Hi,
There are 2 kinds of aggregation functions in SQL++ right now:
1) those with the prefix ARRAY_ (which share SQL's behavior or ignoring
NULL) and
2) those with the prefix COLL_ (which return NULL, if one of the values
is NULL).
To reduce the confusion about which functions implement a strict NULL
handling I’ve renamed the COLL_ functions to use the prefix STRICT_
instead. To ease migration both prefixes are allowed right now.
But I’d like to get rid of the COLL_ prefix after the 0.9.4 release.
Would that work (could we migrate current uses of the COLL_ prefix
relatively quickly)?
Or do we know of uses of these functions that cannot easily be migrated?
Cheers,
Till
