Oracle SQL

Harness the Power of Data with Advanced SQL Techniques

Oracle SQL is a specialised version of SQL used to interact with Oracle databases, enabling users to retrieve, manipulate, and manage data efficiently. With advanced features such as complex queries, joins, and transactional control, Oracle SQL is a crucial tool for data management in enterprise applications.

Why is Oracle SQL Important?

A

Industry Standard

SQL is the universal language for relational databases, and Oracle SQL is widely adopted by businesses for managing large datasets and supporting mission-critical applications.

A

Data Retrieval & Manipulation

Course Modules

SQL Query Execution

Learn how Oracle SQL executes queries to retrieve and modify data.

i

Data Manipulation

Use commands like SELECT, INSERT, UPDATE, and DELETE to manipulate database records.

Data Definition

Understand how to create and modify database structures using DDL commands (CREATE, ALTER, DROP).

Joins & Aggregations

Combine data from multiple tables and calculate summary statistics using JOINs and aggregate functions (SUM, AVG, COUNT).

Subqueries

Use subqueries for filtering, transforming, and structuring complex data retrieval.

PL/SQL

Extend Oracle SQL with PL/SQL for procedural operations, stored procedures, and advanced scripting.

How Oracle SQL Works

Data Management

Query Execution

SQL queries are parsed, optimized, and executed by the Oracle database engine to retrieve or modify data.
Data Management

Data Manipulation (DML)

Perform tasks like data retrieval (SELECT), data insertion (INSERT), updates (UPDATE), and deletions (DELETE).
Data Management

Data Definition (DDL)

Create and modify database structures with commands such as CREATE and ALTER.
Data Management

Join Operations

Oracle SQL supports various join types (INNER JOIN, LEFT JOIN, RIGHT JOIN) to combine data across multiple tables.
Data Management

Aggregations

Use aggregate functions to summarize data across groups of rows.
Data Management

Subqueries

Nest queries within other queries for advanced filtering and data transformation.
Data Management

PL/SQL

Integrate procedural logic with SQL to create advanced database solutions.
