How to create a custom field of tye blob for custom object?

James LoghryJames Loghry
There is no blob field type in Salesforce.  A couple of thoughts here.  Either you can store it as an attachment related to the record, or store it as a very large string, hope the blob doesn't exceed the size of the string, and handle any encoding / decoding through triggers, etc.
