ID: 6601 User Update by: koos@kzdoos.xs4all.nl Status: Closed Bug Type: Sybase-ct (ctlib) related Description: blobs retrieved from database are limited to 32768 nibbles Thanks, this helped! Previous Comments: --------------------------------------------------------------------------- [2000-09-27 23:58:38] andi@php.net Closed thanks to Magnus Jonsson: This is a Sybase configuration issue and not a bug. If you haven't specified TEXTSIZE in 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. --------------------------------------------------------------------------- [2000-09-07 09:23:16] koos@kzdoos.xs4all.nl 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: $fp=fopen($userfile,'r'); $blob=bin2hex(fread($fp,filesize($userfile))); $qid=sybase_query(" INSERT INTO blob(blobtype_id,title,body) VALUES ($mimetypeid,'$blobtitle',0x".$blob.")"); and retrieve them using $qid=sybase_query(" SELECT blobtype.mimetype,blob.body FROM blob,blobtype WHERE blob.blob_id=$blobobjectid AND blob.blobtype_id=blobtype.blobtype_id",$conid); if ($qid){ list($blobtype_mimetype,$blob_body)=sybase_fetch_row($qid); header("Content-Type: $blobtype_mimetype"); $bloblen=strlen($blob_body); 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 --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=6601
