Bet Table:
BetId, int
BetName, nvarchar
BettypeId, int

Bettype Table:
BettypeId, int
BettypeName, nvarchar

BookMaker Table:
BookMakerId, int
BookMakerName, nvarchar
SortOrder, int

Odds Table:
OddsId, int
BookMakerId, int
BettypeId, int
BetId, int
MatchId, int
FixtureId, int
OddsValue, nvarchar (e.g. 31/11, it is a fraction)

SQL:
SELECT COUNT(BetId) FROM [Bet] where BettypeId = 1
It can count how many Bet under a Bet type.
Result: 3

SELECT * FROM [odds] where MatchId=116 and BettypeId = 1 and
BetId in (SELECT BetId FROM [Bet] where BettypeId = 1)
order by BookMakerid, BetId
Result:
2355 1 1 1 116 116 11
2333 1 1 2 116 116 9/2
2311 1 1 3 116 116 1/4
2356 2 1 1 116 116 11
2334 2 1 2 116 116 9/2
2312 2 1 3 116 116 1/4
2357 3 1 1 116 116 9
2335 3 1 2 116 116 9/2
2313 3 1 3 116 116 2/7
2358 4 1 1 116 116 8
2336 4 1 2 116 116 9/2
2314 4 1 3 116 116 1/4
2359 5 1 1 116 116 9
2337 5 1 2 116 116 9/2
2315 5 1 3 116 116 2/7
2360 6 1 1 116 116 9
2338 6 1 2 116 116 19/4
2316 6 1 3 116 116 1/4

Target output:
BookMakerId=1, BookMakerName, BetId=1, BetName, OddsValue, BetId=2, BetName, OddsValue, BetId=3, BetName, OddsValue
BookMakerId=2, BookMakerName, BetId=1, BetName, OddsValue, BetId=2, BetName, OddsValue, BetId=3, BetName, OddsValue
BookMakerId=3, BookMakerName, BetId=1, BetName, OddsValue, BetId=2, BetName, OddsValue, BetId=3, BetName, OddsValue
BookMakerId=4, BookMakerName, BetId=1, BetName, OddsValue, BetId=2, BetName, OddsValue, BetId=3, BetName, OddsValue
BookMakerId=5, BookMakerName, BetId=1, BetName, OddsValue, BetId=2, BetName, OddsValue, BetId=3, BetName, OddsValue
BookMakerId=6, BookMakerName, BetId=1, BetName, OddsValue, BetId=2, BetName, OddsValue, BetId=3, BetName, OddsValue

If the number of BetId changes, the columns (a set of BetId, BetName, OddsValue) will be adjusted.

Sort by OddsValue for 3 Bet of 3 bookmakers:
BetId=1, BetName, OddsValue (Highest value put in 1st row)
BetId=2, BetName, OddsValue (Highest value put in 2nd row)
BetId=3, BetName, OddsValue (Highest value put in 3rd row)

How is the SQL?

[code]
SELECT o.BookMakerId,bm.BookMakerName,
MAX(CASE WHEN o.BetId =1 THEN o.BetId END) AS BetId1,
MAX(CASE WHEN o.BetId =1 THEN b.BetName END) AS BetName1,
MAX(CASE WHEN o.BetId =1 THEN o.OddsValue END) AS OddsValue1,
MAX(CASE WHEN o.BetId =2 THEN o.BetId END) AS BetId2,
MAX(CASE WHEN o.BetId =2 THEN b.BetName END) AS BetName2,
MAX(CASE WHEN o.BetId =2 THEN o.OddsValue END) AS OddsValue2,
MAX(CASE WHEN o.BetId =3 THEN o.BetId END) AS BetId3,
MAX(CASE WHEN o.BetId =3 THEN b.BetName END) AS BetName3,
MAX(CASE WHEN o.BetId =3 THEN o.OddsValue END) AS OddsValue3
FROM [Odds] o
INNER JOIN [BookMaker] bm
ON bm.BookMakerid = o.BookMakerid
INNER JOIN [Bet] b
ON b.BetId = o.BetId
GROUP BY o.BookMakerId,bm.BookMakerName

I tried and modifed your SQL and has one last problem about the sorting of OddsValue which is a Fraction with nvarchar datatype:

SELECT o.BookMakerId,bm.BookMakerName,
MAX(CASE WHEN o.BetId=1 and MatchId=53 THEN o.BetId END) AS BetId1,
MAX(CASE WHEN o.BetId=1 and MatchId=53 THEN b.BetName END) AS BetName1,
MAX(CASE WHEN o.BetId=1 and MatchId=53 THEN o.OddsValue END) AS OddsValue1,
MAX(CASE WHEN o.BetId=2 and MatchId=53 THEN o.BetId END) AS BetId2,
MAX(CASE WHEN o.BetId=2 and MatchId=53 THEN b.BetName END) AS BetName2,
MAX(CASE WHEN o.BetId=2 and MatchId=53 THEN o.OddsValue END) AS OddsValue2,
MAX(CASE WHEN o.BetId=3 and MatchId=53 THEN o.BetId END) AS BetId3,
MAX(CASE WHEN o.BetId=3 and MatchId=53 THEN b.BetName END) AS BetName3,
MAX(CASE WHEN o.BetId=3 and MatchId=53 THEN o.OddsValue END) AS OddsValue3
FROM [WinnerOdds] o
INNER JOIN [BookMaker] bm
ON bm.BookMakerid = o.BookMakerid
INNER JOIN [Bet] b
ON b.BetId = o.BetId
GROUP BY o.BookMakerId,bm.BookMakerName
Order by convert(float, OddsValue1) desc, convert(float, OddsValue2) desc, convert(float, OddsValue3) desc

It throws the following errors:
Msg 207, Level 16, State 1, Line 17
Invalid column name 'OddsValue1'.
Msg 207, Level 16, State 1, Line 17
Invalid column name 'OddsValue2'.
Msg 207, Level 16, State 1, Line 17
Invalid column name 'OddsValue3'.

Here is the output without the order by statement:
1 Bookies1 1 Home 16/5 2 Draw 13/5 3 Away 5/6
18 Bookies2 1 Home 13/5 2 Draw 23/10 3 Away 5/6
10 Bookies3 1 Home 3 2 Draw 12/5 3 Away 10/11

How should fraction sorting be fixed?

just make it


SELECT *
FROM
(
SELECT o.BookMakerId,bm.BookMakerName,
MAX(CASE WHEN o.BetId=1 and MatchId=53 THEN o.BetId END) AS BetId1,
MAX(CASE WHEN o.BetId=1 and MatchId=53 THEN b.BetName END) AS BetName1,
MAX(CASE WHEN o.BetId=1 and MatchId=53 THEN o.OddsValue END) AS OddsValue1,
MAX(CASE WHEN o.BetId=2 and MatchId=53 THEN o.BetId END) AS BetId2,
MAX(CASE WHEN o.BetId=2 and MatchId=53 THEN b.BetName END) AS BetName2,
MAX(CASE WHEN o.BetId=2 and MatchId=53 THEN o.OddsValue END) AS OddsValue2,
MAX(CASE WHEN o.BetId=3 and MatchId=53 THEN o.BetId END) AS BetId3,
MAX(CASE WHEN o.BetId=3 and MatchId=53 THEN b.BetName END) AS BetName3,
MAX(CASE WHEN o.BetId=3 and MatchId=53 THEN o.OddsValue END) AS OddsValue3
FROM [WinnerOdds] o
INNER JOIN [BookMaker] bm
ON bm.BookMakerid = o.BookMakerid
INNER JOIN [Bet] b
ON b.BetId = o.BetId
GROUP BY o.BookMakerId,bm.BookMakerName
)t
Order by convert(float, OddsValue1) desc, convert(float, OddsValue2) desc, convert(float, OddsValue3) desc
