Question

I have a png file that is to be stored in a database, however, even when passing a length to sqlite3_bind_blob() it stops filling in the value at the first nul character.

Here’s the code in question:

fseek(file,0xC,SEEK_CUR); // Skip to 12 (0xC) and read everything (It's a raw png file)
char content[size-0xC];
fread(content,1,size-0xC,file);

sqlite3_bind_int(inserticonstmt,1,id);
sqlite3_bind_blob(inserticonstmt,2,content,size-0xC,SQLITE_STATIC);
sqlite3_step(inserticonstmt);
sqlite3_clear_bindings(inserticonstmt);
sqlite3_reset(inserticonstmt);

Any ideas?

Edit: It looks like, while the database is in fact storing the whole blob, it’s not returning it from the CLI interface

Answer 1

The sqlite cli interface has a bug where it parses blobs as strings and stops printing them early, including if it’s told to send output to a file.
