describe PL/SQL and explain the difference between SQL and PL/SQL and why PL/SQL is necessary;
code PL/SQL anonymous blocks using Oracle Application Express;
apply PL/SQL syntax and lexical units including PL/SQL variables, constants, functions, data types, and nested blocks to the development of business application development;
expand on the use of Data Manipulation Language (DML) to add, update, delete or merge data in the database by using implicit cursors and their attributes and how to group SQL statements for database transaction processing;
use conditional control statements and iterative control statements to direct the flow of execution through a program;
implement PL/SQL explicit cursors to allow multiple row retrieval from a database and programming code to process rows one at a time;
code an exception handler so that programs do not terminate when PL/SQL raises an exception;
