This SQL video course includes 4 labs
This comprehensive lab provides step-by-step guidance on the fundamentals of SQL statements and functions to filter, aggregate, and analyze data.
Here’s what you can expect to:
Learn how to use SELECT statements to retrieve data from specific columns in a database table. This includes selecting individual columns, selecting all columns using the wildcard, and using aliases to name columns.
Learn how to use the WHERE clause to apply conditions and filter rows based on specific criteria. This involves using logical operators (AND, OR, NOT) and comparison operators (equals, not equals) to narrow down the data results
Learn how to use the GROUP BY clause to group rows based on one or more columns. This allows you to perform aggregate functions like counting, summing, averaging, and finding minimum or maximum values within each group.
Learn how to use the ORDER BY clause to sort the results of your queries in either ascending or descending order based on one or more columns.
The hands-on challenge or capstone project will provide you with a practical application of the concepts learned. You will apply your skills in querying data from the Northwind database as a sales executive, using basic SQL clauses such as SELECT, GROUP BY, and WHERE.
