monetdb5/extras/jaql/json.c
Branch: Jul2012
Log Message:
extract: don't insert JSON null for unmatchable search elements
nil elements typically happen as side-effect of outerjoins (when other
inputs were to be preserved in a jaql join) but extracting them as
separate null entries just causes trouble down the road because these
ghost nulls also count in counts
