Linked server query using Dynamic SQL

Question

I have a Linked server query that takes forever to run. WHen I hardcode the acct# it runs fast. However I want these acct numbers int he where clause to be generated dynamically. For eg: below is what I need:
--Get the 11 Loans from this Table A From the FIRST QUERY
--- Plug those loans numbers in the second query  In the WHERE Clause eg should looks like  where  ACCT in (1,2,3,5)
DECLARE
@sSQL varChar(MAX)
SET @sSQL
=
' SELECT
[Loan] FROM TableA D
EXECUTE(@sSQL)
--2ND QUERY 
DECLARE
@sSQL1 varChar(MAX)
SET @sSQL1
='
SELECT Field1, 
Field2,
Field3,
Field4,
Field5
   FROM LinkedServer.Dbaname.dbo.TableB a
where ACCT in ''('''
+(@sSQL)
+
''')'''--- This needs to look like  where  ACCT in (1,2,3,5)
select
@sSQL1

Ok, so use this.. instead of your first statement.
DECLARE @sSQL NvarChar(MAX), @output NVARCHAR(100), @ParmDefinition nvarchar(500);
SET @ParmDefinition = N'@sqlout NVARCHAR(100) OUTPUT'
SET @sSQL = N'SELECT DISTINCT @sqlout = STUFF((SELECT '',''+CAST(S2.loan AS VARCHAR(100))
FROM tableA S2
FOR XML PATH('''')), 1, 1, '''')
FROM tableA S1'
EXECUTE sp_executesql @sSQL, @parmdefinition, @sqlout = @output OUTPUT
and use @output instead of @sSQL in the second statement.
