  invisible(dbGetQuery(theDb, "PRAGMA busy_timeout = 86400")) # recommended

  # try to find "taskOne" task id for any model
  taskId <- getTaskIdByName(theDb, taskName = "taskOne")
  if (taskId <= 0L) warning("task not found: ", "taskOne")
  
  # get model by name: use such call if you have only one version of the model
  defRs <- getModel(theDb, "modelOne")

  # try to find "taskOne" task id for "modelOne"
  taskId <- getTaskIdByName(theDb, defRs, "taskOne")
  if (taskId <= 0L) warning("task not found: ", "taskOne")
