adding a sql to my wordpress database

Hi,
I am very new to javascript and ajax. I have a project where I want to create a like button (not social media) multiple times on a page. I think I found some code but it requires me to add a sql file to my database.

The file basically created a table for the likes.

Is there anything I should be concerned about adding this file to create a table in my wordpress database?

Do I need to create a new database?

Can I import the file through the wordpress import or do I need cpanel and mysql access?

Thank you for any help anyone can provide.

Lisa
