Join Adam Wilbert for an in-depth discussion in this video Exploring the Expression Builder interface, part of Access 2010: Queries.
In the last movie, we saw that the Query Design Wizard used a function to…calculate the count to the number of records within our query.…You can see that here.…I currently got the qry_ OrderHistory query open in Design view.…In the very end here, I got the Count function.…Let me right click in this field and I'll say Zoom to open it up in the Zoom box.…So the way that Access's wizard created this counting field is it used a…function called Count.…Now functions are always written with the same formatting.…
You have the name of the function and then in parentheses wrap whatever you want…to apply that function to.…So we had a count function that's counting everything with the asterisk wildcard.…We also see that Access's wizard provided us with an alias.…Count Of tbl_Products:.…So let's take a look at how we can apply functions to our database.…We'll go ahead and say OK to close the Zoom box.…Let's go ahead and close this query.…We don't need to save it.…I'll create a new query in Design view.…We'll add a couple of tables here.…
