Changeset: 708e850ffb9c for MonetDB
URL: http://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=708e850ffb9c
Modified Files:
sql/backends/monet5/rel_bin.c
Branch: Feb2013
Log Message:
DO NOT PROPAGATE fix for sample bug.
Sample call on Feb2013 does not follow the headless design, yet SQL code
generator assumed so, thus performing a leftfetchjoin on values instead of
oids. This is not fixed for Feb2013 release. There is no need to be propagated
to the default branch, since there we use the headless version and sql code
genarator is correct.
