But you haven't written anywhere that line in the query i.e,
'+@columnname,details and ('+@columnname+')

Can you share the actual error message?

i have written it as u see once again
declare @columnname as varchar(100)
select @columnname=ISNULL(@columnname+',','')+QUOTENAME(Expenses_Name) from (select distinct Expenses_Name from dbo.Expenses) as Expenses_Name
select * from
(
select dbo.CreditDebit.ID as SLNO,TransactionDate,Particular,Balance,Expenses,Credit_Expenses,Debit_Expenses,','+@columnname
FROM DBO.CreditDebit
INNER JOIN DBO.CreditExpenses
on dbo.CreditDebit.ID=dbo.CreditExpenses.Credit_ID inner join
dbo.Expenses on dbo.Expenses.ID=dbo.CreditExpenses.Expenses_ID

dynamic Pivot does not work until and unless you use dynamic query. i.e. you need to prepare a query string with dynamic columns and then execute it.

Member 11882484 12-Jul-16 7:56am

ya but how to do that .if u know than say me..Here is my query
declare @expenseNames nvarchar(max) = '';
select @expenseNames += case when datalength(@expenseNames) = 0 then '' else ', ' end + '[' + ltrim(rtrim(Expenses_Name)) + ']'
from expenses
declare @dynamicSQL nvarchar(max)='';
set @dynamicSQL =
'select * from
(select dbo.CreditDebitExpenses.ID AS SLNO, TransactionDate, Particular,Expenses_Name,Debit_Expenses,Credit_Expenses,Expenses,
Balance from dbo.CreditDebitExpenses inner join
dbo.CreditExpenses on dbo.CreditDebitExpenses.ID=dbo.CreditExpenses.Credit_ID
inner join dbo.Expenses on dbo.CreditExpenses.Expenses_ID=dbo.Expenses.ID
)src
pivot
(
sum(Expenses)
for Expenses_Name In (' +@expenseNames+ ')
)as pvt'
here i am using it by dynamically but its return as -1
