Re: Identity Columns

Also an unsuccesful write - for example when a constraint prevented the
record to be written - will result in the loss of the provided identity
value. It will not be used for the next write.

One thing I did notice that I mentioned before is I can see that ID's
are
skipped. I guess this could be caused by me creating / deleting /
creating
records causing a gap in the IDs but I'm also not sure if it has
anything
to do with ID caching ( which I don't specify in my DDL. I think the
default is not to cache. )


The default *is* no cache but if you are deleting records and
inserting new records then you will definitely see a gap. The database
remembers the last identity it used -- not the last identity in the table.
