最新做了一個連接Oracle的代碼，要配好環境變量：ClassPath=.;E:/j2sdk14/lib/tools.jar;E:/oracle/ora90/jdbc/lib/classes12.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.
*/// You need to import the java.sql package to use JDBC
import java.sql.*;class Test
{
public static void main (String args [])
throws SQLException
{
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
/* try{
Class.forName("oracle.jdbc.driver.OracleDriver");
}catch(Exception e){
System.out.println("No Driver!");
}
*/
// Connect to the database
// You must put a database name after the @ sign in the connection URL.
// You can use either the fully specified SQL*net syntax or a short cut
// syntax as <host>:<port>:<sid>. The example uses the short cut syntax.
String url = "jdbc:oracle:thin:@172.28.31.85:1521:YIKATONG";
String userName = "scott";
String passWord = "tiger"; if (args.length > 0) url = args[0];
if (args.length > 1) userName = args[1];
if (args.length > 2) password = args[2];
System.out.println(url);
System.out.println(userName);
System.out.println(password);
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
while (rset.next ())
System.out.println (rset.getString (1));
}
}
