以下內容來自互連網
1. MySQL( http://www.mysql.com ) mysql-connector-java-2.0.14-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 ) ;
Class.forName( "net.sourceforge.jtds.jdbc.Driver" );
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 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.access由於access並不是作為一項服務運行，所以url的方法對他不適用。access可以通過odbc，也可以通過伺服器映射路徑的形式找到.mdb檔案,參見 http://rmijdbc.objectweb.org/Access/access.html
JDBC API的使用方法
(1)登記並載入JDBC驅動程式；
兩種方法：
Class.forName(String drivername);
DriverManager.registerDriver(Driver driver) (2)建立與SQL資料庫的串連；
DriverManager的getConnection()方法：
Connection getConnection(String url):url表示資料庫地址字串；
Connection getConnection(String url,String user,String pwd)
Connection getConnection(String url,Properties info)
(3)傳送一個SQL查詢；
Connection的createStatement()方法：
Statement createStatement();
Statement可以執行SQL語句，得到SQL查詢結果。 (4)獲得結果集。
Statement的執行SQL語句方法：
ResultSet executeQuery(String sql):執行select語句
int executeUpdate(String sql)：執行更新語句，如insert,delete,update. (5)檢索查詢結果。
ResultSet的方法：
boolean next():沒有行時返回false;
String getString(String columnName)：返回列名對應的值。
