What is pl sql
Procedural language/structured query language is known as pl/sql. In the oracle database management system (dbms), it is a strong programming language used to develop database applications and stored procedures.
Because pl/sql is a procedural extension of sql, users may create procedural logic in addition to sql queries, including loops, conditional expressions, and subroutines. You can build sophisticated database applications with pl/sql that can work with a lot of data, do computations, and apply business logic.
Stored procedures, which are pre-compiled database programs that may be run directly in the database, are often made using pl/sql. Stored procedures are helpful for developing sophisticated business processes that include database activities since they may be invoked by other programs or scripts.
Additionally, pl/sql includes exception handling, which enables you to identify and address mistakes that may arise while a program is being executed. As a result, creating reliable and error-free database applications is made simpler.
Pl sql full form
Pl/sql stands for procedural language/structured query language.
Features of pl/sql
Procedural language/structured query language, sometimes known as pl/sql, is a programming language used by the oracle database management system (dbms) to build database applications and stored procedures.
Pl/sql has some of the following characteristics.
- Procedural language – because pl/sql is a procedural language, users may create procedural logic in addition to sql queries, such as loops, conditional statements, and subroutines.
- Close interaction with sql – because pl/sql and sql are closely interconnected, it is simple to write sophisticated sql statements and carry out data manipulation operations.
- Exception handling pl/sql – includes exception handling, allowing you to identify and address faults that may arise while a program is being executed.
- Modularity – the ability to group pl/sql programs into packages makes it simple to reuse code and maintain an extensive codebase.
- Scalability – pl/sql is extremely scalable and effective at handling huge amounts of data. Applications at the enterprise level frequently use it.
- Security – pl/sql is a safe programming language with features like roles and privileges to manage access to private information.
- Portability – if a database system supports plsql, it is simple to transfer plsql code to that system.
Pros and cons plsql
Procedural language/structured query language, sometimes known as plsql, is a programming language used by the oracle database management system (dbms) to build database applications and stored procedures.
Here are some advantages and disadvantages of using pl/sql.
Pros.
- Integration with sql – because plsql and sql are closely interwoven, it is simple to write complicated sql statements and carry out data manipulation operations.
- Speed – plsql is faster than interpreted languages like sql since it is a compiled language. It can effectively manage enormous volumes of data and is optimized for database operations.
- Scalability – plsql is extremely scalable and effective at handling massive amounts of data. Applications at the enterprise level frequently use it.
- Security – plsql is a safe programming language with features like roles and privileges to manage access to private information.
- Modularity – the ability to group plsql progrms into packages makes it simple to reuse code and maintain a sizable codebase.
Cons.
- Oracle-specific – plsql is less portable than other programming languages since it is specific to the oracle dbms.
- Learning curve – for developers who are not familiar with oracle dbms, plsql might be challenging to learn. It needs familiarity with sql and has a special syntax that can be difficult to learn.
- Maintenance – if plsql code is disorganized or contains intricate relationships between packages, it can be challenging to maintain.
- Limited features – plsql has fewer functionality than other programming languages for general-purpose programming occupations.

Oracle pl/sql
Oracle a procedural programming language called pl/sql was created especially for the oracle database management system (dbms). The term “procedural language/structured query language” (pl/sql) refers to the programming language that is used to create database objects such as stored procedures, functions, triggers, and other things that may be utilized by oracle database.
Pl/sql is based on the sql language, which is used to communicate with databases and is comparable to other procedural programming languages like c and java. Writing code that interacts with database tables, views, and other objects is simply because to the ability to easily incorporate pl/sql code in sql queries.
A few of pl/sql’s important characteristics are as follows.
- Assistance with programming elements including loops, conditional logic, and functions.
- Integration with sql for database retrieval and manipulation.
- Exception management for error recovery and identification
- Support for triggers that may be automatically invoked in response to database events.
- Support for stored procedures and functions for enhanced performance and security.
For building and administering sophisticated database applications, oracle database administrators and developers frequently employ pl/sql. The ability to generate and save pl/sql programs in a database makes them available for usage by other applications and users.
Difference between pl sql and sql
A common language for handling relational databases is called sql (structured query language). Creating, modifying, and querying databases are all done using sql. Data retrieval, insertion, updating, and deletion are all possible for users to do while interacting with databases.
The pl/sql (procedural language/structured query language) programming language was created especially for use with the oracle database management system (dbms). Loops, conditional statements, and functions are all procedural building blocks included in the pl/sql language, which is an extension of sql.
Pl/sql and sql have the following main distinctions from one another.
- Pl/sql is used to create stored procedures, functions, and triggers inside of the database, whereas sql is used to interface with databases and manipulate data.
- Because it describes what data to get, insert, update, or delete rather than how to accomplish it, sql is largely a declarative language. The procedural language pl/sql describes what to accomplish as well as how to do it.
- Pl/sql is used to implement business logic and application logic within the database, whereas sql is used to query data and manipulate database objects like tables and views.
- Pl/sql is optimized for application logic and performance, whereas sql is optimized for data retrieval and manipulation.
- Pl/sql is exclusive to the oracle database management system, whereas sql may be used with a variety of relational database management systems.
