MySQL Selection problem

I have two tables on database user and ads when user visit the ads page I want to show him only the ads related to his country in the ads table , there is field called contry where I insert related countries like that country="Country1;Coutry2;Country3;..." and every user have a field with his country name How to select ads from ads table where the user's coutry 开发者_高级运维is in the country field I guess something like that

SELECT * FROM ads WHERE $usercoutry IN ads.country

Thanks for All , I found the solution

SELECT * FROM ads WHERE coutry LIKE '%{$usercountry}%' 

That Code solved the problem :)

SELECT * FROM ads WHERE country like '%$usercoutry%'

You could try:

SELECT * FROM ads WHERE ads.country = $usercountry

Are you trying to do something like the following?

SELECT * FROM ads WHERE ads.country like '%' || $usercountry || '%';

Nota: you should use a parameter (eg a prepared statement with '?' in the query), and set the concatenated string as its value, in order to avoid SQL injection - if it's a concern.

Need to use LIKE with the variable encased in braces:

SELECT * FROM ads WHERE country LIKE '%{$usercountry}%';
