DCount By Richard Rost 
4 years ago
Count Records in a Table or Query with Criteria In this video, I will show you how to count up values from a table or query. We will count up the total number of orders that a customer has and display them on the customer form. Roberto from Silver City, New Mexico (a Gold Member) asks: I'd like to be able to quickly see the total number of orders that a customer has when I open up their record in the customer form. Right now, I have to open up the order form and look at the number on the bottom. This would save me a lot of time. MembersMembers will see how to use DCount to limit the number of records in a related table (such as in a subform). This would be handy to, for example, set a maximum number of students per class, or a minimum number of items per order. We'll also see how to refresh a parent form when a child form is closed, and put that order count in the button caption. We'll also discuss why you should not use D-functions in queries (use aggregate queries instead).
