Oracle Database 10g: Program with PL/SQL

COURSE OVERVIEW
Oracle Database 10g: Program with PL/SQL
Duration/Training
Format /Global
Description
05 Day (40 Hrs.)
Instructor-Led Training
This class is applicable to Oracle8i, Oracle9i and Oracle
Database 10g users.
This course introduces students to PL/SQL and helps them
understand the benefits of this powerful programming language.
In the class, students learn to create PL/SQL blocks of
application code that can be shared by multiple forms, reports,
and data management applications.
Students learn to create anonymous PL/SQL blocks, stored
procedures, and functions. They learn about declaring variables
and trapping exceptions. Students will also learn to develop
stored procedures, functions, packages and database triggers.
Students will learn to manage PL/SQL program units manage
dependencies, manipulate large objects, and use some of the
Oracle-supplied packages. Students use iSQL*Plus to develop
these program units. Demonstrations and hands-on practice
reinforce the fundamental concepts.
This course counts towards the Hands-on course requirement for
the Oracle Database 10g Administrator Certification. Only
instructor-led inclass or instructor-led online formats of this
course will meet the Certification Hands-on Requirement. Self
Study CD-Rom and Knowledge Center courses are excellent
study and reference tools but DO NOT meet the Hands-on
Requirement for certification.
