Application.DLast Method

Access Developer Reference

You can use the DLast function to return a random record from a particular field in a table or query when you simply need any value from that field. .


expression.DLast(Expr, Domain, Criteria)

expression   A variable that represents an Application object.


Name Required/Optional Data Type Description
Expr Required String An expression that identifies the field from which you want to find the first or last value. It can be either a string expression identifying a field in a table or query, or an expression that performs a 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 Required String A string expression identifying the set of records that constitutes the domain.
Criteria Optional Variant An optional string expression used to restrict the range of data on which the DLast function is performed. For example, criteria is often equivalent to the WHERE clause in an SQL expression, without the wrd WHERE. If criteria is omitted, the DLast function evaluates expr against the entire domain. Any field that is included in criteria must also be a field in domain; otherwise, the DLast function returns a Null.

Return Value

If you want to return the first or last record in a set of records (a domain), you should create a query sorted as either ascending or descending and set the TopValues property to 1. From Visual Basic, you can also create an ADO Recordset object and use the MoveFirst or MoveLast method to return the first or last record in a set of records.
