This course is the foundation for the Microsoft Certificate 70-461: “Querying Microsoft SQL Server 2012” and 70-761 “Querying Data with Transact-SQL”. Please note – these certificates are no longer being offered by Microsoft. However, the exam requirements allow you to have a good understanding of T-SQL.
It also will help with the current exams DP-300 (Azure Database Administrator Associate) and DP-600 (Implementing Analytics Solutions Using Microsoft Fabric) Please note: This course is not affiliated with, endorsed by, or sponsored by Microsoft.
Session 1
The basics presented are: how to install SQL Server, and how to create and drop tables.
We then try to create a more advanced table, but find that we need to know more about data types – so we go into some detail about data types and data functions, the foundation of T-SQL.
Session 2
We’ll create tables which use these, and then INSERT some data into them. Then we’ll write queries which will retrieve and summary this data, using SELECT, FROM, WHERE, GROUP BY, HAVING and ORDER BY.
We’ll then JOIN these tables together to find where we are missing data and where we have inconsistent data. We’ll then UPDATE and DELETE data from the tables.
Session 3
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.
