Difference Between pl sql and sql?

Any organization’s most important component is data. The necessity to store such a large amount of data is becoming more important as data becomes more valuable. This introduces databases, and PL/SQL and SQL are two of the most widely used relational database languages. Despite the fact that they appear to be inextricably linked, they operate in very different ways. The difference between SQL and PL/SQL  is mandatory knowledge for all students and database administrators. So, let’s learn more about these relational languages and how they differ.


About SQL

SQL is a strong non-procedural database language for creating, maintaining, and retrieving relational databases (a type of database that provides and stores data that are related to each other). It was created by IBM in the 1970s and allows users to communicate with a variety of database management systems depending on their availability. SQL is more abstract than procedural (code written as a series of instructions) languages and is easier to use.

There are six types SQL commands:

  • Data Manipulation Language (DML)
  • Data Definition Language (DDL)
  • Transaction Control Language (TCL)
  • Data Control Language (DCL)
  • Data Query Language (DQL)

It is widely for programmers, with over half of them using it. SQL has the following characteristics:

  • It’s a Data Manipulation Language (DML), which means it’s a language for manipulating data.
  • Data Definition Language (DDL) is a programming language that comprises instructions for determining data.
  • It helps with database remote access and Client Service Execution.
  • It includes capabilities for security and authentication.
  • You can save all of our modifications, rolled back, and saved them using them.

About Pl SQL

PL/SQL is a procedural language that allows programmers to combine the capabilities of SQL with procedural statements. The acronym PL/SQL stands for SQL Procedural Language Extensions. All statements in PL/SQL are run at the same time, including triggers, functions, procedures, and other features that improve the functionality of an operation while reducing traffic. Its structure helps to build server pages and online applications by Oracle Corporation in the 1990s and includes features like abstraction and error handling.

A PL/SQL block has four parts: Declare, Begin, Exception, and End.

Here are some important features of PL SQL:

  • SQL and PL/SQL have a close relationship. It has all of SQL’s functionality.
  • It facilitates a thorough examination of the error.
  • PL/SQL supports a wide range of data types and structures.
  • The use of functions and procedures is beneficial to structured programming.
  • Supports for OOPs (Object Oriented Programming)
  • It’s also possible to create Server Pages and Web Apps.



Applications of SQL and PL SQL

SQL statements are a fantastic alternative for developing analytical reports because of its detail-oriented nature and the fact that it can interface directly with databases. It’s useful in supporting applications that require simple updating because it writes DML statements. It is primarily for data manipulation and is capable of doing such.

PL/SQL is an application-oriented language that largely helps to create user interfaces and back-end functionality for web pages. For these PL/SQL-based programs, SQL is responsible for providing data. For creating difficult logic, PL/SQL is compatible with Java and PHP.


PL/SQL is SQL with some procedural characteristics added to it, and it uses procedures, functions, control structures, cursors, and triggers to accomplish all of the tasks that SQL does, but on enormous amounts of data. SQL specifies all data but not how it should be obtained. This is where the PL/SQL language comes in. With the introduction of PL/SQL, we can now easily solve complicated SQL problems that were before insurmountable. Data has become the new oil in this century, and data management has never been more important. As a result, many enterprises rely on PL/SQL to run. SQL and PL/SQL skills can be extremely beneficial.
