I have some values which are repeating in my table, I want to select only those with the latest/highest date i.e :

ID   Type     Name      Value        Date
--  -------   -----    -------       -------------
1   "FRUIT"  "APPLE"  "Imported"  "2011-03-19 22:08:13"
5   "FRUIT"  "LEMON"  "Imported"  "2011-03-19 22:00:44"
22  "FRUIT"  "PEACH"  "Imported"  "2011-03-20 11:03:13"
31  "FRUIT"  "MELON"  "Imported"  "2011-04-28 18:42:07"
44  "FRUIT"  "PEACH"  "Imported"  "2011-04-12 11:06:11"
98  "FRUIT"  "CHERRY" "Imported"  "2011-03-19 22:46:04"
211 "FRUIT"  "MELON"  "Imported"  "2011-03-19 22:25:24"
217 "VEG"    "SPINACH""Imported"  "2011-03-19 22:25:24"

I’d like to select these : 

ID   Type     Name      Value        Date
--  -------   -----    -------       -------------
1   "FRUIT"  "APPLE"  "Imported"  "2011-03-19 22:08:13"
5   "FRUIT"  "LEMON"  "Imported"  "2011-03-19 22:00:44"
31  "FRUIT"  "MELON"  "Imported"  "2011-04-28 18:42:07"
44  "FRUIT"  "PEACH"  "Imported"  "2011-04-12 11:06:11"
98  "FRUIT"  "CHERRY" "Imported"  "2011-03-19 22:46:04"

This is simplified version of what I need, my table has about 20 columns so I want select *, if not I can select one by one.

So I want to select * rows of Type FRUIT but select only those with highest date. Thank you

    This should give you what you want:

    SELECT *
FROM Table
INNER JOIN 
(SELECT Name, MAX(Date) as TopDate
FROM Table
WHERE Type = 'FRUIT'
GROUP BY Name) AS EachItem ON 
    EachItem.TopDate = Table.Date 
    AND EachItem.Name = Table.Name

    Basically, it will find the latest date for each type of fruit and then display each fruit with the information for the row (joined on the date and fruit name). Make sure the Date field and Name field are both indexed.

    If you could assume that the item with the highest ID would also be the one with the highest date (typical but not necessarily true in all cases – it depends on your use case), you could do MAX(ID) instead of MAX(Date) and take advantage of just linking by that ID instead of linking by Date and Name.
