Overview

I ran: semsql make doid.db, and when I examined the tables, everything except the following tables were empty:

  1. prefix
  2. sqlite_master

I don't think these two tables are specific to the ontology either; I think they are the same for every DB I would create, based on some kind of semsql templating.

Replicating this issue

  1. Have semsql
  2. Download and unzip doid.owl.zip
  3. Run semsql make doid.db from unzipped directory.

Additional information

Version: 0.1.7: Using this version because I'm not currently able to use the next highest version, 0.2.0. Edit: I also tried 0.2.0 and this happens for that version as well.

@matentzn FYI

That's very unusual

Just to be completely sure, can you report the results of this:

sqlite3 mirror/doid.db -cmd "SELECT COUNT(*) FROM statements;"
joeflack4 commented 2 years ago

@cmungall My bad. I'm new to this PyCharm DB browser. It seems that, even after I deleted .template.db, that is the DB that was still somehow opening up when I was double clicking doid.db. The 0 results were consistent with nothing coming back from .entities() (under earlier circumstances), so I felt as if the DB browser was corroborating.

It seems I'm good now.
