介绍mysql,oracle,sqlserver2000,postgresql的连接方法,这些都是我的心得

加载驱动
//MySql
Class.forName("com.mysql.jdbc.Driver");
//postgresql
Class.forName("org.postgresql.Driver");
//oracle
Class.forName("oracle.jdbc.driver.OracleDriver");
//Sybase
Class.forName("com.sybase.jdbc2.jdbc.SybDriver");
//SQLServer
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
//DB2
Class.forName("com.ibm.db2.jdbc.net.DB2Driver");


建立连接
//MySql
Connection conn=DriverManager.getConnection("jdbc:mysql://[MyDbComputerNameorIP]:3306/[myDBName]",ID,Pswd);
//postgersql
Connection conn=DriverManager.getConnection("jdbc:postgresql://[MyDbComputerNameorIP]:3306/[myDBName]",ID,Pswd);
//Oracle
//thin连接方式本地什么都不需要安装
Connection conn=DriverManager.getConnection("jdbc:oracle:thin:@[MyDbComputerNameorIP]:1521:[DbName]",ID,Pswd);
//oci8的连接方式在本地至少要安装一个oracle的客户端
Connection conn = DriverManager.getConnection("jdbc:oracle:oc18:@[DbName]1521","system","system_manager");
//Sybase
Connection conn=DriverManager.getConnection("jdbc:sybase:Tds:[MyDbComputerNameorIP]:2638",ID,Pswd);
//SQLServer
Connection conn=DriverManager.getConnection("jdbc:microsoft:sqlserver://[MyDbComputerNameorIP]:1433;databaseName=[myDBName]",ID,Pswd);
//DB2
Connection conn=DriverManager.getConnection("jdbc:db2://[MyDbComputerNameorIP]/[myDBName]",ID,Pswd);
