Changeset: e33b10c72850 for MonetDB
URL: http://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=e33b10c72850
Modified Files:
gdk/gdk_sample.c
Branch: default
Log Message:
Set nil properties correctly.
We only *know* that there are nils if the column is VOID/NIL. If the
source column has nils doesn't mean the sample has them.
