This guide will walk through the steps to install Oracle Database Express Edition 11g Release 2 and SQL Developer on Windows 10.

Downloading the database

Download it from this link. You have to create an oracle account as well. You will get a zip file. If you choose 64 bit version, we will get Unzip the file which will create the main folder DISK1, it contains the installer. Go there and execute setup.exe. Follow theses steps:

  • (1) Welcome screen. click next.

  • (2) License Agreement. If you are OK with the terms then select 'I accept ...'.

  • (3) It will choose the installation location. By default, it is "C:\oraclexe". You can change it if you want to.

  • (7) Installation ends, click on 'Finish'.

  • (8) Go to the Windows Start menu and look for 'Oracle Database 11g Express':

  • (9) The installation process above should have started the server already. Let's verify that. From above 'start menu' click on 'Run SQL Command Line' and use 'conn' command to connect the database. We are going to connect as user 'system' (enter the same password you chose during the installation process): We have successfully connected.

  • (6) Now a new tab named 'my conn' will open up which can be used to run SQL queries. Let's check the default schema by entering the following statement.
