常用数据库JDBC连接写法
1.MySQL(http://www.mysql.com)mm.mysql-2.0.2-bin.jar

Class.forName("org.gjt.mm.mysql.Driver");

conn=DriverManager.getConnection("jdbc:mysql://MyDbComputerNameOrIP:3306/myDatabaseName",sUsr,sPwd);

2.PostgreSQL(http://www.de.postgresql.org)pgjdbc2.jar

Class.forName("org.postgresql.Driver");

conn=DriverManager.getConnection("jdbc:postgresql://MyDbComputerNameOrIP/myDatabaseName",sUsr,sPwd);

3.Oracle(http://www.oracle.com/ip/deploy/database/oracle9i/)classes12.zip;10.2版本建议使用ojdbc4.jar

Class.forName("oracle.jdbc.driver.OracleDriver");

Connection conn=DriverManager.getConnection("jdbc:oracle:thin:@MyDbComputerNameOrIP:1521:ORCL",sUsr,sPwd);
Statement stm=conn.createStatement();
ResultSet rst=stm.executeQuery("select* from student");或者stm.executeUpdate(sql语句);
或者：
PreparedStatement pstDelete=conn.preparedStatement("Delete From student where id>=?");
PreparedStatement pstInsert=conn.preparedStatement("Insert into student values(?,?,?)");
PreparedStatement pstSelect=conn.preparedStatement("select *from student where id>=?");
int pstSelect.setString(1,Integer.toString(id));
pstInsert.setString(1,Integer.toString(id));
pstInsert.setString(2,"zhaolei");
pstInsert.setDate(3,new Date(78,2,id));
pstDelete.setString(1,Integer.toString(id));
pstDelete.executeUpdate();
pstInsert.executeUpdate();
ResultSet rs=pstSelect.excuteQuery();
4.Sybase(http://jtds.sourceforge.net)jconn2.jar

Class.forName("com.sybase.jdbc2.jdbc.SybDriver");

conn=DriverManager.getConnection("jdbc:sybase:Tds:MyDbComputerNameOrIP:2638",sUsr,sPwd);

//(Default-Username/Password:"dba"/"sql")

5.MicrosoftSQLServer(http://jtds.sourceforge.net)

Class.forName("net.sourceforge.jtds.jdbc.Driver");

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

6.MicrosoftSQLServer(http://www.microsoft.com)

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");

conn=DriverManager.getConnection ("jdbc:microsoft:sqlserver://MyDbComputerNameOrIP:1433;databaseName=master",sUsr,sPwd);

7.ODBC

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

Connectionconn=DriverManager.getConnection("jdbc:odbc:"+sDsn,sUsr,sPwd);

8.DB2

Class.forName("Com.ibm.db2.jdbc.net.DB2Driver");

Stringurl="jdbc:db2://192.9.200.108:6789/SAMPLE"

conn=DriverManager.getConnection(url,sUsr,sPwd);
