sql and plsql difference
sql and plsql difference
SQL stands for Structured Query Language, which is a standard language used for managing and manipulating relational databases. SQL is used for querying, updating, and managing data within tables. PL/SQL, on the other hand, stands for Procedural Language/Structured Query Language, which is a procedural extension of SQL. PL/SQL allows users to write procedural code, such as loops and conditional statements, directly within the database. This enables developers to create more complex and powerful database applications, as they can include programming constructs in addition to standard SQL queries.

- SQL stands for Structured Query Language and is used for managing and manipulating data in relational databases. It is a standard language for querying and updating data.
- PL/SQL stands for Procedural Language/Structured Query Language and is Oracle Corporation’s proprietary extension of SQL. It adds procedural programming constructs like loops and conditional statements to SQL.
- SQL is mainly used for querying and updating data in a database, while PL/SQL is used for writing procedural code like functions and stored procedures that can be executed on the database server.
- SQL is a declarative language, which means you specify what data you want to retrieve or update without specifying how to do it. PL/SQL, on the other hand, is a procedural language where you specify the steps to be executed.
- SQL is more focused on data manipulation and retrieval, while PL/SQL allows for more complex logic and operations to be performed on the data.
- SQL queries are typically executed directly against the database, while PL/SQL code is generally stored and executed on the database server.
- SQL is a standard language that is supported by most relational database management systems, while PL/SQL is specific to Oracle databases.
In offering a training program to students, it would be beneficial to cover both SQL and PL/SQL, as they are commonly used in the industry for working with databases. It would also be important to emphasize the differences between the two languages and the advantages of using PL/SQL for writing stored procedures and functions within an Oracle database.
