SQL Developer: Install and Configure for Windows

SQL Developer can be used to create queries that can be used to retrieve data from the Data Warehouse. If the Software Center application is installed on the Windows computer, it can be used to install SQL Developer. The benefit of installing from Software Center is that SQL Developer is preconfigured to work with the Data Warehouse.

If Software Center is not available on the computer, SQL Developer can be manually installed and configured.

SQL Developer requires the Java Development Kit (JDK) version 8 or version 11, also known as JDK 1.8 or JDK 1.11

Verify Proper version of JDK is installed

  1. Click in the search box in the Windows task bar
  2. Start typing Command Prompt
  3. Select Command Prompt application
  4. Type java -version
  5. Press Enter
    1. If JDK is installed, the version will be displayed
      • The version will be the first line. It should be either 1.8 or 1.11
      • Note: there are various distributions of Java: OpenJDK, Oracle, Amazon Corretto, etc. They all will work with SQL Developer.

If the computer has JDK version 1.8 or 1.11, continue on to the install SQL Developer section below.
