I found this article after thinking up two possible solutions. I was trying to chunk the blob into multiple rows of 1 record set, but doing multiple queries with SUBSTRING() is just as good, I guess. This article helped confirm my suspicions, and it explained the different settings required for the server and the client.

I certainly would not recommend this in a shared hosting enviroment. To me it does not sound beneficial for you to do that and I would avoid doing so, simply hold pointers to the file.

Anyway hope that helps.

Thanks for the insight! I just started with a company that is trying to get their Web site in order. The previous Web guy built the product admin tool to store images and PDFs in the mySQL db.

Seemed to work, sometimes slowly. This is on a shared hosting account running ???. The db was NEVER backed up, My second day on the job, i had been searching locally to find the non-existant backups and at that very moment, the table where the images were stored became corrupt. Lost everything. The host couldn’t restore it…. up the creek, so to speak.

I immediately uploaded all (i hope) relevant images to a directory, and patched his code to look directly at the images based on the product #s. YIKES!

Of course i lost all info from that table, including thumbnails, keys, sizes, alt text….

So now. Do i try to replace everything back into the DB in a new table? Do i go with what i know and create pointers the the files instead? Storing BLOBS fits the current structure, but i’ve never had much faith in doing that. Doing it with pointers means i start from scratch… grrrr!
