简单地说,JDBC 可做三件事:与数据库建立连接、发送 SQL 语句并处理结果。下列代码段给出了以上三步的基本示例:
Connection con = DriverManager.getConnection("jdbc:odbc:wombat","login", "password");
Statement stmt =con.createStatement();
ResultSet rs =stmt.executeQuery("SELECT a, b, c FROM Table1");
while (rs.next()) {
int x = rs.getInt("a");
String s = rs.getString("b");
float f = rs.getFloat("c");
}
