I am far from an expert in BLOB fields but here is my understanding of them. If there are any other gurus out there I will follow with interest as it is not something I have had cause to use/do yet.
1. Being Binary Large Objects I believe a BLOB field should be able to hold a pointer to a .doc or .pdf file.
2. I don't think you can search on the BLOB field as it is only a pointer to the actuall file. I seem to remember form somewhere though that you may be able to search them if it is full text indexed. (Don't quote me on that though)
3. As the table only stores a pointer to the BLOB the length of the field doesn't change when the file changes.
Sorry can't supply any examples for using or configuring BLOB fields
I need to upload .doc files to a BLOB field.
Does anyone know a way to do this? I guess I could use plain Insert commands from SQL Query Analyzer. Alternately, I want to use VB.NET to create an interface for the user to upload this .docs and to retrieve them.
Thank you and I would appreciate some examples if possible.
