Overview of Querying for Data in Oracle Database

In outline, to query Oracle Database from a Java class to retrieve data, you must do the following:

Create a connection by using the OracleDataSource.getConnection method. This is covered in Chapter 3, "Connecting to Oracle Database".

Define your SQL statements with the methods available for the connection object. The createStatement method is used to define a SQL query statement.

Using the methods available for the statement, run your queries. You use the executeQuery method to run queries on the database and produce a set of rows that match the query conditions. These results are contained in a ResultSet object.

You use a ResultSet object to display the data in the application pages.
