*where irseq >= :#crfrnseqp and irpgm = case when
:#crfrpgms = ' ' then irpgm else :#crfrpgms end*

select;
when #crfripos = 'S';
exec sql // Declara o Cursor
declare c_tcinrely_S scroll Cursor for
Select irseq, irdseq, irdlsq, irpgm, iravis, tcirvins, irdatu,
irhoru
From manastacio/tcinrely


*where irseq >= :#crfrnseqp and irpgm = case when
:#crfrpgms = ' ' then irpgm else :#crfrpgms end Order By irseq,
irdseq;*
exec sql // Abre o Cursor
open c_tcinrely_S;
exec sql // Consulta a Informação

fetch next from c_tcinrely_S for :wnnreg rows into :wsele;
when #crfripos = 'N';
exec sql // Declara o Cursor
declare c_tcinrely_N scroll Cursor for
Select irseq, irdseq, irdlsq, irpgm, iravis, tcirvins, irdatu,

Subject: SQL ignore part of WHERE if parameter is null

select * from ncnotl
where ncnlnorn = :wnnorn and ncnldtpco = :wndtpco

anyone now if its possible to ignore this - ncnlnorn = :wnnorn - when
the field has no information and pass to the other condition.
