SQL Programming
Price: Contact SST for pricing | Duration: 3 days
Prerequisites: General computer knowledge. Familiarity with relational database concepts is helpful but not required.
Description: This SQL programming course teaches students relational database fundamentals and SQL programming skills. Topics covered include relational database architecture, database design techniques, and simple and complex query skills. This class is intended for analysts, developers, designers, administrators, and managers new to the SQL programming language. Upon completion, participants will understand SQL functions, join techniques, database objects and constraints, and will be able to write useful SELECT, INSERT, UPDATE and DELETE statements. Extensive hands on exercises are used throughout to reinforce learning and develop real competency.
The information in this course is also contained in the SQL Server Administration and SQL Server Developer courses. Students requiring those additional skills should register for those courses instead.
