This course is an outstanding and complete introduction to the NonStop SQL/MP product
and how to embed SQL/MP statmetents into COBOL85 servers.
The course combines the functions of an introduction to SQL/MP
and embedding SQL/MP into servers into a concise 5-day course.
The student will learn how to use SQL/MP to meet the practical needs of today’s
organizations, how to list, modify and delete database items; and how to define
and create databases. The student will become strongly versed in the aspects of
embedding SQL/MP into the server, how to code dynamic SQL statments, and how to use
timestamp and interval datatypes.
Eight extensive hands-on labs will reinforce and anchor the student's classroom learning.
