I think he has more or less abandoned that project. So I've had to tweak
the ODBC driver to work with
blobs anyway (because the 0.65 ODBC driver could only handle text).
I've tweaked the SQLGetData to retrieve a blob correctly, haven't tried it
yet with large data tho.. but
not SQLPutData yet (at least not sufficiently). So you mean I'd alloc a
buffer in SQLBindParameter
(where length of data is given), then fill that buffer in SQLPutData (til
its done), and then pass it to SQLite?

Subject: [sqlite] Writing/reading blobs
Hi all,
I'm using SQLite3 via the SQLite ODBC wrapper. Amongst other
things I need
to store large blobs. When using ODBC this means several calls to
SQLPutData/SQLGetData. I've read the docs and it seems that
SQLite doesn't
support this. Is this in planning, and/or can someone well
versed in the
code of SQLite say if this is doable?
This is a question to ask the author of the ODBC driver. Faking
SQLGetData()'s stream-like fetch is easy, but it's a little hard to fake
SQLPutData(). SQLite expects the entire blob to be assigned or
fetched. If
you're working with massive blobs, be aware SQLite retrieves them from
disk
in their entirety so you need to have to enough RAM to hold an entire
row of
such a table.
