Can you suggest how to get such field? I see the place in the code
where this happens, but I hardly see how can it happen. This code is
in FBLongVarCharField.getBlob():

if (rs.row[numCol]==null)
return BLOB_NULL_VALUE;

Long blobId = new Long(XSQLVAR.decodeLong(rs.row[numCol]));

At this point blobId is equal to new Long(0), which for FBBlob
implementation means "create new blob". There is either bug in FBBlob
assuming that there can be no 0 blob ID, or in long decoding
function. But say that for sure I will need some idea how to
reproduce this bug.

A test case would be great!

Thanks!
