Test for the existence of a record in a table

Damien McBain

Hi L&G,

How do I (with VBA) test for the existence of a certain value (or text) in a
prescribed field in a table? Like:

If (ThisText exists anywhere in ThisField of ThisTable) Then
do something
Else
do another thing
End IF

Any help appreciated.

Here's an example using the Categories table from the Northwind sample
database ...

Public Sub DoesItExist()

Dim rst As ADODB.Recordset
Dim boolFound As Boolean

Set rst = New ADODB.Recordset
With rst
.ActiveConnection = CurrentProject.Connection
.Open "SELECT Count(*) AS TheCount FROM Categories WHERE
CategoryName = 'Confections'"
boolFound = .Fields("TheCount") <> 0
.Close
End With
If boolFound Then
MsgBox "Found it"
Else
MsgBox "Didn't find it"
End If

End Sub
