What I normally do in such a case, is using a tool like Navicat to write a query that gives me exactly the columns I need, ordered in the way I need them, and then use the export function of the tool to save the result in an Excel file.在这种情况下，我通常会使用 Navicat 之类的工具编写一个查询，该查询准确地提供了我需要的列，按照我需要的方式排序，然后使用该工具的 export function 将结果保存在Excel 文件。
That way I get all the Excel (or OpenOffice, for that matter) options for printing, including scaling to get as much records on one page as possible.这样我就可以获得所有 Excel（或 OpenOffice，就此而言）选项进行打印，包括缩放以在一页上获得尽可能多的记录。

You could query as normal and use PHP to write the results to a CSV file for further formatting, printing, etc. http://php.net/manual/en/function.fputcsv.php You could query as normal and use PHP to write the results to a CSV file for further formatting, printing, etc. http://php.net/manual/en/function.fputcsv.php
I don't think 1 million rows will be too much, but it will depend on your hardware (memory), environment (php timeouts), and the actual data.我认为 100 万行不会太多，但这取决于您的硬件（内存）、环境（php 超时）和实际数据。 The paper itself might be a problem, though.不过，论文本身可能是个问题。
