When I want to add the blob objects back to mysql after the data was
imported,
mysqlupdate ilwdtypes set type_blob=load_file('./lwdtypes.del.001.lob');
>
I ended up having the entire blob in each row of the column
mysqlselect hex(type_blob) from ilwdtypes where type_char_s =
"1216412567";

How can I get mysql to update each blob properly to match the ones in db2 ?

db2 version 9.1.5 on 32 bit Linux
mysql on 32 bit linux Server version: 5.0.45 Source distribution

Thanks.

I found one solution :
I have to split up the lob file from db2 using the offset and size of
each lob into individual files and update each of the rows with the
split load file.
Tedious but works.
