What is PL SQL in Oracle Database?

Publish date: 2023-03-08
In Oracle database management, PL/SQL is a procedural language extension to Structured Query Language (SQL). The purpose of PL/SQL is to combine database language and procedural programming language. PL/SQL blocks can be compiled once and stored in executable form to improve response time.

Also to know is, what is PL SQL and what is it used for?

SQL is a structured query language used for data manipulation, whereas PL/SQL is a procedural language to design applications. PL/SQL is an application language usually used to build, format and display the user screens, web pages and reports, while SQL provides data for these applications.

The basic difference between SQL and PL/SQL is that in SQL a single query gets executed at a time whereas, in PL/SQL a whole block of code get executed at a time.

Besides, is PL SQL only for Oracle?

PL/SQL (Procedural Language for SQL) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 6 - stored PL/SQL procedures/functions/packages/triggers since version 7), Times Ten in-memory database (since version 11.2.

Where is PL SQL used?

PL/SQL is an extension of Structured Query Language (SQL) that is used in Oracle. Unlike SQL, PL/SQL allows the programmer to write code in a procedural format. Full form of PL/SQL is "Procedural Language extensions to SQL".

Is SQL a programming language?

SQL (Structured Query Language) is a database management language for relational databases. SQL itself is not a programming language, but its standard allows creating procedural extensions for it, which extend it to functionality of a mature programming language.

Which software is used for PL SQL programming?

PL/SQL is not a standalone programming language; it is a tool within the Oracle programming environment. SQL* Plus is an interactive tool that allows you to type SQL and PL/SQL statements at the command prompt.

Why do we need PL SQL?

PL/SQL is most useful to write triggers and stored procedures. Stored procedures are units of procedural code stored in a compiled form within the database. Block Structures: PL SQL consists of blocks of code, which can be nested within each other. Each block forms a unit of a task or a logical module.

Why we use bulk collect in Oracle?

Since the BULK COLLECT fetches the record in BULK, the INTO clause should always contain a collection type variable. The main advantage of using BULK COLLECT is it increases the performance by reducing the interaction between database and PL/SQL engine.

What does := mean in PL SQL?

In Oracle database management, PL/SQL is a procedural language extension to Structured Query Language (SQL). The purpose of PL/SQL is to combine database language and procedural programming language. PL/SQL blocks can be compiled once and stored in executable form to improve response time.

Is Oracle a language?

PL/SQL is a programming language like C, Java or Pascal. In the Oracle world, there is no better way to access your data from inside a program. SQL can be natively embedded in PL/SQL programs.

What is NoSQL DB?

A NoSQL (originally referring to "non SQL" or "non relational") database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases. NoSQL databases are increasingly used in big data and real-time web applications.

Is PL SQL a scripting language?

No, SQL in it's purist form is NOT a programming language. For example Microsoft created T-SQL, PL/pgSQL was created by PostgreSQL, and Oracle created PL-SQL. These all have looping and control structures but the No, SQL in it's purist form is NOT a programming language.

What is PL SQL block structure?

PL/SQL Block Structure. A block is a unit of code that provides execution and scoping boundaries for variable declarations and exception handling. PL/SQL allows you to create anonymous blocks (blocks of code that have no name) and named blocks, which may be packages, procedures, functions, triggers, or object types.

Is PL SQL still used?

The answer is that PL/SQL is not growing, but not going away either. Because it is used in the Oracle database, and the Oracle database is a fixture of enterprise systems world-wide, it will outlive you. High-performance batch processing has to happen close to the data, so PL/SQL will continue to rule in this area.

What is Oracle used for?
