Course Description:

'' this course introduces students to pl/sql and helps them understand the benefits of this powerful programming language. students learn topl/sql blocks of application code that can be shared by multiple forms, reports, and data management applications. students learn toanonymous pl/sql blocks as well as stored procedures and functions.

students learn to develop, execute, and manage pl\sql stored program units such as procedures, functions, packages, and database triggers. students also learn to manage pl/sql subprograms, triggers, declaring identifiers and trapping exceptions. students are introduced to the utilization of some of the oracle-supplied packages.

students use oracle sql developer to develop these program units. sql*plus and jdeveloper are introduced as optional tools.

learn to:

conditionally control code flow (loops, control structures)
design and use pl/sql packages to group and contain related constructs.
create triggers to solve business challenges.
use some of the oracle supplied pl/sql packages to generate screen output and file output.
create anonymous pl/sql blocks of code.
declare pl/sql variables
audience:

application developers
database administrators
developer
forms developer
pl/sql developer
portal developer
system analysts
technical consultant
