[求助]修改sql表信息,要嵌套的
我是分页显示信息的,当我要修改某条记录时,只要点击修改,那么所有关于这条(id)信息的记录就会显示出来,我们可以选择性的修改.但我点击时出现了这样的错误:Invalid operation for the current cursor position.点击修改的事件是<a href="pyxiugai.jsp?bianhao=<%=rs1.getString("bianhao")%>">修 改</a> ,但我点击删除这条信息时又可以,点击删除的事件是<a href="pydelete.jsp?bianhao=<%=rs1.getString("bianhao")%>">删除</a>.希望有高人相助
我的源代码是
<% request.setCharacterEncoding("gb2312");%>
