SqlServer、Oracle、MySQL的连接,除了地址和驱动包不同,其他都一样的。
1 public String urlString="jdbc:sqlserver://localhost:1433;databaseName=crebas;";
2 //"jdbc:mysql://localhost:3306/crebas?autoReconnect=true&useUnicode=true&characterEncoding=utf8"
3 //"jdbc:oracle:thin:@localhost:1521:ORCL"
4 public String nameString="sa";
5 public String password="123";
6 public void test()
7 {
8 String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
9 //"com.mysql.jdbc.Driver"
10 //"oracle.jdbc.driver.OracleDriver"
11 try
12 {
13 Class.forName(driver);
14 Connection conn = DriverManager.getConnection(urlString, nameString, password);
15 PreparedStatement pstmt = conn.prepareStatement("Select * from T_Admin");
16 ResultSet rs = pstmt.executeQuery();
17 rs.next();
18 System.out.println(rs.getString(1));
19 System.out.println(rs.getString(2));
20 System.out.println(rs.getString(3));
21 } catch (Exception e)
22 {
23 e.printStackTrace();
24 }
25 }
最基础的连接方式,好久之前整理的了,备忘一下。
