jdbc开发过程中,通用的步骤：首先加载驱动程序；然后获得数据库的连接。然而各种数据库的加载驱动和获得数据库语法都各不相同，而且记忆难度强。因此，有必要将各种数据库驱动程序和连接数据库固定句式进行总结，方便日后开发使用。

Db Name: Microsoft SQL Server (6.5, 7, 2000 and 2005) and Sybase (10, 11, 12).
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
由于微软的SQL Server2000的JDBC驱动不支持“反复查询”，所以，可能会出现ResultSet can not re-read row data for column x的错误。
如果使用sourceforge的jTDS驱动，就不会有上述问题了。
要使用jTDS驱动，配置要做一些变动：
JDBC Name: jTDS
Home Page: http://jtds.sourceforge.net/
JDBC Ver: 1.0.2
Download: http://sourceforge.net/project/showfiles.php?group_id=33291
Conn Code:
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");
Db Name:
Microsoft SQL Server 2000
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
JDBC Name: SQL Server 2000 Driver for JDBC
Home Page: http://www.microsoft.com/china/sql/
JDBC Ver: (SQL Server 2000 Driver for JDBC)
Download: http://www.microsoft.com/china/sql/downloads/2000/jdbc.asp
Conn Code:
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Connection conn = DriverManager.getConnection ("jdbc:microsoft:sqlserver://server1:1433","user","password");
Db Name: Oracle
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
JDBC Name: Connector/J
Home Page: http://www.oracle.com/technology/software/tech/java/
JDBC Ver: (based on Oracle)
Download: http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/
Conn Code:
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@host:port:databse","user","password");
Db Name:
MySQL
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
JDBC Name: Connector/J
Home Page: http://dev.mysql.com/
JDBC Ver: 3.1
Download: http://dev.mysql.com/downloads/
Conn Code:
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://host:port/database","user","password");
jdbc:mysql://127.0.0.1:3306/restaurant?useunicode=true&characterEncoding=utf-8
jdbc:mysql://localhost:3306/我数据库名?useUnicode=true&characterEncoding=utf-8&useSSL=false"
//useSSL=false:就是使用JDBC跟你的数据库连接的时候，你的JDBC版本与MySQL版本不兼容，MySQL的版本更高一些，在连接语句后加上“useSSL=‘true’” ，就可以连接到数据库了。更高版本
Db Name:
Sybase
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
JDBC Name: jConnect
Home Page: http://www.sybase.com.cn/cn/content/SDN/
JDBC Ver: 4.5/5.5
Download: http://www.sybase.com/detail_list?id=13&morenavId=8668&multi=true&SR=Y&show=1265
Conn Code:
Class.forName("com.sybase.jdbc2.jdbc.SybDriver").newInstance();
DriverManager.getConnection("jdbc:sybase:Tds:IP:2638?ServiceName="+database,"user","password");
Db Name:
Postgresql
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
JDBC Name: PostgreSQL JDBC
Home Page: http://jdbc.postgresql.org/
JDBC Ver: 8.0 Build 310
Download: http://jdbc.postgresql.org/download.html
Conn Code:
Class.forName("org.postgresql.Driver");
Connection con = DriverManager.getConnection("jdbc:postgresql://host:port/database","user","password");
Db Name:
IBM Informix
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
JDBC Name: Informix JDBC Driver (IBM Informix JDBC V3.0)
Home Page: http://www-306.ibm.com/software/data/informix/
JDBC Ver: 3.0.JC1

Conn Code:
Class.forName("com.informix.jdbc.IfxDriver").newInstance();
Connection conn= DriverManager.getConnection("jdbc:informix-sqli://123.45.67.89:1533/myDB:INFORMIXSERVER=myserver;user=testuser;password=testpassword";);

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
Conn Code:
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");
Db Name: Ms Access or Ms Foxpro
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Conn Code:
step 1: 配置 odbc (例如：myDb)
step 2:
String dbURL = "jdbc:odbc:myDb";
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection(dbURL);
or
String dbURL = "jdbc:odbc:driver={MicrosoftAccessDriver(*.mdb)};DBQ=dabaseName.mdb";
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection(dbURL);
