Oracle PL-SQL Programming

This Oracle PL/SQL training video by Uplatz provides comprehensive demonstration of Oracle PL/SQL programming concepts and their application in the industry.

 

Oracle PL/SQL is an extension of SQL language, designed for seamless processing of SQL statements enhancing the security, portability, and robustness of the database. This PL/SQL online programming course explains some important aspect of PL SQL language like block structure, data types, packages, triggers, exception handling, etc.

PL/SQL is a combination of SQL along with the procedural features of programming languages. It was developed by Oracle Corporation in the early 90's to enhance the capabilities of SQL. PL/SQL is one of three key programming languages embedded in the Oracle Database, along with SQL itself and Java. This tutorial will give you great understanding on PL/SQL to proceed with Oracle database and other advanced RDBMS concepts.

The PL/SQL programming language was developed by Oracle Corporation in the late 1980s as procedural extension language for SQL and the Oracle relational database. Following are certain notable facts about PL/SQL −

·      PL/SQL is a completely portable, high-performance transaction-processing language.

·      PL/SQL provides a built-in, interpreted and OS independent programming environment.

·      PL/SQL can also directly be called from the command-line SQL*Plus interface.

·      Direct call can also be made from external programming language calls to database.

·      PL/SQL's general syntax is based on that of ADA and Pascal programming language.

·      Apart from Oracle, PL/SQL is available in TimesTen in-memory database and IBM DB2.

 
Features and Advantages of PL/SQL

 

PL/SQL has the following advantages −

·      PL/SQL allows sending an entire block of statements to the database at one time. This reduces network traffic and provides high performance for the applications.

·      PL/SQL gives high productivity to programmers as it can query, transform, and update data in a database.

·      PL/SQL saves time on design and debugging by strong features, such as exception handling, encapsulation, data hiding, and object-oriented data types.

·      Applications written in PL/SQL are fully portable.

·      PL/SQL provides high security level.

·      PL/SQL provides access to predefined SQL packages.

·      PL/SQL provides support for Object-Oriented Programming.

·      PL/SQL provides support for developing Web Applications and Server Pages.
