Where clause as a Paramter?

Question

So i am using a view for my report and my question is can i have a where clause parameter
select * from vw_rpt_inv_report
where=@where?
The reason i want to use that is when my report is executed my view has 28 columns right so a user should be able to use any column from my report as a parameter.
Does that make any sense ?
I did some research and i found this as a solution :
declare @whereclause nvarchar(1000)
set @whereclause= 'select * from vw_rpt_inv_standard_format'
select i.*, L.COMPANYNAME, L.LOCATIONNAME, L.ADDRESSLINE2, L.CITY, L.STATE, L.COUNTRY, L.ZIPCODE
FROM VW_RPT_INV_STANDARD_FORMAT I
JOIN LOCATION L ON L.LOCATIONID=I.LOCATIONID
WHERE ' + @whereclause '
When i try to run the report i get an error
ORA-06550: line 1, column 9:
PLS-00103: Encountered the symbol "@" when expecting one of the following:
begin function package pragma procedure subtype type use
<an identifier> <a double-quoted delimited-identifier> form
current cursor
The symbol "@" was ignored.
ORA-06550: line 1, column 36:
PLS-00103: Encountered the symbol "" when expecting one of the following:
:= ; not null default character
I am using ORACLE AS my Database for creating reports on MS SSRS 2008.
Can anyone help me ?

Okay i am brand new to this so i am totally lost.
What i am trying to do is i have a view which is my dataset right
select * from vw_inv_report.
once my report is done its deployed on a webservice.
I have a report built on a query and I want to be able to send a parameter (@theWhere) that is a string which is a where clause (WORKORDERNUMBER LIKE '1563514%') and locationid in(63) these strings can vary depending on what columns the user selects and what operators they want to use. Generation of proper SQL for the where clause has been verified, I just need to be able to pass these, is there any way to do this...see example query below and how I was planning on using the @theWhere variable...
So can i use
declare @where nvarchar(1000)
declare @clause nvarchar(5000)
set @where= '(WORKORDERNUMBER LIKE '1563514%') and locationid in(63) '
set @clause =
'select i.*, L.COMPANYNAME, L.LOCATIONNAME, L.ADDRESSLINE2, L.CITY, L.STATE, L.COUNTRY, L.ZIPCODE
FROM VW_RPT_INV_STANDARD_FORMAT I
JOIN LOCATION L ON L.LOCATIONID=I.LOCATIONID
WHERE ' + @whereclause
EXEC
@clause
becuase when i run it i get this error now
ORA-06550: line 1, column 9:
PLS-00103: Encountered the symbol "@" when expecting one of the following:

<an identifier> <a double-quoted delimited-identifier> form
