I always use auto_increment when making tables. Right now I’m trying to make a table for an html <select> field but the problem is that it’s set to optional so the first <option>...</option> will have to have a value of 0. Does that mean that when I structure the table the first auto_increment will have to start at 0 as well? Is that even valid?

Edit: Thanks for your comments. I’ll be using the table in some INNER JOIN statement so the primary key is a foreign key in some other table. What will the value of the foreign key be if the user doesn’t opt to answer the field?

    You can’t use auto_increment if you need to start counting at 0 (not valid).

    You could, however, hard-code your default <option> in HTML.
