Some of us while writing an SQL select statement with a join between two tables or more
may get confused with whether to add a certain condition to the "ON" clause of the join or
just add it to the "WHERE" clause as if it is just a filtering condition. Some people may think
that both approaches will return the same results every time. This is not completely true.
Yes in some cases both approaches will return the same results but in other cases they
won't. If you want to know more, you can read this article.
[Development Simply Put] The Difference
Between SQL Join Conditions Into "ON" And
"WHERE" Clauses
"If you can't explain it simply, you don't understand it well
enough" -Albert Einstein
I am "Ahmed Tarek" the owner and author of the "Development Simply Put" blog. During my career
days and day after day I got more confident that it's all about sharing not the title you have. I believe
that everyone has something to share whatever small he thinks of it. Sometimes a great idea comes
out of just a tiny idea and the same for knowledge. I always try to gain knowledge and learn new skills
and I found that the best way to learn is to try to teach what you already know. This makes you think
of the best simplest way to explain complex logic which makes you spot some points may be even
yourself didn't recognize in the first time.
The greatest thing in the human mind is that it carries out too complicated operations and finally
presents it into a simple form, so why do we always try to re-complicate things? This is what
encouraged me to start my blog -Development Simply Put
(http://developmentsimplyput.blogspot.com)- trying to do my best to simplify main concepts in IT
development and share my humble knowledge in this field.
