Course Description
This course introduces students to PL/SQL and helps them understand
the benefits of this powerful programming language. Participants learn
to create PL/SQL blocks of application code that can be shared by
multiple forms, reports, and data management applications. Participants
learn to create anonymous PL/SQL blocks as well as stored procedures and
functions. Participants learn to develop, execute, and manage PL\SQL
stored program units such as procedures, functions, packages, and
database triggers. Participants also learn to manage PL/SQL subprograms,
triggers, declaring identifiers and trapping exceptions. Participants
are introduced to the utilization of some of the Oracle-supplied
packages.
This course is a combination of Oracle Database PL/SQL
Fundamentals and Oracle Database Develop PL/SQL Program Units courses.
Participants use Oracle SQL Developer to develop these program units.
This
Oracle PL/SQL tutorial teaches you the basics of database programming
in PL/SQL with appropriate PL/SQL tutorials with coding examples.
PLSQL stands for "Procedural Language extensions to SQL",
and is an extension of SQL that is used in Oracle. PLSQL is closely
integrated into the SQL language, yet it adds programming constructs
that are not native to SQL.
PL/SQL is an imperative
3GL that was designed specifically for the seamless processing of SQL
commands. It provides specific syntax for this purpose and supports
exactly the same datatypes as SQL. Server-side PL/SQL is stored and
compiled in Oracle Database and runs within the Oracle executable. It
automatically inherits the robustness, security, and portability of
Oracle Database.
PL/SQL works analogously to the
embedded procedural languages associated with other relational
databases. For example, Sybase ASE and Microsoft SQL Serverhave
Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an
extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to theISO SQL's SQL/PSM standard.
PL/SQL
includes procedural language elements such as conditions and loops. It
allows declaration of constants and variables, procedures and functions,
types and variables of those types, and triggers. It can handle
exceptions (runtime errors). Arrays are supported involving the use of
PL/SQL collections. Implementations from version 8 of Oracle Database
onwards have included features associated with object-orientation. One
can create PL/SQL units such as procedures, functions, packages, types,
and triggers, which are stored in the database for reuse by applications
that use any of the Oracle Database programmatic interfaces.
