Course Description

Oracle SQL (Structured Query Language) is a database query language used to manage, retrieve, and manipulate data in an Oracle Database. It utilizes standard SQL commands (SELECT, INSERT, UPDATE, DELETE) but is optimized to work specifically with Oracle's database features and tools.

Key Uses of Oracle SQL:

• Data Retrieval

• Data Manipulation

• Data Integrity

Oracle SQL is primarily used by Database Administrators (DBAs), SQL Developers, and Data Analysts to efficiently manage and work with large volumes of data.

Course Content Breakdown:

---

1. Introduction to Databases & SQL

• Understanding Databases:

  • What is a database?

  • Types of databases: Relational vs Non-relational.

  • Introduction to Oracle Database and its architecture.

• What is SQL?:

  • Definition and role of SQL in database management.

  • SQL standards and basic commands: DDL, DML, DCL, TCL.

• Oracle SQL Environment Setup:

  • Installing Oracle Database or using Oracle Cloud.

  • Introduction to Oracle SQL Developer.

  • Connecting to an Oracle Database.
    

2. Basic SQL Queries & Data Retrieval

• SELECT Statement:

  • Writing your first SELECT statement.

  • Retrieving data from a single table.

  • Using DISTINCT to remove duplicates.

• Filtering Data:

  • The WHERE clause for data filtering.

  • Comparison operators: =, !=, >, <, >=, <=.

  • Logical operators: AND, OR, NOT.

  • Pattern matching using LIKE.

  • Range checking with BETWEEN.

• Sorting Data:

  • Using the ORDER BY clause.

  • Sorting results in ascending and descending order.

• Limiting Data:

  • Fetching a specific number of rows using ROWNUM or FETCH FIRST (depending on Oracle version).
    

3. Working with Multiple Tables

• Joins:

  • Introduction to Inner Join, Left Join, Right Join, and Full Outer Join.

  • Joining multiple tables using JOIN syntax.

• Self-joins:

  • What is a self-join?

  • Example of a self-join to combine rows from the same table.

• Union and Union All:

  • Difference between UNION and UNION ALL.

  • Combining results from multiple SELECT statements.
    

4. Grouping & Aggregating Data

• Aggregate Functions:

  • Using COUNT(), SUM(), AVG(), MIN(), and MAX() for data analysis.

  • Understanding GROUP BY and HAVING clauses.

• Grouping Data:

  • Using GROUP BY to aggregate data into meaningful groups.

  • Filtering groups using HAVING.
    

5. Subqueries

• Introduction to Subqueries:

  • What are subqueries?

  • Single-row vs Multi-row subqueries.

• Using Subqueries in SELECT, WHERE, and FROM clauses:

  • Using a subquery for filtering data (e.g., in the WHERE clause).

  • Correlated subqueries: when a subquery refers to the outer query.
    

6. Data Modification & Transactions

• Data Manipulation:

  • Inserting data into tables using the INSERT statement.

  • Updating existing data using the UPDATE statement.

  • Deleting records with the DELETE statement.

• Transaction Control:

  • COMMIT and ROLLBACK: Ensuring data integrity.

  • SAVEPOINT: Creating points to rollback transactions.

  • SET TRANSACTION: Configuring transaction properties.
    

7. Managing Database Schema

• Creating Tables:

  • Basic syntax for creating tables.

  • Data types in Oracle (e.g., VARCHAR2, NUMBER, DATE).

• Altering Tables:

  • Adding, dropping, or modifying columns using ALTER TABLE.

• Dropping Tables:

  • How to remove tables using the DROP TABLE statement.
    

8. Constraints & Indexing

• Database Constraints:

  • What are constraints?

  • Types of constraints: PRIMARY KEY, FOREIGN KEY, UNIQUE, NOT NULL, CHECK.

• Creating and Managing Indexes:

  • What are indexes and why are they important?

  • Creating, dropping, and managing indexes in Oracle.
    

9. Views & Synonyms

• Creating and Using Views:

  • What is a view?

  • Creating a view with the CREATE VIEW statement.

  • Benefits of views: Data abstraction and security.

• Using Synonyms:

  • What are synonyms in Oracle?

  • Creating and using synonyms to simplify object references.
    

10. Advanced SQL Features

• Functions:

  • Built-in Functions: String, number, date, and conversion functions (e.g., TO_DATE, TO_CHAR, ROUND, SUBSTR, etc.).

  • User-Defined Functions: How to create and use custom functions.

• Triggers:

  • What are triggers and how to use them in Oracle?

  • Creating triggers to automate actions in the database.

• Stored Procedures and Packages:

  • Introduction to stored procedures and their usage.

  • Creating and managing procedures and packages for reusability.
    

11. Performance Tuning & Optimization

• Query Optimization:

  • Introduction to query performance issues.

  • Using EXPLAIN PLAN to analyze and optimize queries.

  • Optimizing joins and subqueries.

• **Using Indexes for performance improvement.

• Database Hints: Using hints to guide the optimizer.
  

12. Security & User Management

• User Management:

  • Creating and managing users in Oracle.

  • Assigning roles and privileges.

• Security:

  • Introduction to GRANT, REVOKE, and DENY statements for controlling access.

  • Understanding Oracle security models and implementing best practices.
    

13. Backup and Recovery

• Backup Strategies:

  • Overview of Oracle backup strategies.

  • Full vs Incremental backups.

• Recovery:

  • How to recover from database failures.

  • Introduction to Oracle Recovery Manager (RMAN).
