Maybe it's a little dumb, but i'm just not sure what is better. If i have to check about 30k rows in db for existanse, what i'd do?

#1 - one query

select id from table1 where name in (smth1,smth2...{till 30k})

#2 - many queries

select id from table1 where name=smth1

Though, perfomance is not the goal, i don't want to go down with mysql either ;) Maybe, any other solutions will be more suitable... Thanks.
