Question

I have a table called items. IN this table there are many columns. One of the columns is called ‘source’. What I would like to do is select records from the table. I would like to select the latest 5 records with the condition that the ‘source’ columns are all distinct.

I tried the following:

SELECT DISTINCT SOURCE from items order by time DESC LIMIT 5

but I need the whole record not just the source, when I try to include more columns it doesn’t work .

I tried this:

SELECT * FROM items  WHERE item_section='sp_500'   GROUP BY source  ORDER BY time DESC    LIMIT 3

but it doesn’t give me the LATEST records

Answer 1

Tricky.

Try this.

SELECT items.* 
  FROM items
  INNER JOIN 
    (SELECT source, max(time) maxtime
       FROM bbc
       GROUP BY source
       ORDER BY max(time) DESC
       LIMIT 5
    ) s
ON items.source = s.source and items.time = maxtime
