Oracle 1Z0-149 Syllabus Topics:

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 and %ROWTYPE attributes
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
Writing SQL in PL/SQL	- 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 - Use EXIT and CONTINUE statements inside loops
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
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
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
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
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
Creating Functions	- Differentiate between a procedure and a function - Describe the uses of functions - Work with functions (create, invoke and remove functions)
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
Working with Packages	- Use package types and variables - Use packaged constants and functions in SQL - Use ACCESSIBLE BY to restrict access to package subprograms
Using Dynamic SQL	- Describe the execution flow of SQL statements - Use Native Dynamic SQL (NDS) - Bind PL/SQL types in SQL statements
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
Creating Compound, DDL, and Event Database Triggers	- Create triggers on DDL statements - Create triggers on system events - Describe different types of triggers and their uses
Using the PL/SQL Compiler	- Describe the PL/SQL compiler and features - Use the PL/SQL compiler initialization parameters - Use the PL/SQL compile time warnings
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
Managing Dependencies	- Track and manage procedural dependencies
