error: no; dataset in memory has changed since last saved

use {filename}
no; dataset in memory has changed since last saved

I am just beginning to learn Stata and now facing the above issue. I am trying to open >2 different datafiles in one do-file and the error appeared. Is there a way to solve this? I have saved both datasets in the same working directory so the path should be right.

Solution

  • You need to clear before you can use a new dataset that hasn't been saved.

    If the datasets need to be joined, that is a task for append or merge. If they are separate, you can't open them at the same time. You could open two instances of Stata.

    So, a deeper answer depends on what the datasets are and why you want to look at them at the same time.
