? try{

????????? String name="oracle.jdbc.driver.OracleDriver";

????????? String url="jdbc:oracle:thin@localhost:1521:database";

4. JDBC 連接 DB2- -??????????????????????????????????????

?

?

DB2 自己帶 jdbc 驅動，具體位置在 C:\Program Files\IBM\SQLLIB\java\db2jcc.jar

C:\Program Files\IBM\SQLLIB\java\db2jcc_license_cu.jar

C:\Program Files\IBM\SQLLIB\java\db2jcc_license_cisuz.jar

?

設置 CLASSPATH=.;C:\ProgramFiles\IBM\SQLLIB\java\db2jcc.jar;

C:\ProgramFiles\IBM\SQLLIB\java\db2jcc_license_cu.jar;

C:\ProgramFiles\IBM\SQLLIB\java\db2jcc_license_cisuz.jar

?

注意：在使用 jdbc 連接 db2 時，一定要用 ibm 自己的 jdk ，

否則執行會出現錯誤，可能是 ibm 的 jdbc 驅動和 sun 的 jdk 不兼容的問題

????? 具體位置在 C:\Program Files\IBM\SQLLIB\java\jdk

?

例子：

import java.sql.*;

public class ConDB2{

?Connection con;

?Statement st;

?ResultSet rs;?

?public ConDB2(){?

? try{

????????? String name="com.ibm.db2.jcc.DB2Driver";

????????? String url="jdbc:db2://localhost:50000/database";

???????? Class.forName(name);

????????? con=DriverManager.getConnection(url,"user","password");

????????? System.out.println(" 連接成功 !");

????????? con.close();??????????

? }catch(Exception e){

?? e.printStackTrace();

? }

?}

?

?public static void main(String args[]){???
