Re: Copy BLOB to IFS

I could swear I've seen something built into the OS for this...

A bit of googling turned up
http://www.ibmsystemsmag.com/ibmi/developer/general/BLOBs,-CLOBs-and-RPG/?page=2

1. Use the SQL CAST function to retrieve the data into an "ordinary" RPG
field
2. Bring the CLOB contents into a data structure using special CLOB
support
3. Access the CLOB contents via a LOB Locator
4. Access the CLOB contents via an IFS file using a file reference

Of course the article only covers 1-3....

So Jon...what's the deal with option #4? :)

Seems like it may be something we will see in the future. It appears that
mainframe DB2 handles it via EXPORT.

db2 export to myfile.del of del lobs to mylobs/
lobfile lobs1 modified by lobsinfile

Not sure, I did a program that read an image (to IFS) and stores in a

blob, Probably is easy to revert, I forgot the details, but it is very
likely you can find them searching for blob_file.

D blob s sqltype ( blob_file)

RPG or sql preprosesor creates a data structure with blob_nl, blob_name,

blob_dl, blob_fo where you load the ifs name, the name length, the data
length, etc.

Yes, you have to take the blob data and write it out as an IFS file.
Unless someone has any detail on a function to do this?
