Course overview

This 5-day course is an introduction to SQL, relational database principles, and the HP NonStop™ SQL/MX product and serves as a prerequisite to more advanced NonStop SQL/MX courses. Hands-on lab sessions provide practical experience with generating SQL/MX queries to access data and creating database objects (catalogs, tables, indexes, views, and constraints).


Prerequisites

  • Concepts and Facilities course (U4147S)

Audience

  • Anyone requiring an introduction to SQL and working with the NonStop SQL/MX product
