SQL Query to convert multiple rows to a single row output

Question

I have the following sql query;
SELECT B.ClientID,
B.BillNo, B.[BillDate],
B.CurrencyCode,
B.BAmount
FROM tblCompanyDetails CD
CROSS
APPLY (
SELECT TOP 5 B1.ClientID,
 B1.[BillNumber],
B1.[BillDate], B1.[CurrencyCode] AS CCY,
 B1.[BillAmount]
FROM tblBills B1
WHERE ROUND(B1.[BillAmount],2)<>0
AND B1.ClientID=CD.CompanyID
AS B
WHERE CD.ContactId=235405
ORDER
BY B.ClientID,B.BillNo
DESC
This gives me the following row output;
ClientID
BillNo
BillDate
CurrencyCode
BAmount
94466
425616
2015-04-07
GBP
5000
94466
424517
2015-01-15
GBP
6000
94466
424455
2014-10-15
GBP
4000
However, I would like the ouput to appear like this;
ClientID
BillNo1
BillDate
CCY
BAmount
BillNo2
BillDate
CCY
BAmount
BillNo3
BillDate
CCY
BAmount
94466
 425616
 2015-04-07
 GBP
 5000
 424517
 2015-01-15
 GBP
 6000
 424455
 2014-10-15
 GBP
4000

I have tried to create a sample based on your question
CREATE TABLE MyTable
ClientID INT ,
BillNo INT,
BillDate DATE,
CurrencyCode varchar(5),
BAmount INT
INSERT INTO MyTable
VALUES (94466,425616,'2015-04-07','GBP',5000),
(94466,424517,'2015-01-15','GBP',6000),
(94466,424455,'2014-10-15','GBP',4000)
Then I have used another table to put ranking in that, you can actually tweak your statement to include rank also
CREATE TABLE RowTable
ClientID INT ,
BillNo INT,
BillDate DATE,
CurrencyCode varchar(5),
BAmount INT,
Ranking INT
INSERT INTO RowTable
SELECT * , ROW_NUMBER() OVER (ORDER BY ClientID) as row
FROM MyTable
Once your data is ready then execute below dynamic query
DECLARE @cols AS NVARCHAR(MAX),
@query AS NVARCHAR(MAX)
select @cols = STUFF((SELECT ',' + QUOTENAME(col+cast(Ranking as varchar(10)))
from RowTable
cross apply
select 'BillNo', 1 union all
select 'BillDate', 2 union all
select 'CurrencyCode', 3 union all
select 'BAmount' , 4
) c (col, so)
group by col, so, Ranking
order by Ranking, so
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set @query = 'SELECT ClientId,' + @cols + '
from
select clientid, col+cast(Ranking as varchar(10)) col, value
from RowTable
cross apply
SELECT ''BillNo'', cast(BillNo as varchar(20)) union all
SELECT ''BillDate'', cast(BillDate as varchar(20)) union all
SELECT ''CurrencyCode'', CurrencyCode union all
SELECT ''BAmount'', CAST(BAmount as varchar(10))
) c (col, value)
) x
pivot
max(value)
for col in (' + @cols + ')
) p '
execute sp_executesql @query;
Output: 
Hope this will help.
