I store blobs in sybase IMAGE fields and when I retrieve them I only get the first 32768 nibbles and nothing more.

I store them using:

     INSERT INTO blob(blobtype_id,title,body)
     VALUES ($mimetypeid,'$blobtitle',0x".$blob.")");

and retrieve them using

    SELECT blobtype.mimetype,blob.body
    FROM blob,blobtype
    WHERE blob.blob_id=$blobobjectid
    AND blob.blobtype_id=blobtype.blobtype_id",$conid);
if ($qid){
    header("Content-Type: $blobtype_mimetype");
    echo pack("H".$bloblen,$blob_body);

using debug statements I found that $bloblen is never more then 32768, and the database contains bigger datalength's.

32768 is a round number so I guess I ran into some buffer size. What to do and how to get the bigger blobs.

PHP 4.0.2, apache 3.0.12
./configure --with-mysql --with-sybase-ct=/opt/sybase --with-apache=../apache_1.3.12 --enable-track-vars

Closed thanks to Magnus Jonsson:

This is a Sybase configuration issue and not a bug. If you haven't specified
the Sybase Configuration the default is set to 32k. If you want to use
larger text or 
image fields change you Sybase Configuration or Use "SET TEXTSIZE (your
limit in bytes)" 
query to set this param before doing a query.
