This is probably a simple question, but I really don't know what I'm doing in Excel, so hopefully someone can help me out.
I've been given an Excel spreadsheet that has two relevant columns to my task. The first column is an "External ID", and the second column is an "Internal ID". I need to select a bunch of data out of our databases (with various joins) using the Internal ID as the key, but then all of this data needs to be linked back to the External ID, and the only link between Internal/External is this spreadsheet.
For example, say a row of the spreadsheet looks like this:
ExtID IntID
AB1234 2
I need to select all the data relevant to the item with ID #2 in our database, but I have no way to get "AB1234" from the database, so I need to somehow relate this data back to "AB1234" using the spreadsheet.
What's the easiest way to accomplish this? The version of Excel is Excel 2007, and the database is Oracle, if that's relevant.
Note that I only have read permission to the production databases, so creating tables and importing the spreadsheet data to do a join is not an option.
