Connection conn=DatabaseBean.getConnection();
String sql= "select max_id from tableseq where table_name= 'category ' ";
//int i=DatabaseBean.getMaxId( "category ");
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery(sql);
ResultSetMetaData rsmd=rs.getMetaData();
int i=rsmd.getColumnCount();
String str=rsmd.getColumnTypeName(1);
%>
<%=rs.getInt(1) %>
数据库可以连接,也可以进行操作,但就是最后那句 <%=rs.getInt(1) %> 差不出结果, 求高人指点
------解决方案-------------------- <%=rs.getInt( "max_id ")%>
------解决方案--------------------max_id 是 int 类型?
