SELECT with GROUP_CONCAT, GROUP BY, HAVING

Question

I Have table with odd_id and i want to select combinations for different ticket_id's. Here's my query:

SELECT
ticket_id,
GROUP_CONCAT(odd_id) as oddsconcat
FROM ticket_odds
GROUP BY ticket_id

And it gives me Following:

'28', '14472510,14472813,14472546,14472855,14472746,14472610,14472647'
'29', '14471149,14471138,14471125,14475603'
'30', '14471823,14471781,14471655,14471865,14471597,14471968,14471739,14471697,14471923'
'31', '14473874,14473814,14473862,14473838,14473790,14473802,14473826,14473850'
'32', '14471588,14472766,14471651,14471777,14471419'
'33', '14472647,14472605,14471650,14471734'
'34', '14471588,14472704,14471817'
'35', '14475279,14474499'
'282', '14472756,14472652,14472813'
'283', '14471588,14472766,14471419,14471777,14471651'
'284', '14474521'
'285', '14474529'
'286', '14474547'
'287', '14471134,14471199,14473636,14471242,14471398,14471237'

But if i use Having function, it doesn't give me results. Clearly: it gives me for the following:

SELECT
ticket_id,
GROUP_CONCAT(odd_id) as oddsconcat
FROM ticket_odds
GROUP BY ticket_id
HAVING oddsconcat = '14475279,14474499'

Returns ticket_id 35 and everyone is happy and code works fine, but if oddsconcat is larger then this one, it doesn't returns any value. for ex:

SELECT
ticket_id,
GROUP_CONCAT(odd_id) as oddsconcat
FROM ticket_odds
GROUP BY ticket_id
HAVING oddsconcat = '14473874,14473814,14473862,14473838,14473790,14473802,14473826,14473850'

Answer 1

I would rewrite it as:

SELECT 
ticket_id, 
GROUP_CONCAT(DISTINCT odd_id ORDER BY odd_id ASC) as oddsconcat 
FROM ticket_odds 
GROUP BY ticket_id 
HAVING oddsconcat = .....

Now the output in oddsconcat is determinatistic, because duplicates are eliminated and the items are in ascending order.
This should make matching much easier.
