Simple Database Question

[AdrianD]

Good day,

I used the peq daily dump provided by cavedude in a very recent new install. I have begun to make simple alterations to the database in areas such as npc_type, spawnentry, loottables, etc. If I update the database with the daily dump in the future, will I lose the alterations I made?

EDIT:
Is there a way to make blanket changes to mob hp/damage? For example, increasing all mob hp by 4 per level no matter the mob type. Or is working with the database in this manner just going to be extremely tedious?

I'm green to all this but I'm having a blast customizing all this stuff. I see a vacation in my future...
