An introduction to Microsoft SQL Server provides an overview of one of the leading relational database management systems (RDBMS) widely used in enterprises. Students delve into the fundamentals of SQL Server, understanding its architecture, functionalities, and capabilities. They learn how SQL Server facilitates efficient data storage, retrieval, and management.

An Introduction to T-SQL Querying focuses on Transact-SQL (T-SQL), the powerful querying language used specifically in Microsoft SQL Server. This course provides a foundational understanding of T-SQL, teaching students how to construct queries to interact with databases effectively. Students learn the syntax, structure, and logic behind T-SQL commands.

This module is focused on writing SELECT queries, learners gain proficiency in crafting precise and effective SQL queries to retrieve data from databases. The course covers the foundational aspects of the SELECT statement, emphasizing its syntax and functionalities.

This module is based on querying multiple tables, students delve into the complexities of retrieving data from multiple related tables in a database using SQL. They learn various techniques to perform joins, such as INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN, understanding how these operations combine data from different tables based on specified conditions. 

This module provides the students to gain expertise in organizing and refining data retrieved from databases. They delve into the use of the SELECT statement along with the ORDER BY clause to sort query results based on specified columns and sorting orders (ascending or descending).

In this module, participants will immerse themselves in the diverse world of SQL Server data types, essential for effective database management. They will explore the intricacies of various data types available within SQL Server, including numeric, character, date and time, binary, and specialized types.

In this module, learners will master the art of Data Manipulation Language (DML) to effectively modify and manipulate data within SQL databases. Students will explore the core DML statements—INSERT, UPDATE, DELETE—to add, modify, or remove data from database tables.

In this course module, students will delve into the extensive range of built-in functions available in SQL, empowering them with powerful tools for data manipulation and analysis. Participants will explore various categories of functions, including string functions, numeric functions, date and time functions, aggregate functions, and more.

In this module, participants will immerse themselves in the powerful concepts of grouping and aggregating data within SQL databases. They'll explore the GROUP BY clause, a fundamental tool for grouping data based on specified columns, enabling the aggregation of information within these groups.

Students will delve into the versatile world of subqueries, a powerful tool in SQL for executing nested queries within a main query. Participants will explore the syntax and applications of subqueries, learning how to use them within SELECT, FROM, and WHERE clauses.

Table expressions, such as Common Table Expressions (CTEs) and derived tables, serve as dynamic tools for creating temporary result sets within SQL queries. Participants will embark on a comprehensive journey through the syntax, benefits, and practical applications of table expressions.

In this module, students will explore the dynamic realm of set operators in SQL, essential for combining and manipulating datasets to derive meaningful insights. Set operators, including UNION, UNION ALL, INTERSECT, and EXCEPT, enable users to merge, compare, and extract data from multiple queries or tables.

Participants will immerse themselves in the world of stored procedures, a powerful feature in SQL databases for encapsulating and executing sets of SQL statements. Students will explore the creation, execution, and management of stored procedures, understanding their role in enhancing code reusability, maintainability, and security within databases.

In this module, students will explore the critical aspects of error handling and transactions in SQL, crucial for maintaining data integrity and reliability within databases. Participants will delve into error handling mechanisms, understanding how to anticipate, capture, and manage errors that may occur during SQL queries or database operations.
