70-461 Session 4: Querying Microsoft SQL Server 2012

Building on sessions 1 to 3, we’ll merge databasets together, create procedures and incorporate error handling.
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, JOINed multiple tables together and used DML commands, and in Session 3 we created views, constraints and triggers to encapsulate language and improve security.

We will further encapsulate our routines by creating procedures, allowing us to EXECUTE parameterised commands with just one statement, and we’ll add some error handling with TRY, CATCH and THROW.
