Can some problem exist when creating 2 indexes of the same records? CREATE UNIQUE INDEX FK_SCEMMES_A ON SCEMMES (IDAC,IDREG,NUMC); CREATE UNIQUE DESCENDING INDEX FK_SCEMMES_D ON SCEMMES (IDAC,IDREG,NUMC);
I make it because I need values max select max(m.numc) as numc from scemmes m where ((m.idac=1) and (m.idreg=1)) Best Regards ========= || ISMAEL || ========= [Non-text portions of this message have been removed]
