Oracle 11g PL/SQL
Introduction to Oracle 11g PL/SQL Programming training, candidates learn the environment and context in which PL/SQL operates. Develop logic within PL/SQL program blocks, user defined functions, procedures, packages, triggers,
handle program exceptions. We give special care to every candidates to complete the hands-on lab exercises on each topic.
