Creating a View

Create a view that returns information about patrons and their transactions. This view queries the Patrons and Transactions tables, and returns rows that contain a patron's ID, last name, and first name, along with a transaction and the transaction type. The rows are ordered by patron ID, and by transaction type within patron IDs.

To create the patrons_trans_view view, if you are not already connected, connect to the database as the user for the schema you are using for this tutorial. Right-click the Views node in the schema hierarchy on the left side, select Create View, and enter the following information. (If a tab or field is not mentioned, do not enter anything for it.)

Schema: Specify your current schema as the schema in which to create the view.

Name: patrons_trans_view

Entire SQL Query tab

In the Entire SQL Query box, enter (or copy and paste) the following statement:

SELECT p.patron_id, p.last_name, p.first_name, 
  t.transaction_type, t.transaction_date
FROM patrons p, transactions t
WHERE p.patron_id = t.patron_id
ORDER BY p.patron_id, t.transaction_type

Then click Test Syntax, and ensure that you have not made any syntax errors. If you made any errors, correct then and click Test Syntax again.

DDL

Review the SQL statement that SQL Developer will use to create the view. If you want to make any changes, go back to the Entire SQL Query tab and make the changes there.

If you want to save the CREATE VIEW statement to a SQL script file, click Save and specify the location and file name.

When you are finished, click OK.

You have finished creating the view. To see the data returned by the view, in the Connections navigator, expand Views, select PATRONS_TRANS_VIEW, and click the Data tab.
