Introduction to Oracle

In this lesson, you'll jump right in and create the actual database that you'll use in all the lessons that follow. You'll learn about the most common object in Oracle: the table. Afterwards, you'll learn the common datatypes that describe the kind of information a column in a table will store.

In this lesson, you'll learn about database users and have an opportunity to create a user of your very own. This lesson will not only provide you with a crash course in SQL*Plus, but it will also help you create all the tables you'll need for your database. The lesson will discuss managing tables and how to modify their structure by altering and deleting information.

In this lesson, you'll put together all the pieces of the database puzzle. The lesson will discuss defining and managing table constraints and teach you about the five integrity constraints that Oracle supports, as well as what their purposes are. It'll show you how to define integrity constraints during table creation with the CREATE TABLE statement and after a table have been created with the ALTER TABLE statement. With this information, you'll create the primary and foreign keys for your database's tables.

You'll gain considerably more knowledge about the Structured Query Language in this lesson, where you'll be introduced to two new commands—the INSERT and SELECT commands. Then, you'll execute the commands to insert rows of data into the tables and query the data you inserted.

In this lesson, you'll learn about a useful tool called SQL*Plus and its uses. After that, you'll learn how to correct errors and manipulate lines in the SQL buffer. Finally, you'll explore some of the additional syntax that can be added to a SELECT statement.

In this lesson, you're going to learn more about the SELECT command, the most commonly used SQL statement. The SELECT command allows you to query the data in a database. You'll find that you need to be familiar with the data in your database, and that queries provide you with the means to view what's stored in your tables.

In this lesson, you'll go beyond the INSERT command's basics. You'll be introduced to more advanced features of the INSERT command, then you'll learn the different methods of inserting rows of data and apply those skills to load data into your tables. You'll also learn some troubleshooting techniques to perform when Oracle returns an error message during an INSERT command.

In this lesson, you're going to learn how to modify data in the database's tables using the UPDATE command. You'll learn how to manipulate the data in your tables by updating the values in the columns and by deleting rows of data. You'll learn how to make those changes permanent with the COMMIT command, as well as how to undo a change with the ROLLBACK command.

Up to this point in the course, you've been creating queries based on a single table. In this lesson, you'll learn how to display data from multiple tables. You'll learn how to utilize your working knowledge of the SELECT statement and explore the world of joins.

In this lesson, you'll learn more about common database objects and their uses. At this point, you'll have gained considerable knowledge of the most common database object—the table. You'll also learn about other database objects and learn how to put them to use, too. Finally, you'll make use of the data dictionary and query some useful views.

In the final lesson, you'll learn how to format query results to generate a finished report. You'll use SQL*Plus to create reports by using SELECT statements, then modify the display of the query results to create a polished report.
