I need an MySQL Skript which does the following:

delete chunks of the database until it has deleted all link_id's greater then 10000

exmaple:

x = 10000
DELETE FROM pligg_links WHERE link_id > x and link_id < x+10000
x = x + 10000
...

So it would delete

DELETE FROM pligg_links WHERE link_id > 10000 and link_id < 20000

then

DELETE FROM pligg_links WHERE link_id > 20000 and link_id < 30000

until all id's less then 10000 have been removed

I need this because the database is very very big (more then a gig)

thank in advance
