SQL Server 2016 Querying Data For Report Developers Duration: 3 Days

Course Overview

Introduction A brief overview of the course This course is intended for students who need to familiarise themselves with the various querying techniques available to retrieve data from a Microsoft SQL Server database in a report authoring environment, whether that be through an implementation of Microsoft SQL Server Reporting Services or similar reporting tool. No previous knowledge of the SQL language is assumed as the course is designed from the ground up, starting with basic queries and advancing to more complex querying methods. The last module (which is optional) will also give students the opportunity to put their SQL skills into practice by creating a simple report. On completion of the course students will be able to retrieve data using the SQL language and write effective queries for reporting purposes.

 

 

 

Prerequisites
What you should know before attending this course

Students should ideally be familiar with basic programming concepts.

They should also understand the fundamental design of relational databases including, but not restricted to, the purpose of primary and foreign keys, entity relationships, and data normalization. These prerequisites can be met by taking the 2 day "Microsoft SQL Server 2016 Relational Database Design and Querying Fundamentals" course.

Objectives
What the course sets out to achieve

Upon successful completion of this course, students will be able to:

  • Understand SQL Syntax
  • Retrieve, Filter and Sort Data
  • Work with the SQL Server Date and Time Data Types
  • Query Data from Multiple Tables by Using Joins
  • Summarize and Rank Grouped Data
  • Combine and Limit Result Sets
  • Work with Subqueries
  • Implement Stored Procedures
  • Implement SQL Code to Create a Simple Report
