If my object view has multiple columns in it, say cola, colb.colc, and
cold, how would I code the instead of update to distinguish between
update ov set cola null, colb = 2 where colc = 3 and cold = 4;
and
update ov set colb = 2 where colc = 3;
In other words, the new value for a column can be null because it's
being set to null or because it's omitted from the set clause (i.e.,
should NOT be changed). Similarly the search criteria may include a
varying number of conditions.
Thanks in advance
