【Java笔记】JDBC各数据库连接

 //1. jdbc-odbc数据源连接, jar库：不用
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String dbUrl = "jdbc:odbc:<数据源名>";  //要建立系统<数据源>
String userName = "";
String userPassword = "";
Connection conn = DriverManager.getConnection(url, userName,userPassword);

//2.access jdbc-odbc连接, jar库：不用
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String dbUrl = "jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};DBQ=<绝对路径_库名>";
String userName = "sa";
String userPassword = "123";
Connection conn = DriverManager.getConnection(url, userName,userPassword);

//3.oracle数据库连接,jar库：ojbc6.jar
Class.forName("oracle.jdbc.driver.OracleDriver");
String url = "jdbc:oracle:thin:@localhost:1521:<数据库实例名>";
String userName = "sa";
String userPassword = "123";
Connection conn = DriverManager.getConnection(url, userName,userPassword);

//4.sql server 2005数据库连接,jar库：jqsjdbc.jar
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String url = "jdbc:sqlserver://localhost:1433;databaseName=<数据库名>";
String userName = "sa";
String userPassword = "123";
Connection conn = DriverManager.getConnection(url, userName,userPassword);

//5.mysql 数据库连接,jar库：mysql-connector-java-5.0.8-bin.jar
Class.forName("com.mysql.jdbc.Driver");
String url = "jdbc:mysql://localhost:3306/<数据库名>?characterEncoding=gbk";
String userName = "sa";
String userPassword = "123";
Connection conn = DriverManager.getConnection(url, userName,userPassword);

 

以防遗忘，仅此做笔记。
