Oracle PL/SQL Programming

Alert Me

Description

Increase the productivity, performance, scalability, portability, and security of your Oracle database with this comprehensive PL/SQL programming course. With this training, you learn to write PL/SQL programs, build stored procedures, design and execute modular applications, and increase the efficiency of data movement — essential skills for any Oracle developer.

Outline

Introduction and Overview

PL/SQL fundamentals

  • Declaring and anchoring variables to database definitions
  • Flow control constructs

Oracle 11g and 12c PL/SQL features

  • PL/Scope in Oracle 11g
  • Returning implicit cursor results from stored procedures in Oracle 12c
  • Declaring local functions within SELECT statements in Oracle 12c

Data Manipulation Techniques

Maintaining data with DML statements

  • Employing the RETURNING INTO clause
  • Solving the fetch-across-commit problem

Managing data retrieval with cursors

  • Implications of explicit and implicit cursors
  • Simplifying cursor processing with cursor FOR LOOPs
  • Embedding cursor expressions in SELECT statements

Cursor variables

  • Strong vs. weak cursor variables
  • Passing cursor variables to other programs
  • Defining REF CURSORS in packages

Developing Well-Structured and Error-Free Code

Error handling using EXCEPTIONs

  • Propagation and scope
  • "Retrying" problem transactions with EXCEPTION processing

Debugging PL/SQL blocks

  • Simplifying testing and debugging with conditional compilation
  • Interpreting compiler messages
  • Applying structured testing techniques
  • Building and applying a test bed
  • Leveraging the debugging facilities in SQL Developer

Achieving Maximum Reusability

Writing stored procedures and functions

  • Calling and invoking server-side logic
  • Passing input and output parameters
  • Implementing an autonomous transaction

Coding user-written functions

  • Calling PL/SQL functions from SQL
  • Building table-valued functions

Developing safe triggers

  • Employing :OLD and :NEW variables
  • Avoiding unreliable trigger constructs
  • Exploiting schema and database triggers

Exploiting Complex Datatypes

Collection types

  • PL/SQL tables, nested tables, VARRAYs
  • Stepping through dense and nonconsecutive collections

Bulk binding for high performance

  • Moving data into and out of PL/SQL blocks
  • BULK COLLECT INTO and FORALL
  • BULK cursor attributes
  • BULK EXCEPTION handling

Invoking Native Dynamic SQL

Finessing the compiler

  • The EXECUTE IMMEDIATE statement
  • The RETURNING INTO clause

Types of dynamic SQL

  • Building SQL statements during runtime
  • Autogenerating standard code

Package Tips and Techniques

  • Package structure: SPEC and BODY
  • Eliminating dependency problems
  • Overloading for polymorphic effects
  • Evaluating application frameworks
  • Declaring and using persistent global variables
