Chapter 1: Introduction

This chapter provides a brief overview of the SQL language and what it is used for. It also sets the stage for the rest of the tutorial by introducing the key concepts and terms that will be covered.

Chapter 2: Restricting and Sorting Data

In this chapter, you'll learn how to retrieve specific data from a database using the SELECT statement. You'll also learn about the WHERE clause, which allows you to specify conditions to narrow down the results.

Chapter 3: Single Row Functions

Single row functions are used to manipulate data. In this chapter, you'll learn about the various single row functions available in SQL, including string, numeric, and date functions.

Chapter 4: Displaying Data From Multiple Tables

SQL allows you to retrieve data from multiple tables, which is useful when you need to combine data from multiple sources. In this chapter, you'll learn about the different types of join statements and how to use them to retrieve data from multiple tables.

Chapter 5: Aggregating Data using Group Functions

Group functions are used to summarize data from a database. In this chapter, you'll learn about the various group functions available in SQL, including SUM, AVG, MIN, and MAX.

Chapter 6: Sub Queries

Sub queries are used to retrieve data from one table based on data from another table. In this chapter, you'll learn about the different types of sub queries and how to use them in SQL.

Chapter 7: Manipulating Data

In this chapter, you'll learn about the different data manipulation statements available in SQL, including INSERT, UPDATE, and DELETE.

Chapter 8: Creating and Managing Tables

This chapter covers the basics of creating tables in SQL and managing them. You'll learn about the CREATE TABLE statement and how to use it to create tables, as well as how to alter existing tables.

Chapter 9: Including Constraints

This chapter covers how to create and use constraints to enforce rules and restrictions in a database. This is an essential aspect of database management and helps to ensure the accuracy and integrity of the data stored in the database.

Chapter 10: Views

This chapter discusses how to create and use views in SQL. Views provide a way to access data from a database without having to perform complex queries. They also provide a way to simplify the data and present it in a way that is easy to understand.

This chapter covers various other objects that are commonly used in SQL databases, such as sequences, synonyms, and procedures. This chapter provides a complete overview of these objects and explains how to use them to manage databases.

Chapter 12: Index

This chapter explains how to create and use indexes in SQL. Indexes are used to improve the performance of database queries by allowing the database to find the data it needs more quickly. This chapter provides a comprehensive explanation of how to create and use indexes effectively.

Chapter 13: Set Operators

This chapter discusses how to use set operators in SQL, such as union, intersection, and difference. These operators are used to combine the results of multiple queries into a single result set.
