Question

OK this is a bit tricky but basically in my SQL statement im comparing prices between fields in each row to get the lowest value returned, now the issue is that each value has a link.

Would there be a way to return the correct link depending on the lowest value in an SQL statement?

below is my SQL statement.

SELECT 
   title, 
   my_value, 
   my_ink,

   LEAST(site_a_value, site_b_value, site_c_value) AS lowest_value, 

   site_a_link,
   site_b_link,
   site_c_link

   FROM STOCK

so for example if site_b had the lowest value I would only want site_b_link to be returned.

Try

SELECT     title,
            my_value,
            my_ink,
            LEAST(site_a_value, site_b_value, site_c_value) AS lowest_value,     
            case LEAST(site_a_value, site_b_value, site_c_value)
            when site_a_value then site_a_link
            when site_b_value then site_b_link
            when site_c_value then site_c_link end AS lowest_value_link,
FROM STOCK
