Good afetrnon,

i stumbled with this senetence but i cant get it at all, its just comparing 2 NULL VALUES? (but how can a null value can be greather (>) than another NULL value?)

AND (ISNULL (TEMP.FEC_REAL,''19000101'') > ISNULL (ACA_INCIDENCIA.FEC_REAL,''19000101'')

OR ISNULL (TEMP.FEC_HISTORICO,''19000101'') > ISNULL(ACA_INCIDENCIA.FEC_HISTORICO,''19000101'')

Thanks for your help
