Microsoft SQL Server Programming 5 Days

Course Overview

This 5-day course is intended for students new to querying and programming with Microsoft SQL Server products who need a total immersion in the subject on a SQL Server 2016 or 2017 platform. This is a very comprehensive and intensive course with plenty of illustrated examples and augmented with practical hands-on exercises to enhance the learning experience.

Applies to all versions from SQL Server 2012 through to Server 2022.

DURATION: 5 days

INTRODUCTION

Additionally, with the course structure being fully modularised, customised versions of this course can also be devised and delivered to suit individual requirements. In fact, specific content from this course could also be combined with material from other related courses to produce a bespoke training package – just ask for details.
