SQL TSQL Developer

This course is designed to provide you with the essential skills needed to become a proficient SQL and T-SQL developer. You will learn how to write efficient SQL queries, design and manage databases, and use T-SQL (Transact-SQL) for advanced data manipulation and analysis in Microsoft SQL Server environments. SQL is the foundation for managing relational databases, and T-SQL is a powerful extension of SQL that allows for more complex operations and automation.

Throughout this course, you will gain hands-on experience with writing SQL queries, designing normalized databases, creating stored procedures, functions, triggers, and handling transactions. You’ll also dive into performance optimization, error handling, and debugging—critical skills for any SQL developer. This course is ideal for individuals looking to pursue careers as database developers, data analysts, or back-end developers.

By the end of the course, you’ll have the skills and knowledge required to manage and manipulate data efficiently and be ready to work with real-world SQL databases.

What You’ll Learn

• SQL Basics
  Understand the fundamentals of Structured Query Language (SQL). You will learn how to retrieve, insert, update, and delete data from a relational database using SELECT, INSERT, UPDATE, and DELETE statements.
• Database Design & Normalization
  Learn how to design a relational database, create tables, define primary and foreign keys, and normalize data to eliminate redundancy. You’ll understand the principles behind the various normal forms (1NF, 2NF, 3NF).
• Advanced SQL Queries
  Master complex SQL queries, including joins (INNER, LEFT, RIGHT, FULL), subqueries, set operations (UNION, INTERSECT, EXCEPT), and grouping data using aggregate functions (SUM, COUNT, AVG, etc.).
• T-SQL Programming
  Dive into T-SQL, the Microsoft extension to SQL. Learn how to write stored procedures, functions, triggers, and work with variables. You’ll also explore error handling with TRY…CATCH, and how to manage transactions to ensure data integrity.
• Data Manipulation & Transactions
  Gain a deep understanding of how to work with transactions in SQL, including COMMIT, ROLLBACK, and SAVEPOINT. Learn how to ensure data consistency and deal with concurrency issues using isolation levels and locks.
• Indexes & Performance Optimization
  Learn how to design and use indexes to speed up query performance. You’ll explore strategies for optimizing SQL queries, identifying bottlenecks, and improving database performance.
• Views, Triggers, and Stored Procedures
  Understand how to create and use views to simplify complex queries, automate actions with triggers, and write reusable stored procedures to encapsulate logic.
• SQL Server Management Tools
  Get familiar with Microsoft SQL Server Management Studio (SSMS) and other database tools to connect to, manage, and maintain SQL Server databases.
• Database Security
  Learn about database security principles, including user authentication, role-based access control, and encryption methods to ensure that sensitive data is secure.
• Backup, Recovery, and Data Integrity
  Understand how to back up and restore databases in SQL Server, maintain data integrity, and recover from failures using tools like SQL Server Management Studio.
