Join Adam Wilbert for an in-depth discussion in this video Understanding the Totals field, part of Access 2010: Queries.
Access databases are really good at collecting and storing large amounts of raw data.…Most of the time you want to summarize or aggregate data points together to get…a better understanding of some of the trends or rankings that might otherwise be…buried within all that data.…We can create that query by going to Create tab and then Query Design.…Let's add our DirectCustomers table and close this window.…Let's add a couple of fields here, FirstName and LastName, and we'll run this query.…
We'll see that Access after brief calculation returns a thousand records.…This is the number of customers that we have in our database.…We can verify that by going into Chapter 1 and taking a look at the…DirectCustomers table.…I'll open this and we'll see that we have the same thousand records.…Go ahead and close this down.…I'll go back to our Design view in the Query.…Let's add another table.…I'll right-click and say Show Table.…Let's add our Orders table.…We'll close the Show Table window and we'll add OrderID.…
