or

Connection con = DriverManager.getConnection("jdbc:jtds:sybase://host:port/database","user","password");

10.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");

11.IBM AS400主机在用的JDBC语法

有装V4R4以上版本的Client Access Express

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();

"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)

//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:     http://hsqldb.sourceforge.net/driver: org.hsqldb.jdbcDriver
