70-461 Session 6: Querying Microsoft SQL Server 2012

Course details

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

In Sessions 1 and 2, we learned all about dates, strings and number data types and DML statements. In sessions 3 and 4, we created views, procedures, triggers, constraints and combining datasets, and in session 5 we learned about ranking and aggregate functions.

We'll will now be creating sub-queries, working through objectives 7b-e of the exam 70-461. We'll be created correlated subqueries, where the results of the subquery depend on the main query. We'll be looking at Common Table Expressions using the WITH statement, and we'll be using what we have learned to solve a common business problem.

We'll be looking at functions (objective 14), including the three different types of User Defined Functions (UDF): scalar functions, inline table functions, and multi-statement table functions. We'll then complete objective 6 by looking at synonyms and dynamic SQL, and objective 8 by looking at the use of GUIDs. We'll also look at sequences.

No prior knowledge other than what we covered in Sessions 1 to 5 is required. This course builds on the knowledge previously gained in those previous sessions.

There are regular quizzes to help you remember the information.

Once finished, you will know what how to write subqueries, functions, sequences and more, and we'll have expanded on our current knowledge of T-SQL.
