Domain Aggregate functions such as DCount, DLookup, DMax etc have no direct equivalent in Base.
Operands in expr can include the name of a table field or function(which can be either intrinsic or user-defined butnot other SQL aggregate functions).
If you apply aggregate functions to all the fields in a query, you do not have to create the GROUP BY clause.

You use totals queries and aggregate functions only when you need to find data that falls into a set of groups or categories.
You should, therefore, consider the possibility that some of your reportsmight not contain any detail records and that aggregate functions, such as the Count function, might have nothing to count.
In addition to aggregate functions, Access also provides"domain" aggregate functions that you use to sum or count values selectively.
A totals query is a select query that uses aggregate functions such as Min, Max, Sum, First, and Last to calculate values for a given field.
Whenever you use aggregate functions or queries that return ambiguous or duplicate Field object names, you must use the AS clause to provide an alternate name for the Field object.
A totals query is a select query that uses aggregate functions such as Min, Max, Sum, First, and Last to calculate values for a given field.
The AGGREGATE function can apply different aggregate functions to a list or database with the option to ignore hidden rows and error values.
