常用数据库JDBC连接写法

1. MySQL(
Class.forName( "org.gjt.mm.mysql.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
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );
Connection cn = DriverManager.getConnection( "jdbc:odbc:" + sDsn, sUsr, sPwd );

8.DB2(http://www.microsoft.com)http://jtds.sourceforge.net)http://jtds.sourceforge.net)jconn2.jarhttp://www.oracle.com/ip/deploy/database/oracle9i/)classes12.ziphttp://www.de.postgresql.org)pgjdbc2.jarhttp://www.mysql.com)mm.mysql-2.0.2-bin.jar 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:
Version: 0.5.1
Download URL:

http://sourceforge.net/project/showfiles.php?group_id=33291http://jtds.sourceforge.net/ 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:
Version: 7.3.3 build 110
Download URL:

http://jdbc.postgresql.org/download.htmlhttp://jdbc.postgresql.org/ 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

Class.forName( "com.sybase.jdbc.SybDriver" )
url="jdbc:sybase:Tds:127.0.0.1:2638/asademo";
SybConnection connection= (SybConnection)DriverManager.getConnection(url,"dba","sql");



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:    
driver:  org.hsqldb.jdbcDriver

http://hsqldb.sourceforge.net/ 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:
con-strhttp://dbsrv （ hsql ） : jdbc:hsqldb:hsql://dbsrv
