Pivot not give expected result - sql

Question

I m using pivot and unpivot but I dot get expected output
Here is my sample data set
Table 1
id c_code
-----------------
123 1
456 1
Table 2
id c_code i_t_code i_code
----------------------
123 1 TWinc 10
123 1 TBinc 20
123 1 TSinc 30
Table 3
i_code i_t_code i_name
------------------------------
10 TWinc abc
20 TBinc xyz
30 TSinc pqr
Here is my query
Query
select * from (
select id,inc,i_t_code from (
select a.id,b.i_name,cast(b.i_code AS
VARCHAR(128)) as i_code,b.i_t_code
from
table_1 a
join
table_2 b
on a.id= b.id
and
a.c_code = b.c_code
join
tabl_3 c on c.i_code = b.i_code
and
c.i_t_code = b.i_t_code
on a.i_code = b.i_code
) d
Unpivot
(
inc for details in (i_name,i_code)
) as unpt) as uppt_res
PIVOT
(
max(inc)
FOR [i_t_code] IN ([TWinc],[TBinc],[TSinc])
) AS P
Expected output:
id TWinc_n TWinc_c TBinc_n TBinc_c TSinc_n TSinc_c
------------------------------------------------------------
123 abc 10 xyz 20 pqr 30
Actual output:
id TWinc TBinc TSinc
------------------------------------
123 abc xyz pqr
How can do this ??
It is possible using pivot or any other solution is there
can anyone help to fix this ?

You're going to have to give your data some variation if you want to stop pivot from compressing equal data items together when it's converting row data into column names and picking the max(inc) - probably easiest to do by changing the contents of the unpivoted data, tacking on a row number:
SELECT * FROM
(
select stoneid, inc, CONCAT(inclusion_type_id, ROW_NUMBER()OVER(PARTITION BY inclusion_type_id ORDER BY inc)) as inclusion_type_id FROM
(
select
a.stoneid,
b.inclusion_name,
cast(b.inclusion_code AS VARCHAR(128)) as inclusion_code,
b.inclusion_type_id,
b.inclusion_type_code
from
PACKET.STONE_LAB_INCLUSIONS a
inner join
MASTER.INCLUSION_MASTER b
on
a.inclusion_code = b.inclusion_code and
a.inclusion_type_code = b.inclusion_type_code
inner join
packet.stone_details c
on
c.stoneid = a.stoneid and
c.certificate_code = a.certificate_code
) d
UNPIVOT(inc for details in (inclusion_name,inclusion_code)) as unpt
) uppt_res
PIVOT
(
MAX(inc)
FOR [inclusion_type_id] IN ([TWinc1],[TWinc2],[TBinc1],[TBinc2],[TSinc1],[TSinc2])
) AS P
If you're desperate to have column names the same, you can alias the results of this query rather than select *
