大家好，请帮我看下我的这段代码怎么不能修改数据
conn = dataop.getConn();stmt = dataop.getStmt(conn);StringBuilder str = new StringBuilder("update topwellcrm.edu_person_info set edu_person_info.mobilePhone = '"+mobilePhone+"' where edu_person_info.username='"+username+"' ");//StringBuilder str_authority = new StringBuilder("select passwd from security_users where username='"+username+"'");String sql = str.toString();//System.out.println("打印sql");rs = stmt.executeQuery(sql);
谢谢大家


[解决办法]
楼主，你要修改代码的话就要用executeUpdate方法，executeQuery是查询数据
