String user="scott";
String password="root123";
Connection conn = DriverManager.getConnection(url, user, password);
// String sql="insert into t1 (id,name) values (1,'王')";
String sql="update stu set id=456 where name='vae'";
Statement st = conn.createStatement();
st.execute(sql);
st.close();
conn.close();
