• Introduction to PL/SQL
• Explain the need for PL/SQL
• Explain the benefits of PL/SQL
• Identify the different types of PL/SQL blocks
• Output messages in PL/SQL
• Declaring PL/SQL Variables
• Recognize valid and invalid identifiers
• List the uses of variables, declare and initialize variables, use bind variables
• List and describe various data types using the %TYPE attribute
• Writing Executable Statements
• Identify lexical units in a PL/SQL block
• Use built-in SQL functions in PL/SQL and sequences in PL/SQL expressions
• Describe when implicit conversions take place and when explicit conversions have to be dealt
with
• Write nested blocks and qualify variables with labels
• Write readable code with appropriate indentation
• Interacting with the Oracle Database Server
• Create PL/SQL executable blocks using DML and transaction control statements
• Make use of the INTO clause to hold the values returned by a SQL statement
• Writing Control Structures
• Identify the uses and types of control structures (IF, CASE statements and expressions)
• Construct and identify loop statements
• Apply guidelines when using conditional control structures
• Working with Composite Data Types
• Create user-defined PL/SQL records
• Create a record with the %ROWTYPE attribute
• Create an INDEX BY table and INDEX BY table of records
• Describe the differences among records, tables, and tables of records
• Using Explicit Cursors
• Distinguish between usage of implicit and explicit cursors, use SQL cursor attributes
• Declare and control explicit cursors, use simple loops and cursor FOR loops to fetch data
• Declare and use cursors with parameters
• Lock rows with the FOR UPDATE clause and reference the current row with the WHERE
CURRENT OF clause
• Handling Exceptions
• Define PL/SQL exceptions
• Recognize unhandled exceptions
• Handle different types of exceptions (pre-defined exceptions, non-predefined exceptions and
user-defined exceptions)
• Propagate exceptions in nested blocks and call applications
• Creating Stored Procedures and Functions
• Differentiate between anonymous blocks and subprograms
• Create a simple procedure and invoke it from an anonymous block
• Create a simple function
• Create a simple function that accepts a parameter
• Differentiate between procedures and functions
