[gdal-dev] Corrupted geopackage

[Rahkonen Jukka (MML)]

Hi,

And when you .dump https://www.sqlitetutorial.net/sqlite-dump/ the damaged table into a text file, do you only get 78 insert entries into it?

Thanks for your suggestion, Jukka! I tried all the advice from stackoverflow. I can do ".recover", but get only the features that have been visible all along.
In the original .gpkg, I cannot DROP the affected RTree-Index. It gives me the same disk malformed error. But that would also have been my initial idea...

Hi,

Without being able to see your database it is hard to give more advice that https://stackoverflow.com/questions/18259692/how-to-recover-a-corrupt-sqlite3-database/18260642 gives. Did you try all of them? Because the problem has something to do with the spatial index I would have a try be dropping it and repeating the suggested tricks.

Aihe: [gdal-dev] Corrupted geopackage

Hi everyone,

I've a problem with a corrupted geopackage.
It should contain a table with 694 entries, but only 78 are visible when opening the file with DB Browser for SQLite or QGIS. The table gpkg_ogr_contents says 694 though. When opening the .gpkg with a Notepad or similar, I can see that there are more than 78 entries.

The error message in DB Browser is "database disk image is malformed in "PRAGMA "main".TABLE_INFO("rtree_XXX");" So it seems that there is a problem with the index of the concerned table.

Does anyone know how to fix this? I tried  https://stackoverflow.com/questions/18259692/how-to-recover-a-corrupt-sqlite3-database/18260642 but without success.

Thanks in advance for your help!
Isabel
