Question

所以我从twitter下载了这个评论文件，但问题是post_by，comment_id，comment_by是如此巨大的数字，我无法在这个csv文件中读入mysql表。

post_by post_text   post_published  comment_id  comment_by  is_reply    comment_message likes

我使用的代码是抛出错误，因为日期/时间戳被读作主键，我没有任何关于它为什么会发生的线索。

mysql> CREATE TABLE test (
    -> id INT(50) UNSIGNED  ,
    -> post_id INT(50) UNSIGNED ,
    -> post_by INT(50) UNSIGNED,

    -> is_reply INT (2),
    -> comment_message LONGTEXT,
    -> comment_published TIMESTAMP,
    -> comment_like_count INT(10)
    -> );

我面临的其他问题： -

1。）如何处理这些ID之间的“ - ”/连字符？ 2.）如何保存这些巨大的ID？
