Course Description
When working with SQL, being able to pull the right data is the key to effective business operations. This course on "Intermediate MySQL" will expand your skills in setting up queries to pull the right data in the right ways for your reports. Learn how to retrieve data using different statements like SELECT or WHERE, string functions, and sorting. Learn how to create views so you can see at-a-glance data, and learn how to group and merge data, too. Come away from this course knowing how to more precisely query your data for more accurate reports.
So you've mastered the basics of SQL. If you want to do more specific data pulls to get more detailed reports tailored to your business needs, this course will broaden your skills in knowing how to use SQL to report data. This course will show you new statements to use, like SELECT, WHERE, LIKE, and IN to retrieve more drilled-down data. You'll also learn how to query across databases, and understand how to normalize your database to reduce redundancy and increase efficiency. Learn how to nest or intersect data when setting up queries as well. Finally, learn how to create your own custom variables and functions so you can get the data you need quickly and accurately. The instruction in this course will not only help you grow your technical knowledge, but can help you grow your career as well.
