Actually, assuming that my_update_query is the name of a stored query, I
believe you need to use:
Dim qdfUpdate As DAO.QueryDef
Set qdfUpdate = CurrentDb.QueryDefs("my_update_query")
qdfUpdate.Execute dbFailOnError
If you knew the SQL of that update query, then you could use the Execute
method on the Database object.
