Join tables in Oracle

Oracle JOINS are used to retrieve data from multiple tables. An Oracle JOIN is performed whenever two or more tables are joined in a SQL statement.

There are 4 different types of Oracle joins:

  • Oracle INNER JOIN (or sometimes called simple join)
  • Oracle LEFT OUTER JOIN (or sometimes called LEFT JOIN)
  • Oracle RIGHT OUTER JOIN (or sometimes called RIGHT JOIN)
  • Oracle FULL OUTER JOIN (or sometimes called FULL JOIN)

Create a user and grant permissions in Oracle

As always, begin by connecting to your server where Oracle is hosted, then connect to Oracle itself as the SYSTEM account.

The SYSTEM account is one of a handful of predefined administrative accounts generated automatically when Oracle is installed. SYSTEM is capable of most administrative tasks, but the task we’re particularly interested in is account management.

Work with database views in Oracle

You can use SQL to create a view on tables and feature classes in an enterprise geodatabase to restrict what columns or records are available to view users, or you can define a view to join information from two tables or a feature class and a table. When you include the spatial column in the view definition, view users can visualize the features in a map in an ArcGIS Desktop client.

Configure your network switch

Check the model number of your shiny new switch. Or, if you are using a spare, check the device hardware and its connected cables for any damages. If everything checks out, power on the switch and verify that all the indicator lights are in working order. Next, use a rollover cable to console into the switch from your computer. To do this, you will need to download and install Putty (or a similar, fun-named software tool). Run Putty and select the 9600 speed serial connection.
