Question

出现这个resultset cannot be resolved to a type怎么解？

String sql2="";
sql2="select top 5 * from youqinglianjie where 1=1";
sql2=sql2+" order by id desc";
ResultSet RS_result2=connDbBean.executeQuery(sql2);
String wangzhanmingcheng="";String wangzhi="";
//int i=0;
while(RS_result2.next()){
//i=i+1;
wangzhanmingcheng=RS_result2.getString("wangzhanmingcheng");wangzhi=RS_result2.getString("wangzhi");

%>

Answer 1

sql语句有问题啊。两个字符串链接是中间注意应该有空格。否则 where 1=1 order by 变成了 where 1=1order by 结果就没有了

Answer 2

可能是没有导sql包，在page行输入import="java.sql.*"
