实例

1.Access

 package JDBC;import java.sql.*;public class firstTest {public Connection conn = null;public Statement sta = null;public ResultSet rs = null;public String url="jdbc:odbc:db1";public String userName="wang";public String password="123";public firstTest() {try {Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();//保证相应的Driver类已经被加载到jvm中，//并且完成了类的初始化工作} catch (InstantiationException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IllegalAccessException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (ClassNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();System.out.println("装载失败!");return;}try {conn = DriverManager.getConnection(url,userName,password);} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();System.out.println("连接成功?!");return;}try {sta = conn.createStatement();} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();System.out.println("成功?!");return;}}public void getAll(String sql) {try {rs = sta.executeQuery(sql);while(rs.next()) {System.out.print(rs.getInt(1)+"/t");System.out.print(rs.getString(2)+"/t");System.out.println(rs.getInt(3));}} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();System.out.println("error");return;}}public static void main(String[] args) {// TODO Auto-generated method stubfirstTest ft = new firstTest();ft.getAll("Select * from db1");}}

2.SqlServer 2005

 

  package JDBC;import java.sql.*;public class SQLServerFirstTest {Connection conn = null;Statement stmt = null;ResultSet rs = null;public SQLServerFirstTest() { try {Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");} catch (ClassNotFoundException e) {// TODO Auto-generated catch blockSystem.out.println("load error!");} String URL = "jdbc:sqlserver://localhost:1433;DatabaseName = myDatabase"; String USER = "sa"; String PASSWORD = "123"; try {conn = DriverManager.getConnection(URL,USER,PASSWORD);} catch (SQLException e) {// TODO Auto-generated catch blockSystem.out.println("connection error!");}if (conn == null) { System.out.println("connection == null");} try { String sql = "SELECT * FROM Class"; stmt = conn.createStatement(); ResultSet rs = stmt.executeQuery(sql); while (rs.next()) { System.out.print(rs.getInt(1)+"/t");System.out.print(rs.getString(2)+"/t");System.out.println(rs.getInt(3)); } rs.close(); stmt.close(); } catch (SQLException e) { System.out.println(e.getMessage()); } finally { if (conn != null) try { conn.close(); } catch (SQLException e) { } }}public static void main(String[] args) {// TODO Auto-generated method stubSQLServerFirstTest ft = new SQLServerFirstTest();}}其中需要对sqlserver 2005 进行一些配置修改(配置工具----》配置管理-----》SQLEXPRESS的协议--->IP地址----》TCP端口 设为1433)（可以选择其它用户名及密码，我该开始时用的是windows 身份认证，没成功，后来启动了sqlserver 身份认证，用来sa及123就好使了，其中问题多多，请自己查找资料，实际本人也不会，只是乱弄罢了O(∩_∩)O哈哈~）

1. MySQL(

JDBC API的使用方法
(1)登记并加载JDBC驱动程序；
两种方法：
Class.forName(String drivername);
DriverManager.registerDriver(Driver driver)
(2)建立与SQL数据库的连接；
DriverManager的getConnection()方法：
Connection getConnection(String url):url表示数据库地址字符串；
Connection getConnection(String url,String user,String pwd)
Connection getConnection(String url,Properties info)
(3)传送一个SQL查询；
Connection的createStatement()方法：
Statement createStatement();
Statement可以执行SQL语句，得到SQL查询结果。
(4)获得结果集。
Statement的执行SQL语句方法：
ResultSet executeQuery(String sql):执行select语句
int executeUpdate(String sql)：执行更新语句，如insert,delete,update.
(5)检索查询结果。
ResultSet的方法：
boolean next():没有行时返回false;
String getString(String columnName)：返回列名对应的值。

各种数据库的JDBC驱动下载及连接字符串URL写法 2007-07-02 19:28 和田雨
为了方便大家查找，整理内容如下：
1. MySQL(
Class.forName( "org.gjt.mm.mysql.Driver" );     //这是老版本的字符串现为 com.mysql.jdbc.Driver
cn = DriverManager.getConnection( "jdbc:mysql://MyDbComputerNameOrIP:3306/myDatabaseName", sUsr, sPwd );

 

 

2. PostgreSQL(
Class.forName( "org.postgresql.Driver" );
cn = DriverManager.getConnection( "jdbc:postgresql://MyDbComputerNameOrIP/myDatabaseName", sUsr, sPwd );

 

3. Oracle(
Class.forName( "oracle.jdbc.driver.OracleDriver" );
cn = DriverManager.getConnection( "jdbc:oracle:thin:@MyDbComputerNameOrIP:1521:ORCL", sUsr, sPwd );

 

4. Sybase
Class.forName( "com.sybase.jdbc2.jdbc.SybDriver" );
cn = DriverManager.getConnection( "jdbc:sybase:Tds:MyDbComputerNameOrIP:2638", sUsr, sPwd );
//(Default-Username/Password: "dba"/"sql")

 

5. Microsoft SQLServer()
Class.forName( "net.sourceforge.jtds.jdbc.Driver" );
cn = DriverManager.getConnection( "jdbc:jtds:sqlserver://MyDbComputerNameOrIP:1433/master", sUsr, sPwd );

 

6. Microsoft SQLServer()
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" );
cn = DriverManager.getConnection( "jdbc:microsoft:sqlserver://MyDbComputerNameOrIP:1433;databaseName=master", sUsr, sPwd );

 

7. ODBC  （access）
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );
Connection cn = DriverManager.getConnection( "jdbc:odbc:" + sDsn, sUsr, sPwd );

 

8.DB2(新添加)
Class.forName("com.ibm.db2.jdbc.net.DB2Driver");
String url="jdbc:db2://192.9.200.108:6789/SAMPLE"
cn = DriverManager.getConnection( url, sUsr, sPwd );

 

9.Microsoft SQL Server series (6.5, 7.x and 2000) and Sybase 10

JDBC Name: jTDS
URL:

语法:
Class.forName("net.sourceforge.jtds.jdbc.Driver ");
Connection con = DriverManager.getConnection("jdbc:jtds:sqlserver://host:port/database","user","password");
or
Connection con = DriverManager.getConnection("jdbc:jtds:sybase://host:port/database","user","password");

 

10.Postgresql
JDBC Name: PostgreSQL JDBC
URL:
语法:
Class.forName("org.postgresql.Driver");
Connection con=DriverManager.getConnection("jdbc:postgresql://host:port/database","user","password");

 

11.IBM AS400主机在用的JDBC语法
有装V4R4以上版本的Client Access Express
可以在C:/Program Files/IBM/Client Access/jt400/lib
找到 driver 档案 jt400.zip，并更改扩展名成为 jt400.jar
语法:
java.sql.DriverManager.registerDriver (new com.ibm.as400.access.AS400JDBCDriver ());
Class.forName("com.ibm.as400.access.AS400JDBCConnection");
con = DriverManager.getConnection("jdbc:as400://IP","user","password");

 

12.informix
Class.forName("com.informix.jdbc.IfxDriver").newInstance();
String url =
"jdbc:informix-sqli://123.45.67.89:1533/testDB:INFORMIXSERVER=myserver;
user=testuser;password=testpassword";
Lib：jdbcdrv.zip<br><br>Class.forName( "com.sybase.jdbc.SybDriver" )
url="jdbc:sybase:Tds:127.0.0.1:2638/asademo";
SybConnection connection= (SybConnection)DriverManager.getConnection(url,"dba","sql");

 

13.SAP DB
Class.forName ("com.sap.dbtech.jdbc.DriverSapDB");
java.sql.Connection connection = java.sql.DriverManager.getConnection ( "jdbc:sapdb://" + host + "/" + database_name,user_name, password)

 

14.InterBase
String url = "jdbc:interbase://localhost/e:/testbed/database/employee.gdb";
Class.forName("interbase.interclient.Driver");
//Driver d = new interbase.interclient.Driver (); /* this will also work if you do not want the line above */
Connection conn = DriverManager.getConnection( url, "sysdba", "masterkey" );

 

15.HSqlDB
url:
driver: org.hsqldb.jdbcDriver
连接方式有4种，分别为：
con-str（内存）: jdbc:hsqldb.
con-str（本地）: jdbc:hsqldb:/path/to/the/db/dir
con-str（http）: jdbc:hsqldb:http://dbsrv
con-str（hsql）: jdbc:hsqldb:hsql://dbsrv
