I've a bunch of IDs fetched(around 60,000) from a DB. I'm using these IDs to fetch data from another DB having a related fields in its tables. I'm using IN clause for it. i.e. for e.g. SELECT * FROM site_users WHERE parentUserId IN (1,2,3,4....)
Again here parentUserId is Indexed. The query is running fine for now. I wanted to know how MySQL interprets and executes this query and can it have problems in future if number exceeds 60,000?? __________________________________ Do you Yahoo!?
