Hi, I have a list of IDs on a data frame and I want to extract information for those IDs from an external database.
I did a workaround using the "IN" clause in SQL but when the number of IDs is big this method doesn't work. In other words, I want to create a join between a local and a external table using either RODBC() or any other package. Thanks a lot for your help!
