Similarly to deleting tables, if you have ever needed to delete all the queries from a database, it can be a long tedious task as Access does not allow multiple Object selection. So you have to delete each query, one by one!!! Hence, why I created the simple little procedure below.

'---------------------------------------------------------------------------------------
' Procedure : DeleteAllQueries
' Author    : Daniel Pineault, CARDA Consultants Inc.
' Website   : http://www.cardaconsultants.com
' Purpose   : Deletes all the queries from the active database

Function DeleteAllQueries()

    Dim db               As DAO.Database
    Dim qdf              As DAO.QueryDef

    DoCmd.SetWarnings False
    Set db = CurrentDb
    For Each qdf In db.QueryDefs
        DoCmd.DeleteObject acQuery, qdf.Name
    Next

Error_Handler_Exit:
    DoCmd.SetWarnings True
    Set qdf = Nothing
    Set db = Nothing
    Exit Function
Error_Handler:
    MsgBox "The following error has occurred" & vbCrLf & vbCrLf & _
           "Error Number: " & Err.Number & vbCrLf & _
           "Error Source: DeleteAllQueries" & vbCrLf & _
           "Error Description: " & Err.Description, _
           vbCritical, "An Error has Occurred!"
    Resume Error_Handler_Exit
End Function
