4. Writing Control Structures

Identify the uses and types of control structures (IF, CASE statements and expressions)
Construct and identify loop statements
Use EXIT and CONTINUE statements inside loops

5. 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, collections, and collections of records
Initialize collections and records

6. Using Explicit Cursors

Distinguish between implicit and explicit cursors and 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

7. Handling Exceptions

Define PL/SQL exceptions
Recognize unhandled exceptions
Handle different types of exceptions (internally defined exceptions, predefined exceptions and user-defined exceptions)
Propagate exceptions

8. Using PL/SQL Subprograms

Differentiate between anonymous blocks and subprograms
Create a simple procedure and invoke it from an anonymous block
Identify benefits of subprograms

9. Creating Procedures and Using Parameters

Create a procedure with parameterrs
Use named notation
Work with procedures (create, invoke and remove procedures)
Handle exceptions in procedures and display a procedure's information

10. Creating Functions

Differentiate between a procedure and a function
Describe the uses of functions
Work with functions (create, invoke and remove functions)

11. Creating Packages

Identify the benefits and the components of packages
Work with packages (create package specification and body, invoke package subprograms, remove a package and display package information)
Overload package subprograms and use forward declarations

12. Working with Packages

Use package types and variables
Use packaged constants and functions in SQL
Use ACCESSIBLE BY to restrict access to package subprograms

13. Using Dynamic SQL

Describe the execution flow of SQL statements
Use Native Dynamic SQL (NDS)
Bind PL/SQL types in SQL statements

14. Design Considerations for PL/SQL Code

Create standard constants and exceptions
Write and call local subprograms
Control the run-time privileges of a subprogram
Perform autonomous transactions
Use NOCOPY hint, PARALLEL ENABLE hint and DETERMINISTIC clause
Use bulk binding and the RETURNING clause with DML

Describe the PL/SQL compiler and features
Use the PL/SQL compiler initialization parameters
Use the PL/SQL compile time warnings

17. Managing PL/SQL Code

Describe and use conditional compilation
Code-based access control: granting roles to program units
Whitelist code access with the ACCESSIBLE BY clause
Mark code as deprecated
