I have a database of books that was originally created as a flat file.
Each record has a number of fields, including the authors name. I'm
trying to convert the database to something a little more efficient.
I've created a new table (called Authors) of unique authors names and
assigned each one a unique ID. I've added a new field in the original
table (called Books) for the author's ID. Now, I need to update the
original table with the author ID from the Author's table.
Something like this:
UPDATE Books SET AuthorID = Authors.AuthorID WHERE AuthorName =
Authors.AuthorName
This obviously doesn't work. Any assistance on how to forumulate this
query (or, if I'm headed down the wrong path, the correct way to do this
operation) greatly appreciated.
