Well, links don’t seem to work here for the time being. Hopefully, this URL will go through legibly, to where you can copy and paste it.

In case you haven't seen this already, here's a good article about dealing with BLOBs and CLOBs within RPG with SQL. http://www.ibmsystemsmag.com/ibmi/developer/8394p1.aspx

We are currently at v5r4 and will be going to v6r1, but I’m trying to get my head around how to read a 100MB field into an RPGSQL program. I’ve seen some examples using the BLOB locator, and I think that this is the way to do it, but I guess I need to research a little more. I appreciate all of your comments.

In 6.1 of the operating system, the RPG limits have been significantly increased, such as field sizes up to 16MB.

What release is your system on?
