EXCEPTIONAL TRAINING COURSES FOR IT PROFESSIONALS
LONDON UK | ONSITE | ONLINE
The JBI Oracle SQL training course provides a thorough introduction to SQL language coding. Basic features are covered in detail, and then the course moves on to more advanced topics such as wide selection of scalar and group functions, group by, SQL Joins (including ANSI standard join syntax) and correct use of union, intersect and minus. The course finishes with introducing main-line approaches to using DML (insert, update and delete) plus a simple review of basic DDL (creating tables, indexes, plus use of primary keys and foreign keys. Delegates are encouraged to work with the lecturer in class, trying smaller demo techniques, and then going on to more interesting coding challenges in a set of exercises. Often skeleton code is available, so code adaption is possible (thus mimicking common coding practice).
