By the end of this module, you will have a solid understanding of the fundamental concepts of SQL Server and database management. This knowledge will serve as a foundation for the more advanced topics we will cover in subsequent modules.

Module 2: SQL Fundamentals: SELECT, INSERT, UPDATE, DELETE

This is where the real fun begins! You'll learn the core SQL commands: SELECT (to retrieve data), INSERT (to add data), UPDATE (to modify data), and DELETE (to remove data). We’ll explore how to write these queries effectively, using various clauses and conditions. You will also learn how to use these commands with different data types, such as integers, strings, dates, and booleans. We will cover the syntax and usage of each command in detail, providing plenty of examples and exercises to help you practice. For example, you will learn how to use the SELECT command to retrieve specific columns from a table, filter the results using WHERE clauses, and sort the results using ORDER BY clauses. You will also learn how to use the INSERT command to add new rows to a table, the UPDATE command to modify existing rows, and the DELETE command to remove rows. Furthermore, we will cover the concept of transactions and how to use them to ensure data integrity. You will learn how to start a transaction, execute multiple SQL commands within the transaction, and either commit the transaction to save the changes or roll back the transaction to undo the changes. By the end of this module, you will be able to write basic SQL queries to retrieve, add, modify, and delete data in a SQL Server database.

Module 3: Filtering and Sorting Data

How do you find exactly what you're looking for in a huge database? We’ll teach you how to use WHERE clauses, comparison operators, logical operators (AND, OR, NOT), and the ORDER BY clause to filter and sort your data. You will also learn how to use wildcards, such as % and _, to match patterns in your data. We will cover the syntax and usage of each operator and clause in detail, providing plenty of examples and exercises to help you practice. For example, you will learn how to use the WHERE clause to filter rows based on specific conditions, such as filtering customers by their location or filtering products by their price range. You will also learn how to use the ORDER BY clause to sort the results in ascending or descending order based on one or more columns. Furthermore, we will cover the concept of indexing and how it can improve the performance of your queries. You will learn how to create indexes on specific columns to speed up the retrieval of data. By the end of this module, you will be able to write complex SQL queries to filter and sort data in a SQL Server database, allowing you to find exactly what you need quickly and efficiently.

Databases are all about relationships! You'll master different types of SQL joins (INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL OUTER JOIN) to combine data from multiple tables. We'll explain how to identify and create relationships between tables. You will also learn how to use aliases to simplify your queries and make them more readable. We will cover the syntax and usage of each type of join in detail, providing plenty of examples and exercises to help you practice. For example, you will learn how to use INNER JOIN to retrieve rows that have matching values in both tables, LEFT JOIN to retrieve all rows from the left table and the matching rows from the right table, and FULL OUTER JOIN to retrieve all rows from both tables. Furthermore, we will cover the concept of foreign keys and how they are used to enforce referential integrity. You will learn how to create foreign key constraints to ensure that the relationships between tables are maintained correctly. By the end of this module, you will be able to write complex SQL queries to combine data from multiple tables, allowing you to gain valuable insights from your data.
