ORACLE PL/SQL Fundamentals Training Course

Overview:

Introduction:

This 5-day course gives an introduction to ORACLE PL/SQL, an application development environment that enables the writing of stored procedures, functions, and triggers using both SQL and PL/SQL commands. The course takes the format of a workshop, with a mix of lectures, working examples, and practical exercises. 

Course Objectives:

At the end of this course, the participants will be able to:

  •  Handle runtime errors
  •  Describe stored procedures and functions
  •  Use cursors to process rows
  •  Design PL/SQL anonymous block that executes efficiently
  •  Describe the features and syntax of PL/SQL,
  •  Use PL/SQL programming constructs and conditionally control code flow (loops, control structures, and explicit cursors)
  •  Check index fragmentation and maintain them.

 

Targeted Audience:

  • Anyone who wants to start a career in SQL database administration
  • Anyone who wants to have complete SQL database training to get a job in IT
  • Anyone who wants to advance his/her career
  • Anyone who wants to master the SQL command-line skills
