Hi
I have two tables named [Sites and Weekly Averages] and [Average Groupings].
In both tables there is a field named [Site Serial] with unique values, but they are not related as yet. I want to update a field in [Sites and Weekly Average] with the values from a field in [Average Groupings] where the [Site Serial] values match.
I am new to SQL but I think this would be an UPDATE query? Can someone help me with constructing a query.
Many thanks
James
