New Oracle Q&A site

I saw many posts about new Eddie Awad’s site Oracle Questions and Answers. Some of them criticize it some of them recognized it as a new Oracle Q&A site.
It was interesting to read what Tom Kyte and Howard Rogers wrote about it. One simple solution presented on Oracle Q&A produced big and strong discussion about possibility of one table to be read-only.
Howard Rogers did research about this possibility and as a result he got that one Oracle table could not be read-only in real meaning of the phrase “read-only”. So, his standing point was that this site does not provide real and true information.

From my perspective, this is good and useful site. You can find very useful information there. I agree that some of the answers are short, but sometimes it is better to get the idea, so you can extend it and adapt it to your needs.

Recently, I found very good solution how to generate sequence numbers between two numbers. For this purpose I was always using one table filled with sequential numbers from x to y. I was creating new rows whenever I needed it. But, the solution presented at Oracle Q & A, is so simple and practical.

select (lvl + &v_from - 1) myseq
from (
select *
from (
select level lvl
from dual
connect by level <= (&v_to - &v_from) + 1
)
)
order by myseq

This is very good place where you can find useful tips.

Sincerely,
Mihajlo Tekic
