MYSQL的数量选择和限制“组由”

Question

我的查询如下：

  $query = "SELECT report,"; 
      $query.= "GROUP_CONCAT(DISTINCT analyst) AS analysts, "; 
      $query.= "GROUP_CONCAT(DISTINCT region) AS regions, "; 
      $query.= "GROUP_CONCAT(DISTINCT country) AS countries, "; 
      $query.= "GROUP_CONCAT(DISTINCT topic) AS topics, "; 
      $query.= "GROUP_CONCAT(DISTINCT date) AS dates, "; 
      $query.= "GROUP_CONCAT(DISTINCT link) AS links, "; 
      $query.= "GROUP_CONCAT(DISTINCT province) AS provinces "; 
      $query.= "FROM reports GROUP BY report ORDER BY dates DESC "; 

我想为MySQL到GROUP BY报告，并且还（报告），该数量限制为10。有什么建议么？

只需将LIMIT 10添加到您的查询结尾。
