Intermediate Level

This course is the foundation for the Microsoft Certificate 70-461: "Querying Microsoft SQL Server 2012".

In Session 1, we learned all about dates, strings and number data types, and in Session 2 we constructed SELECT queries using SELECT, FROM, WHERE, GROUP BY, HAVING and ORDER BY, and JOINing multiple tables together.

We'll now use that data to create views, which enable us to store these SELECT queries for future use, and triggers, which allow for code to be automatically run when INSERTing, DELETEing or UPDATEing data.

We'll look at the database that we developed in session 2, and see what is wrong with it. We'll add some constraints, such as UNIQUE, CHECK, PRIMARY KEY and FOREIGN KEY constraints, to stop erroneous data from being added some data. By doing this, we will complete objectives 2, 3, 4 and 5 from the 70-461 exam.

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.

What are the requirements?
You need to know all about data types and functions.
You also need to know about how to create SELECT statements and INSERT, DELETE and UPDATE statements.
If you don't, then you should take my Session 1 or Session 2 course first.
There is a 30-day money back guarantee of this Udemy course.
Why not have a look at the curriculum below and see what you can learn?
What am I going to get from this course?
identify structural problems in databases
create UNIQUE, CHECK, PRIMARY KEY, FOREIGN KEY constraints to more to stop erroneous data from being added.
create views, to allow for encapsulation of SELECT statements and provide higher security.
create triggers, to allow for code to be automatically run after or instead of a DML command.
complete objectives 2, 3, 4 and 5 and work towards other objectives from Microsoft Certification 70-461 "Querying Microsoft SQL Server 2012"
What is the target audience?
This course is for you if want a refresher course in SQL, or are learning SQL for the first time.
This course is for you if you are working towards the requirements for exam 70-461, or if you just want to expand your knowledge of T-SQL.
If you are starting from the beginning, then you should look at my session 1 or 2 courses before taking this session 3.
If you want more advanced topics, then please look at my later sessions.
