Question

There are 4 tables:

• Suppl, fields: (Code_name, Code_name_arch, Tasknum, Pki_num, Group_eng, Name, Descr, Cost, Quan, shop);

• Maker, fields : (Code_maker, Code_maker_arch, Code_name, provider);

• Arrival, fields: (Code_arr, Code_maker, quan_arr);

• Accounts, fields: (Code_acc, Code_maker, num_acc, quan_acc, summ)

my query is:

ALTER Procedure [dbo].[pr_tblz] As
Set NOCOUNT ON
Declare @task VARCHAR(4000)
Select @task = coalesce(@task + ',[' + [Tasknum] + ']',
'[' + [Tasknum] + ']')
FROM [db_pki].[dbo].[Suppl]
Group BY [Tasknum]
Order BY [Tasknum]
Declare @query VARCHAR(8000)
Set @query='
Alter View Amountzz As
SELECT Shop, Name, Desc, Group_eng as GI, '+ @task +', quan_arr As specif, quan_acc As acns 
FROM 
(
select
Shop, Name, Desc, Group_eng, Tasknum, Quan, quan_arr, quan_acc
from [db_pki].[dbo].[Suppl] as deliveries
LEFT JOIN [db_pki].[dbo].[Maker] ON (deliveries.[Code_name] = [db_pki].[dbo].[Maker].[Code_name])
LEFT JOIN [db_pki].[dbo].[Arrival] ON ([db_pki].[dbo].[Maker].[Code_maker] = [db_pki].[dbo].[Arrival].[Code_maker])
LEFT JOIN [db_pki].[dbo].[Accounts] ON ([db_pki].[dbo].[Maker].[Code_maker] = [db_pki].[dbo].[Accounts].[Code_maker])
)date_to_pivot
PIVOT 
(
Max([Quan])
For [Tasknum]
IN (' + @task + ')
 )AS p'
Execute (@query)

result:

Shop      Name     Descr    GI    n1     n2      n3 ...    specif    acns
1         name1      1       5    4                           1        1
2 10      name2      2       3    8                           2        2
3         name3      3       501         11                   3        3
1 8       name1      1       5           16                   7        10
a 2 10    name2      2       3                   3            5        6
5         name1      1       2                   5            6        3

How can I get the following result?

Shop      Name     Descr    GI    n1     n2      n3 ...    specif    acns
1 8       name1      1       5    4      16                 8(1+7)     11
a 2 10    name2      2       3    8              3            7        8(2+6)
3         name3      3      501          11                   3        3
5         name1      1       2                   5            6        3

n1, n2, n3,… – Tasknum

Not tested. Try aggregating the values of Shop, specif and acns in the subselect that pulls the columns before the pivoting, like this (the necessary changes are highlighted in bold):

ALTER Procedure [dbo].[pr_tblz] As
Set NOCOUNT ON
Declare @task VARCHAR(4000)
Select @task = coalesce(@task + ',[' + [Tasknum] + ']',
'[' + [Tasknum] + ']')
FROM [db_pki].[dbo].[Suppl]
Group BY [Tasknum]
Order BY [Tasknum]
Declare @query VARCHAR(8000)
Set @query='
Alter View Amountzz As
SELECT Shop, Name, Desc, Group_eng as GI, '+ @task +', quan_arr As specif, quan_acc As acns 
FROM 
(
select
MAX(Shop    ) OVER (PARTITION BY Name) AS Shop,
Name, Desc, Group_eng, Tasknum, Quan,
SUM(quan_arr) OVER (PARTITION BY Name) AS quan_arr,
SUM(quan_acc) OVER (PARTITION BY Name) AS quan_acc
from [db_pki].[dbo].[Suppl] as deliveries
LEFT JOIN [db_pki].[dbo].[Maker] ON (deliveries.[Code_name] = [db_pki].[dbo].[Maker].[Code_name])
LEFT JOIN [db_pki].[dbo].[Arrival] ON ([db_pki].[dbo].[Maker].[Code_maker] = [db_pki].[dbo].[Arrival].[Code_maker])
LEFT JOIN [db_pki].[dbo].[Accounts] ON ([db_pki].[dbo].[Maker].[Code_maker] = [db_pki].[dbo].[Accounts].[Code_maker])
)date_to_pivot
PIVOT 
(
Max([Quan])
For [Tasknum]
IN (' + @task + ')
 )AS p'
Execute (@query)
