Apache Tomcat/6.0.13 --------------------编程问答-------------------- 我做的是一个在线投票系统,执行增加主题的操作时报了这个错。
这是那一段的代码
String submit1=request.getParameter("submit1"),str="",optContent,sql;
int id;
if(submit1!=null){
sql="insert into vote(flag,optType,question) values(0,"+optType+",'"+question+"')";
java.executeUpdate(sql);
sql="select * from vote order by id desc";
ResultSet rs=java.executeQuery(sql);
id=rs.getInt(1);
for(int i=1;i<=num;i++){
str=Integer.toString(i);
optContent=request.getParameter(str);
sql="insert into vote(flag,optContent,number) values("+id+",'"+optContent+"',0)";
java.executeUpdate(sql);
}
out.print("成功插入主题!");
} --------------------编程问答-------------------- 是不是数据无法写入数据库表导致的这个报错啊,求解决方案。 --------------------编程问答-------------------- ResultSet rs=java.executeQuery(sql);
rs.next();
id=rs.getInt(1); --------------------编程问答-------------------- 还是不行啊。
