SQL Server: Data Manipulation and Transactions

Ready to move beyond querying data and start actively managing it? Learning to correctly insert, update, and delete records is the critical next step in your SQL Server journey. This course provides a practical guide to Data Manipulation Language (DML) and transaction management. You will progress from simply reading data to confidently modifying it, all while learning professional techniques to ensure data integrity and handle potential errors. By the end, you'll be able to perform data modifications safely and understand how to manage concurrent operations in a multi-user environment. What you'll learn: - Learn to add, change, and remove data using the core INSERT, UPDATE, and DELETE statements. - Apply transaction control with BEGIN, COMMIT, and ROLLBACK to ensure atomic and consistent data changes. - Understand the fundamental ACID properties that guarantee reliable database transactions. - Implement robust error handling within your T-SQL scripts using TRY...CATCH blocks. - Use the powerful MERGE statement to efficiently handle combined insert, update, and delete logic. - Structure complex data modifications cleanly using Common Table Expressions (CTEs). - Explore transaction isolation levels to manage and prevent common data concurrency issues. The course begins with the fundamentals of each DML statement before progressing to the principles of transaction management, error handling, and more advanced data modification patterns. This course is designed for those who have a basic understanding of writing SQL SELECT queries and are ready to learn how to modify data. No prior experience with DML or transactions is required.
