在向数据库查询时,传入的中文变成乱码,求解决方案
ps=conn.prepareStatement("select * from user where pwd=?,nickname=?");
ps.setString(1, pwd);
ps.setString(2, nickname);
pwd 是英文,nickname是中文,每次查找的时候都提示You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' nickname = '???????‘?'' at line 1
这个问题,向数据库插入的时候就没有问题,不是为什么查找就不行,知道的大神帮下忙啊!

------解决方案--------------------
晕,你的SQL语句写错了,应该是select * from user where pwd=? and nickname=?
------解决方案--------------------
Connection con=DriverManager.getConnection(conURL);
Statement s=con.createStatement();
ResultSet rs=s.executeQuery("select *from vip");
int i=0;
while(rs.next())
{

s1=rs.getString("nickname");
s2=rs.getString("pwd");
i++;

}
