Online Class: Introduction to SQL

Structured query language (SQL) is the language of databases. Whether you run reports or provide a dynamic website, you need to know SQL to add, delete, edit and view records. Databases organize and collect your data, and the SQL language is the liaison between you and the data. The role of database administrator includes several functions that you should know. You should know how to create and design tables, manipulate your data and run reports, create small programs (stored procedures) and use more advanced concepts such as transactional support and cursors.

This course provides a step-by-step overview and instructions that help you get started with the SQL language. We use MSSQL, but you can use this course to get started with understanding data structures and techniques for all SQL engines including Access, Oracle and MySQL. We show you how to create SQL statements including SELECT, DELETE, UPDATE and INSERT. Then, we show you how to create and design tables. We show you how to create stored procedures, which allow you to run the same SQL statement multiple times without reprogramming your database. Finally, we show you how to use cursors, use transactions to preserve data integrity, and creating views for larger data sets.

Whether you're new to database administration or want to create customized, personal reports for your online business, this course shows you how to get started and helps you understand the SQL language from the ground up.
