduction to XML Data Type Methods
The XML data type in SQL Server allows you to store and manipulate XML data. With the power of the XQuery language, you can analyze and query the values contained in your XML instances. In this blog post, we will introduce the XML data type and explore its various methods and functionalities.
