Oracle PL/SQL Tutorial
SQL, as we know, is a powerful structured query language for querying, updating and retrieving data in relational databases. Looking at the intensity of data growing each data and the complexity of managing that data, Oracle created an extension to this query language in the early 90’s as Procedural Language to SQL.
This enhanced the capabilities of SQL as PL/SQL allows mixing of SQL statements with procedural constructs. Unlike SQL, PL/SQL is a programming language extending SQL, which includes procedural elements like loops, data types, control structures and others. You can create program blocks, functions, methods, triggers and packages with this extension. In simple terms, while SQL tells the relational database what to do, PL/SQL tells them how to do.
Some important features of Oracle Pl/SQL are:
- The syntax is based on ADA and Pascal programming language
- sending the block statements at once reduce network traffic and increase performance
- Features like exception handling, encapsulation, data hiding, etc., save time in debugging and designing.
In order to become a successful DBA, one should clearly know the difference between SQL and PL/SQL:
|Structured Query Language||Programming language|
|Used to write single query||Used to write complete programs|
|Source of data for preparing reports||Language for writing applications|
|Can be embedded within Pl/SQL codes||Cannot be embedded within SQL codes|
Our Oracle PL/SQL tutorial teaches various PL/SQL programming fundamentals and makes you familiar with data types, control structures, collections and records. A comprehensive study of procedural language basics- this learning package is a realistic implementation of Pl/SQL operations, subprograms, and packages. You can learn to query data using implicit and explicit cursor for loops. The tutorial also covers Exception handling in relational databases to handle PL/SQL errors.
Further, deeper insights into PL/SQL object types and language elements are also provided with suitable examples and real-world implementations. Overall, the tutorial is designed to satiate the learning needs of all types of audiences, whether beginners, intermediate or advanced-level professionals. For advanced programmers and database administrators, our tutelage will serve as a conceptual revival and can be referred time and again to revise and polish up their PL/SQL concepts.
