Application.DMin (Access)

You can use the DMin function to determine the minimum value in a specified set of records (a domain).

For example, you could use the DMin function in calculated controls on a report to display the smallest order amount for a particular customer. Or you could use the DMin function in a query expression to display all orders with a discount greater than the minimum possible discount. The DMin function returns the minimum values that satisfy criteria. If expr identifies numeric data, the DMin function returns numeric values. If expr identifies string data, they return the string that is first or last alphabetically. The DMin function ignores Null values in the field referenced by expr. However, if no record satisfies criteria, or if domain contains no records, the DMin function returns a Null. You can use the DMin function to specify criteria in the Criteria row of a query, in a calculated field expression in a query, or in the Update To row of an update query.

DMin (Expr, Domain, Criteria)

Dim curX As Currency 
Dim curY As Currency 
 
curX = DMin("[Freight]", "Orders", "[ShipCountry] = 'UK'") 
curY = DMax("[Freight]", "Orders", "[ShipCountry] = 'UK'")

Arguments

The following arguments are required:

Expr (String) - An expression that identifies the field for which you want to find the minimum or maximum value. It can be a string expression identifying a field in a table or query, or it can be an expression that performs calculation on data in that field. In expr, you can include the name of a field in a table, a control on a form, a constant, or a function. If expr includes a function, it can be either built-in or user-defined, but not another domain aggregate or SQL aggregate function.

Domain (String) - A string expression identifying the set of records that constitutes the domain. It can be a table name or a query name for a query that does not require a parameter.

Optional arguments

The following argument is optional

Criteria (String) - An optional string expression used to restrict the range of data on which the DMin function is performed. For example, criteria is often equivalent to the WHERE clause in an SQL expression, without the word WHERE. If criteria is omitted, the DMin function evaluates expr against the entire domain. Any field that is included in criteria must also be a field in domain; otherwise, the DMin function returns a Null.
