More About

Our SQL class is designed with the beginner in mind. In the SQL portion, you’ll learn how to build applications or generate business reports, master SQL using an Oracle database, and learn PL/SQL extension language to write sophisticated queries against an Oracle database.

The Java programming portion covers most Java syntax elements, concentrating on fundamental and universally useful elements. Early in the course the concept of objects is introduced so that later concepts can be discussed from the perspective of object orientation. You will learn to write useful Java classes, apply object-oriented concepts such as inheritance, and create Java programs that work with these classes.

Oracle

Oracle Database 10g/11g

You need to have full administrative access to Oracle 10g or 11g. If you do not, you can use Oracle 11g Express Edition:

1. Download Oracle Database Express Edition for either 32 or 64 bit OS: http://www.oracle.com/technetwork/database/database-technologies/express-edition/overview/index.html?ssSourceSiteId=ocomen. Note: you will need to register for a free account to gain access to the download.

2. Execute the file you downloaded by double-clicking on the folder and then double-clicking on Setup.exe.

3. Run through the Installer accepting all the defaults. Make your password system (all lowercase). Make sure to write down and keep your password.

Note: for any IT Department personnel who are setting up a work computer for a student: (1) This class requires the use of the Oracle supplied HR demo schema, with the permissions and objects in the state in which Oracle created them. The HR schema is created by default during an install but is not always unlocked. Please unlock the schema, assigning a password. Please make sure the student has the password. (2) If you will be using a work laptop at home, then install Oracle at home. If your IT department is installing it at work, make sure they disconnect from both the internet and the intranet before launching the install. The safest way to do this is to remove the ethernet connection from your laptop and turn off your wireless connection

Oracle Client Options

1. Install Oracle SQL Developer. 1. If you are on a Windows 32 bit platform click here. Download "Windows 32-bit - zip file includes the JDK1.6.0_35".  2. For Windows 64 bit and other platforms, click here. NOTE: For Windows 64 bit platforms download "Windows 64-bit - zip file includes the JDK 7".

2. Create a folder called sqldeveloper in the Oracle folder located on c: and then extract the sqldeveloper.zip to that sqldeveloper folder you just created.

3. Within that folder, open the sqldeveloper folder.

4. Double-click sqldeveloper.exe to start SQL Developer

Class Files

1. Download the class files.

2. After downloading the class files, create a directory on your hard drive named "Webucator" that can be found easily.

3. On Windows it is recommended the new folder have a path of C:\Webucator.*

4. Extract the files to the folder you just created.

* If you are using XAMPP (e.g, for PHP classes), you must place the Webucator folder on the C:\xampp\htdocs folder.

Unlocking the HR Account

1. In SQL Developer, log in using this connection

  • Connection name: system
  • Username: system
  • Password: system (This should be the password you created when you installed Oracle)

2. Open the HR_Unlock_Account.sql file from your class files.

3. Click on the second green play button (F5) to execute the sql query.

4. To continue setup, click on the green + under the Connections tab, and add the criteria below:

  • Connection Name: hr
  • Username: hr
  • Password: hr
  • Click on Connect. A worksheet should open up on a tab that's labeled "hr".

5. Now that you're connected to HR, you're ready to test.

  • Enter the following in the worksheet: select * from regions;
  • Click on the "green arrow" to execute your code.
  • If you get back 2 columns and 4 rows then you are all set.

How do I get the Java software and files I need?

Download the Java SE Development Kit (JDK) 8, Java SE 8.0 API Documentation, and Java SE Runtime Environment (JRE) 8 Update XX here. You do not need to download the bundles that include JavaFC, Java EE, or Netbeans. You only need the JDK that includes the JRE and command-line development tools. After installation, the files will be located on the C drive, usually at C:\Program Files\Java\jdk1x.

Download your Java editors/IDEs for Windows:

Option 1: Crimson Editor is probably the best option unless you have a specific reason for using the Eclipse Integrated Development Environment (IDE) listed below.

  1. Go to http://www.crimsoneditor.com.
  2. Choose the option for Download from the left-hand navigation menu.
  3. Choose the most recent release from one of the download mirrors.
  4. Execute the file you just downloaded by double-clicking on it.
    1. Read the License Agreement and click on the button labeled I Agree.
    2. When asked what components to install, you can leave the default settings.
    3. Install Location can be left as default.
    4. When the install finishes, click the button labeled Close.

Option 2: Eclipse Integrated Development Environment (IDE), which is optional for this class at the discretion of the instructor.

  1. Go to http://www.eclipse.org/downloads.
  2. Choose the option Eclipse IDE for Java Developers. This downloads a zip file.
    1. For basic Java classes, we use Eclipse IDE for Java Developers, which does not include Java EE capabilities such as Servlets and JSPs.
    2. For Java EE classes, download Eclipse IDE for Java EE Developers.
  3. Unzip/Extract the downloaded file to C:\. The installation is a simple unzip to C:\ (Eclipse does not "install"—you run it directly from eclipse.exe, which will be in C:\eclipse after the unzip).
How do I get the Oracle software and files I need?

You need to have full administrative access to Oracle 10g or 11g. If you do not, you can download the Oracle Database Express Edition for either 32- or 64-bit OS here. You will need to register for a free account to gain access to the download.

You will also need to install Oracle SQL Developer for either Windows 32- or 64-bit platforms. Download "Windows 32-bit - zip file includes the JDK1.6.0_35" here, or download " Windows 64-bit with JDK 8 included" here.

Download the class files here. Create a directory on your hard drive named "Webucator" that can be found easily and extract the files to the folder you just created. If you are using XAMPP (e.g., for PHP classes), you must place the Webucator folder on the C:\xampp\htdocs folder.

    2. Click on the green arrow to execute your code. 
    3. If you get back 2 columns and 4 rows, then you are all set.
