You can use the
RecordSource property to specify the source of
the data for a form. Read/write
String.
Syntax
expression.RecordSource
expression A variable that represents a
Form
object.
Remarks
The
RecordSource property setting can be a table name, a
query name, or an SQL statement. For example, you can use the following
settings.
| Sample setting |
Description |
| Employees |
A table name specifying the Employees table as the source of
data. |
SELECT Orders!OrderDate FROM Orders; |
An SQL statement specifying the OrderDate field on the Orders table as the
source of data. You can bind a control on the form or report to the OrderDate
field in the Orders table by setting the control's
ControlSource property to
OrderDate. |
Note |
| Changing the record source of an open form or report causes an automatic
requery of the underlying data. If a form's Recordset property
is set at runtime, the form's RecordSource property is
updated. |
After you have created a form or report, you can change its source of data by
changing the
RecordSource property. The
RecordSource property is also useful if you want to create a
reusable form or report. For example, you could create a form that incorporates
a standard design, then copy the form and change the
RecordSource property to display data from a different table,
query, or SQL statement.
Limiting the number of records contained in a form's record source can
enhance performance, especially when your application is running on a network.
For example, you can set a form's
RecordSource property to an
SQL statement that returns a single record and change the form's record source
depending on criteria selected by the user.
Example
The following example sets a form's
RecordSource property to
the Customers table:
| Visual Basic for Applications |
Forms!frmCustomers.RecordSource = "Customers"
|
The next example changes a form's record source to a single record in the
Customers table, depending on the company name selected in the
cmboCompanyName combo box control. The combo box is filled by an
SQL statement that returns the customer ID (in the bound column) and the company
name. The CustomerID has a Text data type.
| Visual Basic for Applications |
Sub cmboCompanyName_AfterUpdate()
Dim strNewRecord As String
strNewRecord = "SELECT * FROM Customers " _
& " WHERE CustomerID = '" _
& Me!cmboCompanyName.Value & "'"
Me.RecordSource = strNewRecord
End Sub
