试图从mysql数据库获取用户详细信息出错

Question

我试图通过使用以下查询来获取mysql数据库的用户详细信息

                    $rows=array();
         $query = "SELECT CONCAT(usrFirstname,'',usrSurname) As FullName,usrNickname AS            Nickname,";
      $query.= "usrEmail As EmailAddress,usrGender AS Gender,DATE_FORMAT(usrDOB,'%d%m%y') As DOB,usrBelt AS BeltId";
      $query.= "FROM user";
      $result = mysql_query($query);
     echo mysql_error();
if($result)
{
  while($row=mysql_fetch_assoc($result))
  {
       $rows[] = $row;
  }
}

它给出了这样的错误

错误：              您的SQL语法有错误;查看与MySQL服务器版本对应的手册，以便在第1行的“用户”附近使用正确的语法

Answer 1

尝试在from

之前添加空格

$query.= " FROM user";

Answer 2

usrBelt AS BeltId和FROM之间没有空格。

Answer 3

您在单词FROM前面缺少空格。

  $query.= "usrEmail As EmailAddress,usrGender AS Gender,DATE_FORMAT(usrDOB,'%d%m%y') As DOB,usrBelt AS BeltId";
  $query.= " FROM user";
