1、Oracle8/8i/9i数据库（thin模式）

//还有下面一些，内含有驱动包下载地址
1. MySQL(http://www.mysql.com)mm.mysql-2.0.2-bin.jar
Class.forName( "org.gjt.mm.mysql.Driver" );
cn = DriverManager.getConnection( "jdbc:mysql://MyDbComputerNameOrIP:3306/myDatabaseName", sUsr, sPwd );

2. PostgreSQL(http://www.de.postgresql.org)pgjdbc2.jar
Class.forName( "org.postgresql.Driver" );
cn = DriverManager.getConnection( "jdbc:postgresql://MyDbComputerNameOrIP/myDatabaseName", sUsr, sPwd );

3. Oracle(http://www.oracle.com/ip/deploy/database/oracle9i/)classes12.zip
Class.forName( "oracle.jdbc.driver.OracleDriver" );
cn = DriverManager.getConnection( "jdbc:oracle:thin:@MyDbComputerNameOrIP:1521:ORCL", sUsr, sPwd );

4. Sybase(http://jtds.sourceforge.net)jconn2.jar
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(http://jtds.sourceforge.net)

cn = DriverManager.getConnection( "jdbc:jtds:sqlserver://MyDbComputerNameOrIP:1433/master", sUsr, sPwd );

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

7. ODBC
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 );

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

JDBC Name: jTDS
URL: http://jtds.sourceforge.net/
Version: 0.5.1
Download URL: http://sourceforge.net/project/showfiles.php?group_id=33291

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");
Postgresql

JDBC Name: PostgreSQL JDBC
URL: http://jdbc.postgresql.org/
Version: 7.3.3 build 110
Download URL: http://jdbc.postgresql.org/download.html

语法:

Class.forName("org.postgresql.Driver"); 
Connection con=DriverManager.getConnection("jdbc:postgresql://host:port/database","user","password");


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");

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" )<br>url="jdbc:sybase:Tds:127.0.0.1:2638/asademo";<br>SybConnection connection= (SybConnection)DriverManager.getConnection(url,"dba","sql");<br>


补充两个
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)

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" );



我也来补一个吧：HSqlDB

url:     http://hsqldb.sourceforge.net/
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
