Selectステートメントを実行し、その結果(1つの値を持つ1つのレコードのみ)を変数に入れたいです。
これはアクセス中のVBAコードにあります。
Private Sub Child_Click()
Dim Childnummer As Integer
Dim childnaam As String
Childnummer = Me.Keuzelijst21.Value
DoCmd.Close
DoCmd.OpenForm "submenurubrieken", acNormal, , " rubrieknummer = " & Childnummer & ""
childnaam = rubrieknaamSQL(Childnummer)
Forms!submenurubrieken.Tv_rubrieknaam.Value = childnaam
End Sub
Public Function rubrieknaamSQL(Child As Integer)
Dim rst As DAO.Recordset
Dim strSQL As String
strSQL = "SELECT rubrieknaam FROM dbo_tbl_rubriek where rubrieknummer = " & Child & ""
Set rst = CurrentDb.OpenRecordset(strSQL)
End Function
関数にRecordsetから値を返させるだけです:
Public Function rubrieknaamSQL(Child As Integer)
Dim rst As DAO.Recordset
Dim strSQL As String
strSQL = "SELECT rubrieknaam FROM dbo_tbl_rubriek where rubrieknummer = " & Child & ""
Set rst = CurrentDb.OpenRecordset(strSQL)
' new code:
rubrieknaamSQL = rst!rubrieknaam
rst.Close
Set rst = Nothing
End Function
