actually, all the rows have both 'debit' and 'credit', but based on=20
the hint you gave i made this query which works:

select
sum(case when debit=3Daccount then amount else 0 end) as debtotal,
sum(case when credit=3Daccount then amount else 0 end) as credtotal
from voucherrows
where
debit =3D account
or=20
credit =3D account

thanks for taking the trouble - i never believed this was possible,=20
just asked on the off chance that it *may* be possible
=2D-=20
