What Will You Learn?
Learn about transactions, why they are important, and how you can use this.
Optimise queries, so that your database runs faster
Evaluate the use of row-based operations vs. set-based operations
Learn what XML data is, how to import and export it, and how to query and manage XML data.
This course is the foundation for the Microsoft Certificate 70-461: “Querying Microsoft SQL Server 2012”.
In Sessions 1 and 2, we learned all about dates, strings and number data types and DML statements. In sessions 3 and 4, we created views, procedures, triggers, constraints and combining datasets, and in session 5 and 6 we learned about ranking and aggregate functions, sub-questions, functions and dynamic SQL.
In this session we’ll be looking at transactions, seeing how to explicitly start and end them, and finding out how they can block other users in the database. Then we’ll see about how to indexes and their role in optimising queries. We’ll also see how we can use Dynamic Management Views to see how we can improve our use of indexes.
We’ll then look at how to write a cursor, and when to use this row-based operation, and the impact of using scalar UDFs. Finally, we’ll investigate XML data – how to convert SQL Server data into XML and vice versa.
No prior knowledge other than what we covered in Sessions 1 to 6 is required. This course builds on the knowledge previously gained in those previous sessions.
There are regular quizzes to help you remember the information.
Once finished, you will know what how to create transactions, indexes, cursors, XML data and more, and we’ll have expanded on our current knowledge of T-SQL.
