Re: Redbooks / Redpapers for i

Inspired by another thread, I went to redbooks.ibm.com and searched
i-related publications using:
"Power i" OR RPG OR iSeries OR "AS/400"

Sorting by date, I was a bit surprised and disappointed by the fact that
the most recent publication dates back to 2010. Is there a term in my
search that I've missed?

I was hoping to see an updated version of "Who Knew You Could Do That with
RPG IV? A Sorcerer's Guide..." which was published a full 15 years ago.
(In fact, wasn't there talk about updating that one awhile back?)

I was also hoping I'd find an SQL "cookbook" specific to i. Some kind of
"Who Knew You Could Do That" book for SQL on i. The stuff I've learned on
this list in the past few months certainly only scratches the surface of
what's possible, so it would be useful to see what I'm missing.
