Wait, what? Something doesn't make sense with what you said. You have 30
years of experience writing database programming code AND you are
just now beginning to learn about SQL?
Well, may I suggest you actually COMPREHEND Richter's point when he said
"and only a very small part of people who use Databases use SQL".
I guess you've never heard of NoSQL databases then? As in "No SQL"?
Most of my programming has been done using databases that were what?
maybe five years old before SQL was even thought of! Yes you can use
SQL, but why bother when you have a much more expressive, powerful and
comprehensible language at your finger tips.
Also, it helps a whole lot when writing SQL if you format your statements:
select
c.*,
cc.country_name
from
customers c
join country_codes cc on cc.country_code = c.country_code;
Formatting code really helps legibility, especially when it comes to
SQL. That ought to be one of the first things you learn.
And again you're missing the point. I had two lines, each line with its
own purpose (the first to say what I wanted, the second where to get it
from). Perfectly comprehensible. Your equivalent is just DIFFERENTLY
comprehensible.
But you didn't address my example - let me translate your six lines into
the database access language ENGLISH - it doesn't make sense as more
than a one-liner ...
LIST CUSTOMERS
or if you only want US customers
LIST CUSTOMERS WITH COUNTRY_CODE EQ "USA"
All the crap in your select statement - INCLUDING the join - has been
pushed down into the *table* definition (not the view, the table).
Cheers,

Again, you are someone replying with another confusing response. You say
you have little to no experience with databases, then assert:
"and only a very small part of people who use Databases use SQL"
Assuming people in that sentence, you are referring to people who use
write programs or scripts which make use of databases, if you know very
little about the subject of databases on that subject, how can you
justify this assertion?
Moreover, I am unsure why I might heed your advice with regard to
effective writing. Looking back at the messages, your grammar,
formatting, and sentence structure belie someone with little formal
education on the subject.

"Then maybe a simple form. but threads and sockets... ok.. well I know
what threads and sockets are because I happened to use them... but to a
newbie... YIKES what are those?? and SQL??? What the heck is that anyway?
I'm not talking about a newbie.. I mean.. myself... with over 40 years of
programming experience, mostly with Pascal, What the heck is it and why
would I need to monitor it?"
Your first sentence has no verb. Your profuse usage of strings of
punctuation is both non-standard and inconsistent. It's difficult to
tell whether you meant to have a pause, where a comma would be
appropriate, or whether an idea has ended and a single period should be
used.
Grammar is important to writing effectively for a number of reasons.
First and foremost, grammar is the set of rules that govern the way
words are used in a language. It helps to ensure that people can
communicate effectively and understand each other. Without a common set
of grammatical rules, it would be much harder for people to convey their
thoughts and ideas clearly and for others to understand them. I would
hope a programmer with 40 years of experience would recognize this. Good
grammar is essential for written communication, whether it's a business
letter, a school essay, or an email to a friend. Poor grammar can make
writing difficult to understand and can convey a lack of attention to
detail or professionalism.
Finally, grammar is important for language learning. Learning grammar
helps language learners understand how the language works and how to use
it correctly. It can also help them understand the structure of
sentences and how to build them, which is important for speaking and
writing in the language.
I suggest you either brush up on these subjects or refrain from scolding
people on subjects with which you have no practical experience.
