Cel szkolenia dlearning

This Oracle Database: Program with PL/SQL training starts with an introduction to PL/SQL and then explores the benefits of this powerful programming language. Through hands-on instruction from expert Oracle instructors, you'll learn to develop stored procedures, functions, packages and more.

Learn To:

  • Conditionally control code flow (loops, control structures).
  • Use PL/SQL packages to group and contain related constructs.
  • Create triggers to solve business challenges.
  • Use some of the Oracle supplied PL/SQL packages to generate screen output and file output.
  • Create anonymous PL/SQL blocks, functions and procedures.
  • Declare PL/SQL Variables.
