Synopsis

This introductory SQL training course will introduce you to relational databases (RDBMSs), and SQL (Structured Query Language) - the language used to create, modify, manage and query them. Using real world examples you will use SQL to create tables, set permissions, insert, update and delete data. You'll also retrieve your data using standard SQL. You will also learn about the most common features of the proprietary extensions to the standard SQL language supported by the two most common databases - Microsoft SQL Server and Oracle.
