java.sql.SQLException: ORA-01002: 提取违反顺序

[Waitforsniping]

public UserAccount findUserAccount(UserAccount user)
{
Connection conn = DBTool.getInstance().getConnection();
PreparedStatement ps = null;
ResultSet rs = null;

String id = user.getUserId();
String newuserPsw = user.getUserPsw();

System.out.println("yizhixing001");

try{
ps = conn.prepareStatement("UPDATE BBS_USER SET USERPSW = ' "+newuserPsw+"'
WHERE USERPSW ="+id);
rs = ps.executeQuery();
while(rs.next()){
user = new UserAccount();
user.setUserId(rs.getString("userId"));
user.setUserPsw(rs.getString("userPsw"));
user.setPswquestion(rs.getString("pswquestion"));
user.setPspanswer(rs.getString("pspanswer"));
System.out.println("002");
}
}
catch (SQLException e)
{
e.printStackTrace();
}
finally
{
DBTool.closeAll(conn, ps, rs);
}

return user;

}


yizhixing001能输出，002不能输出，异常就是java.sql.SQLException: ORA-01002: 提取违反顺序，求解释啊

你执行的是UPDATE语句，没有结果集返回，改成SELECT语句吧。
