Select case with query

Question

Hello experts.
i'm in sales offer > table OQUT.
It is possible to have a FMS that select a query depending the OQUT.cardcode??
E.G.
if cardcode is A then run query A
else cardcode is B then run query B
i try this query :
SELECT CASE  $[OQUT.cardcode]
when '+MASTERFD'  Then
select a.itemcode, a.price, c.itmsgrpnam
from
     itm1 a
     inner join oitm b on a.itemcode = b.itemcode
     inner join oitb c on b.itmsgrpcod = c.itmsgrpcod
where
a.pricelist = (select listnum from ocrd where cardcode = $[OQUT.CardCode]) and
c.itmsgrpnam = $[OQUT.U_JDT_OFF_MER] and
(a.price <> 0 and a.price is not null)
for browse
else
select a.itemcode, c.itemname, a.price, a.fromdate, a.todate, d.itmsgrpnam, a.linenum
from spp1 a inner join
     (select cardcode, itemcode, max(todate) as ultimo from spp1 group by cardcode, itemcode) b
     on a.cardcode = b.cardcode and a.itemcode = b.itemcode and a.todate = b.ultimo
inner join oitm c on a.itemcode = c.itemcode
inner join oitb d on c.itmsgrpcod = d.itmsgrpcod
where a.cardcode = $[$4.0]
end

Hi Istvan...
The query run in this mode:
If  $[OQUT.cardcode]='+MASTERFD'
select a.itemcode, a.price, c.itmsgrpnam
from
     itm1 a
     inner join oitm b on a.itemcode = b.itemcode
     inner join oitb c on b.itmsgrpcod = c.itmsgrpcod
where
a.pricelist = (select listnum from ocrd where cardcode = $[OQUT.CardCode]) and
c.itmsgrpnam = $[OQUT.U_JDT_OFF_MER] and
(a.price != 0 and a.price is not null)
else
select a.itemcode, c.itemname, a.price, a.fromdate, a.todate, d.itmsgrpnam, a.linenum
from spp1 a inner join
     (select cardcode, itemcode, max(todate) as ultimo from spp1 group by cardcode, itemcode) b
     on a.cardcode = b.cardcode and a.itemcode = b.itemcode and a.todate = b.ultimo
inner join oitm c on a.itemcode = c.itemcode
inner join oitb d on c.itmsgrpcod = d.itmsgrpcod
where a.cardcode = $[OQUT.cardcode]]
Thank you a lot...
