While reading the apple documentation someone pointed me to I found
this quote:
SnapshottingWhen Enterprise Objects fetches data, it records the
state of the fetched database row in a snapshot. The information in a
snapshot is used to support Enterprise Objects optimistic locking
mechanism. It is also used when changes are committed back to a data
source to update only the attributes that were changed since the last
fetch."
I was thinking that I could just use LastModDate to tell me if a row
has changed as thus modeled only that attribute for the optimistic
lock flag. Does this mean that if someone edits a different text
attribute that it won't get written to the database? Will only the
LastModDate get updated in the generated SQL because is was flagged
with the optimistic lock icon in EOModeler?
Thanks
James
