Java串連各種資料庫的執行個體
1.Oracle8/8i/9i資料庫(thin模式)
import java.net.URL;
import java.sql.*;
public class JavaOracle ...{
public JavaOracle() ...{
}
public static void main(String[] args)...{
try ...{
// OracleDriver exist check
try ...{
Class.forName("oracle.jdbc.driver.OracleDriver");
}
catch(java.lang.ClassNotFoundException e) ...{
System.err.print(e.getMessage());
}
// Get Connection
String url="jdbc:oracle:thin:@Server:1521:SDCDB";
Connection conn=DriverManager.getConnection(url,"test","test");
// Execute sql
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("select score from MY");
while(rs.next()) ...{
System.out.println(rs.getString(1));
}
conn.close();
}
catch(SQLException ex)
while(ex!=null)
...{
System.out.println(ex.getSQLState());
}
}
}
}
2、DB2資料庫
Class.forName("com.ibm.db2.jdbc.app.DB2Driver ").newInstance();
String url="jdbc:db2://localhost:5000/sample";
//sample為你的資料庫名
String user="admin";
String password="";
Connection conn= DriverManager.getConnection(url,user,password);
3、Sql Server7.0/2000資料庫
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb";
//mydb為資料庫
String user="sa";
String password="";
Connection conn= DriverManager.getConnection(url,user,password);
4、Sybase資料庫
Class.forName("com.sybase.jdbc.SybDriver").newInstance();
String url =" jdbc:sybase:Tds:localhost:5007/myDB";
//myDB為你的資料庫名
Properties sysProps = System.getProperties();
SysProps.put("user","userid");
SysProps.put("password","user_password");
Connection conn= DriverManager.getConnection(url, SysProps);
5、Informix資料庫
Class.forName("com.informix.jdbc.IfxDriver").newInstance();
String url = "jdbc:informix-sqli://123.45.67.89:1533/myDB:INFORMIXSERVER=myserver; user=testuser;password=testpassword";
//myDB為資料庫名
Connection conn= DriverManager.getConnection(url);
6、MySQL資料庫
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
String url ="jdbc:mysql://localhost/myDB?
user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1"
//myDB為資料庫名
Connection conn= DriverManager.getConnection(url);
7、PostgreSQL資料庫
Class.forName("org.postgresql.Driver").newInstance();
String url ="jdbc:postgresql://localhost/myDB"
//myDB為資料庫名
String user="myuser";
String password="mypassword";
Connection conn= DriverManager.getConnection(url,user,password);
