In this course you will learn the PL/SQL programming language. You will also learn how to create PL/SQL blocks of application code, how to use various features of PL/SQL, how to write anonymous blocks of code in PL/SQL, how to use various PL/SQL conditional constructs and loops in program blocks, how to interface the PL/SQL code with the database, how to use stored procedures and functions in their program blocks and how to handle Exceptions in PL/SQL code.
This course is aimed at Database Administrators, Forms Developers, PL/SQL Developers, Portal Developers, System Analysts and Technical Consultants.
Upon completion you will know how to:
- Design PL/SQL anonymous block that execute efficiently;
- Use PL/SQL programming constructs and conditionally control code flow (loops, control structures, and explicit cursors);
- Handle exceptions in the program units;
- Create and execute simple stored procedures and functions;
- Write PL/SQL code to interface with the database;
- Describe the features and syntax of PL/SQL.
