CONCAT on BLOB

2003-12-02 Thread Jim Kutter
Hi folks.

I'm storing files in a BLOB table for a number of reasons for my web
app, and I'm trying to break up uploads so I insert smaller chunks (my
app imposes restrictions on memory usage, so reading the whole file at
once and doing an insert doesn't work).

What I do is insert the record, then call a series of UPDATE queries on
the record concating the new chunk with the existing blob column.

The problem I'm having is that the size of the blob column is WAY off
for larger files (2MB or so). My app reports that the entire file was
read properly, but not all of it was inserted properly into the DB.

Any ideas on why this is happening? Any suggestions for alternatives?
Storing the files on the filesystem is not an option for me.

Thanks

I'm using 3.23.36 (linux RedHat) with MyISAM tables.
