The PK assignment from the cache happens during saveChanges(). IIRC, it if runs out it will cache another batch. I could see this potentially being "dangerous" ( not deadly or anything ) if you don't end up using all your primary keys ( at least with Orcale sequences ) in that you would ask for 100 new PK's, the sequence is incremented 100 times, you only use 50 of them and you would have a missing 50 values from your PK coloum. Anyways just a random though. Yes, it will create gaps in the PK sequence. That is the price to be paid for caching. I was discussing this with Mike earlier and it appears that our code may have a nasty race condition in it. SELECT UNIQUE might not be working as we had assumed. I have not gotten around to testing it yet. The solution in the plugin that Mike just posted about is (a) safe from this race condition, (b) less wasteful of key values, and (c) overall easier to use. We were too short sighted to consider doing it at the plugin level when we wrote that PK key caching code. Chuck On 30/10/2007, at 3:52 PM, Chuck Hill wrote: Short answer: yes.

Re: Are Batch Sequences Possible ?
I'm not sure what Mike did for his. OK, I committed a fix to the FrontBasePlugin that adds batch key generation ... Right now it just does batches of 10, but it can be tweaked pretty easily. I'm using the syntax of: values (select unique from YourTable, select unique from YourTable, select unique from YourTable, ...) which is how Geert recommended that this be addressed. I suspect I could do WAY more than 10 as FB seems to just not care how big of a query you throw at it, but oh well .. 10x faster isn't bad either. ms ___ Do not post admin requests to the list.

Re: Are Batch Sequences Possible ?
Actually, I proposed an idea to FrontBase a while back, but totally
forgot to revisit this once they open sourced the plugin. The method
you want to look at is in the plugin:
public NSArray newPrimaryKeys(int i, EOEntity eoentity, JDBCChannel
jdbcchannel) {
Notice it takes an int? That int is the number of keys it needs. If
you extend the plugin, you can provide a more optimal implementation
than just a for loop (which is what most of them do in here).

Are Batch Sequences Possible ?
Hi All,
Im currently developing an app against a Oracle databas, which uses
sequence for generating its Primary Keys.
Is there a way to get WO to request a batch of sequences instead of
doing it one at a time ( which is what it appears to be doing when
you output the SQL ). For example I am doing 1 save to the database
that is inserting 142 rows into 1 table, 142 into a second and 711
into a third. Each of the 142 row table inserts takes 2 seconds to
return all of the sequence while the 711 inserts take's 8 seconds to
get the sequences. Thats 12 seconds used before it even starts the
INSERT statements, which take another 2, 2 and 8 respectively.
Meaning the total save time is 24 seconds ( with SQL debugging turned
on, its a little quicker with it turned off ).
Please someone tell me Im doing something dumb, or that there is a
better way.
