java連接達夢數據庫的簡單代碼

1. 引用DmJdbcDriver.jar包

2. 編寫代碼：

String driver= "dm.jdbc.driver.DmDriver";
String url= "jdbc:dm://192.168.1.100:12345/TEST";
String username="DEVELOPER";
String password="123456";

Class.forName(driver);
Connection conn = DriverManager.getConnection(url, username, password);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select * from OaUser");
int newID = 1;
if (rs.next()) {

    String userName = rs.getString("UserName");
    out.println("userName:" +userName);

}else{
    out.println("no data");
}
rs.close();
conn.close();
