SQL Server 2016 Pt 7 - Computed Columns

Posted by Andrew Gould on 10 November 2016

A computed column in a SQL Server table allows you to store an expression which calculates a new value based on the data in other columns of the same table. This video explains how to create computed columns and how to persist the result of the calculation so that it's stored in the table. You'll also learn a little about SQL Server's expression syntax, including how to use some of its built-in functions, the difference between deterministic and non-deterministic functions, how to use Case expressions to test conditions and how to concatenate strings. We'll do this by building a few example computed columns including constructing a full name from first and last name columns, calculating age in days using the DateDiff function and calculating age in years using DateDiff, DateAdd and a Case expression.

SQL Server 2016 Pt 6 - Designing and Creating Relational Databases

Posted by Andrew Gould on 10 November 2016

Creating the optimal design for relational database can be a long and complex process - this video takes you through the key steps of normalising data including identifying repeating values, creating separate tables to store those values, and creating primary keys, foreign keys and relationships. The video also includes a section drawing database diagrams, which is the most fun you can have when designing a database!

SQL Server 2016 Pt 5 - Basic Table Design, Data Types and Constraints

Posted by Andrew Gould on 10 November 2016

Designing basic tables in SQL Server involves deciding which columns the table should include, what the data type of those columns should be (not always an easy choice!) and a few additional properties such as whether the column can be left empty (or NULL) and whether there should be any constraints on the values entered into the column. This video takes you through that process to design and create a simple table to store information about people. The video contains a discussion of the main text, number and date data types in SQL Server - you'll learn the difference between char, varchar, nchar and nvarchar data types, as well as the difference between exact and approximate numerics. The video also covers the basics of inserting and editing data before the final part shows how to automatically generate scripts that will recreate the table and its precious data in the event that you delete it.
