Data select advice

[Arsench]

Hi all,
I have a table curs_period where inserting some data to send them via email, this table contains data for 1st email

Id = Auto increment
Name = Madrid
Period = 01/11 to 01/12

Then I have another data for 2nd email

Id = Auto increment
Name = Madrid
Period = 01/01 to 01/02

The both emails I have to send to the users where the user can click on the link, and the page must be loaded with the correct data. How to do select query correctly to avoid select 1st email’s data when clicking on the 2nd email’s link?

Thanks in advance.

It seems that you would want to make the ID a parameter in the link so you can find the right one.

Thanks for replay,
Every register has a ID but how could I find it and assign to the link?

Thank you
