Re: RPG SQL and Cursors

A little off-topic...

Some years ago Tracy Kidder wrote a wonderful book, "The Soul of a New
Machine", regarding the efforts of Data General's computer engineers in
building of their first minicomputers. In that chronicle, of of the
engineers charged with writing the computer's microcode got tired of working
with oscilloscopes and nanoseconds and, I quote,

*"He went away from the basement and left this note on his terminal: "I'm
going to a commune in Vermont and will deal with no unit of time shorter
than a season." "*


Dieter, believe me, I really understand and share your sentiments...

I use a balance of RLA and SQL. Usually use RLA by default and only go

to

SQL when it is a better fit (i.e. dynamic sorts, searches, ranges, etc).
We
are actively moving our web development (i.e. OpenRPGUI.com) from our

V5R3

server to our V6R1 server so I am planning on jumping into free form
embedded SQL, and on that note...

Are there any well documented (i.e. articles) out there that show how a
CRUD
application would use embedded SQL for all file access? I ask not

because

I
am new to SQL, but because I am not yet convinced of how it's usage is
being
described by some in this thread.

I must say that Alan's comments about lessening the compile burden is
something I hadn't considered to a great extent until I started thinking
about it. Certainly better that wrapping file access with *SRVPGM's

where

the whole record is being passed in/out without applying any sort of
business logic. I think this also comes down to having a good change
management solution that does a lot of the work for you (as it should).
