About this course

In this SQL Programming training course, you learn how to optimize the accessibility and maintenance of data with the SQL programming language, and gain a solid foundation for building, querying, and manipulating databases. It will describe the standardlanguage, but also identify deviations from the standard in two widely-used database products, Oracle and Microsoft SQL Server.Choose between working with the PostgreSQL database product or Microsoft SQL Server as you practice these skills with the hands-on exercises.

Target Audience

No previous experience required. This course was designed to teach you the fundamentals of the SQL language. You will learn SQL over 3 days with instructor-led training and hands-on experience using either the PostgreSQL database product or Microsoft SQL Server 2016.
