DCount

Using the DCOUNT Function

In this tutorial you will learn how to use the DCOUNT Function.

Take an example Table of Customers.

2JoeSmith716555343401/03/19905005True

9PeteSmith564559777704/04/20005003False
10BarbraPeters829282728831/12/2005501True
11JoeJones549546546601/06/20045003True
14PezzDispo26/09/201204True
16BobSmith04/10/201209True

In this example we want to find out how many Customers have a Credit Limit equal to 50 so we set the Field to * to choose any/all Fields in the Table, the Domain is CustomerT as this is the Table we are searching and the Criteria of "CreditLimit=50" as this is the Field name we are searching on.

The DCOUNT function returns an integer from a specified set of records (or domain) containing the number of records in that search.

=DCOUNT(Field, Domain, Criteria)

Query

The results using a Query would be

```	SELECT * FROM CustomerT WHERE CreditLimit = 50
```

FORM

In a Form you could set the Default Value of a Textbox to

```	=DCount("*", "CustomerT", "CreditLimit=50")
```
VBA

In a Form add a TEXTBOX control and rename it "txtDCount", then you could add the following in the Load Event.

```	Private Sub Form_Load()
txtDCount = DCount("*", "CustomerT", "CreditLimit=50")
End Sub
```
