JAVA連接Oracle的代碼

　　最新做了一個連接Oracle的代碼，要配好環境變量： ClassPath=.;E:j2sdk14lib ools.jar;E:oracleora90jdbclibclasses12.zip

　　測試的電腦已經裝好Oracle客戶端，而且用SQLplus可以連接上。

　　* This sample shows how to list all the names from the EMP table

　　*

　　* It uses the JDBC THIN driver. See the same program in the

　　* oci8 samples Directory to see how to use the other drivers.

　　import java.sql.*; class Test

　　// Connect to the database

　　// You must put a database name after the @ sign in the connection URL.

　　String passWord = "tiger"; if (args.length > 0) url = args[0];

　　Connection conn =

　　DriverManager.getConnection (url, userName, password); // Create a Statement

　　Statement stmt = conn.createStatement (); // Select the ENAME column from the EMP table

　　ResultSet rset = stmt.executeQuery ("select * from Test"); // Iterate through the result and print the employee names
