Subject: SQL Question - Select * versus selecting all fields individually
Hi Everyone,
Someone here with lots of SQL experience but none with System i says:
"My 2 cents on your code is not to use Select *. Always list the columns
solely for performance reasons."
My thinking is to select all columns into an externally described DS based
on the table so I have everything I might need.
I could:
(a) keep my code as is, using select *, or
(b) select every field individually
(c) only select the fields I need, or
What is everyone doing when using embedded SQL?
Tks,
Glenn Gundermann
