Description
This course is the foundation for the Microsoft Certificate 70-461: "Querying Microsoft SQL Server 2012/2014". Please note - this certificate is no longer being offered by Microsoft. However, the exam requirements allow you to have a good understanding of T-SQL.We'll start off by creating views, which enable us to store these SELECT queries for future use. We'll add security and create indexed views.We'll then create AFTER and INSTEAD OF triggers, which allow for code to be automatically run when INSERTing, DELETEing or UPDATEing data. We'll look at what happens when triggers run triggers, and how to handle multiple rows in a session.We'll look at the database that we previously developed, and see what is wrong with it. To solve these problems, we'll add some constraints, such as UNIQUE, CHECK, PRIMARY KEY and FOREIGN KEY constraints. This will stop erroneous data from being added some data.No prior knowledge other than what we covered in Sessions 1 and 2 is required. However, prior experience with Excel or Access would be beneficial.There are regular quizzes to help you remember the information.Once finished, you will know what how to write triggers, views and constraints, and we'll have expanded on our current knowledge of T-SQL.
