Recordset.NoMatch Property (DAO)
Indicates whether a particular record was found by using the Seek method or one of the Find methods (Microsoft Access workspaces only).
Syntax
expression .NoMatch
expression A variable that represents a Recordset object.
Remarks
When you open or create a Recordset object, its NoMatch property is set to False.
To locate a record, use the Seek method on a table-type Recordset object or one of the Find methods on a dynaset- or snapshot-type Recordset object. Check the NoMatch property setting to see whether the record was found.
If the Seek or Find method is unsuccessful and the NoMatch property is True, the current record will no longer be valid. Be sure to obtain the current record's bookmark before using the Seek method or a Find method if you'll need to return to that record.
Note
Using any of the Move methods on a Recordset object won't affect its NoMatch property setting.
Example
This example uses the NoMatch property to determine whether a Seek and a FindFirst were successful, and if not, to give appropriate feedback. The SeekMatch and FindMatch procedures are required for this procedure to run.
Sub NoMatchX()
Dim dbsNorthwind As Database
Dim rstProducts As Recordset
Dim rstCustomers As Recordset
Dim strMessage As String
Dim strSeek As String
Dim strCountry As String
Dim varBookmark As Variant
Set dbsNorthwind = OpenDatabase("Northwind.mdb")
' Default is dbOpenTable; required if Index property will
' be used.
Set rstProducts = dbsNorthwind.OpenRecordset("Products")
With rstProducts
.Index = "PrimaryKey"
Do While True
' Show current record information; ask user for
' input.
strMessage = "NoMatch with Seek method" & vbCr & _
"Product ID: " & !ProductID & vbCr & _
"Product Name: " & !ProductName & vbCr & _
"NoMatch = " & .NoMatch & vbCr & vbCr & _
"Enter a product ID."
strSeek = InputBox(strMessage)
If strSeek = "" Then Exit Do
' Call procedure that seeks for a record based on
' the ID number supplied by the user.
SeekMatch rstProducts, Val(strSeek)
Loop
.Close
End With
Set rstCustomers = dbsNorthwind.OpenRecordset( _
"SELECT CompanyName, Country FROM Customers " & _
"ORDER BY CompanyName", dbOpenSnapshot)
With rstCustomers
Do While True
' Show current record information; ask user for
' input.
strMessage = "NoMatch with FindFirst method" & _
vbCr & "Customer Name: " & !CompanyName & _
vbCr & "Country: " & !Country & vbCr & _
"NoMatch = " & .NoMatch & vbCr & vbCr & _
"Enter country on which to search."
strCountry = Trim(InputBox(strMessage))
If strCountry = "" Then Exit Do
' Call procedure that finds a record based on
' the country name supplied by the user.
FindMatch rstCustomers, _
"Country = '" & strCountry & "'"
Loop
.Close
End With
dbsNorthwind.Close
End Sub
Sub SeekMatch(rstTemp As Recordset, _
intSeek As Integer)
Dim varBookmark As Variant
Dim strMessage As String
With rstTemp
' Store current record location.
varBookmark = .Bookmark
.Seek "=", intSeek
' If Seek method fails, notify user and return to the
' last current record.
If .NoMatch Then
strMessage = _
"Not found! Returning to current record." & _
vbCr & vbCr & "NoMatch = " & .NoMatch
MsgBox strMessage
.Bookmark = varBookmark
End If
End With
End Sub
Sub FindMatch(rstTemp As Recordset, _
strFind As String)
Dim varBookmark As Variant
Dim strMessage As String
With rstTemp
' Store current record location.
varBookmark = .Bookmark
.FindFirst strFind
' If Find method fails, notify user and return to the
' last current record.
If .NoMatch Then
strMessage = _
"Not found! Returning to current record." & _
vbCr & vbCr & "NoMatch = " & .NoMatch
MsgBox strMessage
.Bookmark = varBookmark
End If
End With
End Sub
The following example shows how to use the Seek method to find a record in a linked table.
