    I had long toyed with the idea of refreshing my programming skills and “upgrading” my skill set- Potenza online SQL/PLSQL training worked wonders and got me going in a very short time. I was able to cover the old ground very quickly. Adapted the approach and delivery to suit my learning style, and we have now got into new territory for me.

Frequently Asked Questions.

Is PL-SQL and SQL same?

No, PL-SQL and SQL are not the same. SQL is a standardized language for querying databases, while PL-SQL is an extension that adds programming features like loops and variables to SQL within the Oracle database environment.

What is the relationship between SQL and PL-SQL?


  • SQL: A universal query language for relational databases. It allows you to interact with data using standardized commands for tasks like retrieval, insertion, updates, and deletion.
  • PL-SQL: An extension for SQL specifically within the Oracle database environment. It adds procedural programming capabilities like loops, conditional statements (if/else), functions, variables, and exception handling on top of core SQL functionality.
  • Think of SQL as a general toolset for working with relational databases, and PL-SQL as an extension kit that adds extra functionalities specific to the Oracle database.

What is the full form of PL-SQL?

The full form of PL-SQL is Procedural Language extensions to the Structured Query Language.

What is the difference between PL-SQL and T-SQL?


  1. Focus: Both are extensions to SQL for specific database environments, but for different products.
    1. PL-SQL
    2. T-SQL (Transact-SQL)
  2. Functionality: Both offer procedural programming capabilities on top of core SQL, but with slight variations.
    1. PL-SQL
    2. T-SQL
  3. Availability: PL-SQL is specific to the Oracle database, while T-SQL is used within the Microsoft SQL Server environment.

Is PL-SQL a language?

PL-SQL straddles the line. It has its own syntax and can build complex programs, but it's designed specifically for the Oracle database. Think of it as a powerful extension to SQL that lets you write programs within the Oracle environment.

How to write PL-SQL code?

Here's a basic roadmap for writing PL-SQL code:

  • Understand SQL
  • Learn PL-SQL syntax 
  • Develop logic 
  • Use an IDE 
  • Test and refine

Is PL-SQL good for a career?

Yes, PL-SQL skills can be a valuable career asset. The demand for Oracle developers is high, and expertise in PL-SQL positions you for well-paying jobs. With strong skills, you can work on interesting database-driven projects and enjoy stability within the Oracle ecosystem.

Who invented PL-SQL?

While there isn't a single inventor credited for PL-SQL, its development is closely associated with Peter Clare. He played a pivotal role in shaping the language during his time at Oracle Corporation.

Which is faster SQL OR PL-SQL?

Generally, SQL is faster than PL-SQL for simple tasks.

How to run PL-SQL?

Here are a few ways to run PL-SQL code:

  • SQL*Plus
