How to speed UPDATES

[Etienne Orliac]

Dear all,

 I have to update 1500 lines on a daily basis in a single table. My problem is that it
takes a while to execute. All the updates are siimilar.

 I've read that you can delay the updates and just execute once or something like that.
However, I wasn't able to find any documentation about it.

 So I would greatly appreciate some help.

 Thanks a lot,

Etienne.
