1.Access

package samz;

import java.sql.*;

public class AccessTest {

public Connection conn = null;
public Statement sta = null;
public ResultSet rs = null;

public String url="jdbc:odbc:db1";
public String userName="wang";

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 block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();

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。


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

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
