how to convert all row data as column names in sql server.

the problem is that, I want to get all the data as column name without specifying column like A1,A2,B1,C1 is there is any other way to achieve the result and in here I don't want to use any aggregate function like sum or count so what is the procedure to get column name without using sum([Uid])


LIKE :INTPUT=>
ITEM
-----
A1
A2
B1
C1
OUTPUT =>
A1 | A2 | B1 | C1
-------------------
which mean column A1,A2,B1,C1

What I have tried:

Declare @Str1 nvarchar(max)
select @Str1=(SELECT TOP 1
STUFF((
        SELECT DISTINCT ',' + Items 
        FROM ItemMaster
        FOR XML PATH('')
    ), 1, 1, ''
) as columnlist
FROM ItemMaster)

select
  *
from
  (select AddPayslip,Items from ItemMaster where AddPayslip=1 and DeleteStatus=0) p
pivot (
  count([AddPayslip]) for Items in ([@Str1])
) pivoted

select @Str1;

What is category meant to be? It's not in your sample data

1 solution

Here is an example of a working pivot based loosely on your sample data
SQL
declare @itemMaster table (Item varchar(3), amount decimal(15,2));
insert into @itemMaster (Item, amount) values
('A1',100),('A2',200),('B1',1000),('C1',10000);

select
  *
from
  (select Item,amount from @ItemMaster) p
pivot (
  sum([amount]) for Item in (A1, A2, B1, C1)
) pivoted
This CP article gives some guidance Simple Way To Use Pivot In SQL Query[^]

From the OP comments below I think they might just need those items in a character separated list rather than a pivot on values. Here are some ways to achieve that
1. From SQL Server 2017 you can use STRING_AGG
SQL
SELECT STRING_AGG(item, '|') as columnlist from @itemMaster

2. In earlier versions you can use FOR XML e.g.
SQL
SELECT TOP 1
STUFF((
        SELECT DISTINCT '|' + Item 
        FROM @itemMaster
        FOR XML PATH('')
    ), 1, 1, ''
) as columnlist
FROM @itemMaster
3. For even earlier versions you can use a Common Table expression e.g.
SQL
DECLARE @listStr VARCHAR(MAX) = null
;WITH cteitems AS
(
    SELECT DISTINCT Item from @itemMaster
)
SELECT  @listStr = COALESCE(@listStr+'|' ,'') + Item
FROM @itemMaster
select @listStr
All of the above give the output
A1|A2|B1|C1
without knowing what values exist

Yeah its correct but the problem is i want to get all the data as column name without specifying column like A1,A2,B1,C1 is there is any other way to achieve the result and in here i don't want to use any aggregate function like sum or count so what is the procedure to get column name without using sum([amount])

Yes - you can use dynamic SQL - there is an example in my article Processing Loops in SQL Server[^]
CHill60 14-Oct-22 9:37am    
On the rest of it - you have to use an aggregate function - that is the syntax. What are you planning to put in the columns?

Okey i understand now thankyou for the information
