Monde says: Its was nice the lecture made clear to the point examples and I could make sense of what he was explaining example was making sense about all the aggregate clauses such as SUM, MIN, COUNT and AVG and MAX he was too good I like him

Jay says: I learned SQL years ago, and I needed a refresher on the basic syntax. This course was perfect for that purpose!

In this course, we will look in an hour at the SELECT statement.

There are six constituent clauses in this statement: 

• SELECT - this is akin to the Print statement in other languages, and

• FROM - this shows your data source,

• WHERE - this filters down your data source,

• GROUP BY - this enables the results to be summarised,

• HAVING - this filters the summary, and

• ORDER BY - this sorts your results.

We will then look at saving your code using both views and procedures.

Finally, we'll export your reports into Excel, both statistically (copy and paste) and dynamically (so that you always have the latest reports).

In just an hour, you'll be able to create your own SELECT statements, so you can use them in SQL Server (SSMS, SSRS and SSIS) and in Excel. This is all you need to start writing and using your own code. Quick and easily.

If you have not already got SQL Server installed on your machine, this course includes a link to a video which shows you how you can install for free SQL Server Developer edition, together with SQL Server Management Studio (SSMS). These can be installed on your laptop or desktop to use for learning purposes for as long as you need.

Knowledge of this will also help with the DP-300 and DP-600 exams.
