Subject: Re: [sqlite] Fastest way of UPDATE'ing

I have this scenario...
6 users with local dbs
1 network db to backup all those DBs and to share info.
Every local DB unique record id based on the network DB. So, before each
user creates a new record, the tool asks the network ID for the next
available sequential record and creates a new record on the local DB
using that unique id from the network DB.
The question is, what is the fastest way to UPDATE the main DB? Right
now, what I am doing is a for each record and UPDATE all the values where
id=<uniqueID>. Is there a faster way?
Jose,
If I understand your application, I think you should be able to merge the
local databases into the network database using either an insert or
replace (if you want to replace existing records in the network DB with
potentially modified records from the local DB), or an insert or ignore
(if you want to leave the records that already exist in the network DB
alone). Since each record has an ID that is unique across the entire
network you can insert the local records into the network DB with worrying
about ID conflicts, there is no need to update records in the network DB.
If you are only storing new records in the local databases then you can
just do an insert into the network DB.
