Hi,
you can try modify your logic by adding IMPORT_ID to that table
and then you can import data without need to delete in the same time.
Then you can delete data in some portions during a day.
and successively run
SELECT COUNT(*)
An update and a huge thank you to everyone for your input and help on this. I
spent most of yesterday writing Linux bash scripts and closing off ports on the
database server so I could run this from a remote SSH request from a web
server. I wrote a pretty extensive script library that will

Btw, truncate was predicted for Firebird 3, but something seems to be
delaying its implementation :-(
I hope it will be available for FB 4, and even better if it can

Also one further question Do later versions of Firebird (ie. 3 or 4) have
any performance increase for cooperative garbage collection at all? Would I
expect to see any performance improvement by any newer version, or different

Thank you for the detailed reply, Helen. I can definitely execute a script to
drop all dependencies and then drop the table, and then rebuild them back in
via a CLI Linux script. I thought that was pretty extreme, but if this is the
