SQL Querying: Fundamentals Course Outline

Overview
Organizations use large SQL databases to store information about clients, products, or sales. However, that data is locked into those databases until it is accessed by a business intelligence tool such as Power BI, Tableau or Crystal Reports. With the proper permissions, analysts can use SQL to select the data they need for additional analysis and reporting. This class, SQL Querying: Fundamentals, provides an overview of the SQL commands that can be used to access that data.

You will:
• Connect to the SQL Server database and execute a simple query.
• Include a search condition in a simple query.
• Use various functions to perform calculations on data.
• Organize the data obtained from a query before it is displayed on-screen.
• Retrieve data from multiple tables.

Target Student
This course is intended for individuals with basic computer skills, familiar with concepts related to database structure and terminology, and who want to learn the basics of querying SQL databases using the SELECT statement.

Prerequisites
Some familiarity with database terminology and structure is helpful.
