Question

I download a db from internet. I save it in my datases folder and I open it.
Inside the db there is a table “Ads” with 6 fields. 2 of these fields are BLOB. When I want to read from this table… I have some problem… I noticed that when I read a row with a blob field more bigger than 1 mega byte, this causes an exception… “get field slot from row 0 col 0 failed”. if it’s a little blob, all is ok… thanks in advance 🙂

There’s a limit of 1MB on internal assets due to dynamic decompression; the 1MB limit also seems to apply to Cursor blobs but this doesn’t seem to be documented anywhere.

Generally you should avoid blobs in SQLite as they perform poorly; instead save the blob data as a file and store the location of the file in your DB.
