On a membership database, I have all the info regarding all the members. I have a specific list (.csv file) of 1200 members (membership codes) and would like to select all the data regarding these (and only these) members.
I am working on R, with SQL (dbGetQuery). If my list was short I would do a selection in which the membership code must be IN (... list of codes ...), but with such a big list I don't think this is a possibility. I'm not an administrator, so I can only make queries on the database.
Any idea on how to do that?
Thanks in advance!
