What Will You Learn?
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”
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.
