With PHP and MySQL I'm attempting to display products with many votes on the certain time period (round-the-clock, 7 days, 12 months, etc). When someone votes with an item, a table records the consumer, item id, election, and time, like so:

Table1

username |  itemid | vote | time
   asdf  |    127  |   1  |  1306726126
   asdf  |    124  |  -1  |  1306726123
    bob  |    127  |   1  |  1306726129
    bob  |    124  |   1  |  1306726123

Now, I've another table with item particulars.

Table2

itemid  | name  | category | date | etc

What I wish to do is call a table to show all of the data from table 2 for just products with votes within the last 24hours and sort it through the votes. What this means is I have to SUM votes as time passes < 24 hrs, then RIGHT JOIN (?) to my other database? I'm not sure, I'm getting difficulty determining the way i is going about carrying this out. Any suggestiongs?

Something similar to this will work.

SELECT SUM(Table1.vote) as votes, Table2.* FROM Table2            
    LEFT JOIN Table1 ON Table1.itemid=Table2.itemid                
    WHERE Table1.`time`>=DATE_SUB(Table1.`time`, INTERVAL 24 HOUR) 
GROUP BY Table1.itemid                                             
ORDER BY Table1.votes DESC
