Populate a new field in an existing table

From: Dorian on 27 May 2010 16:52 Write a query to do an insert into that column for each row... Update MyTable Set [Financial Year] = "2009-10" Where [Financial Year] IS NULL; By the way, I strongly advise against using any column name with an embedded space. -- Dorian "Give someone a fish and they eat for a day; teach someone to fish and they eat for a lifetime".

The Update query Dorian suggests will work nicely, but I really question whether you're solving the wrong problem! -- John W. Vinson [MVP]
From: Dominic on 28 May 2010 09:53 Thank you for the advice guys. The information in the field isn't available elsewhere. Dorian, the query worked perfectly, and thank you for the heads up on spaces in column names. This has now been amended. Dominic "John W.
