Don’t use global variables–ever.

From what I’ve seen, whenever someone uses a global variable, it’s
because the person washaving difficulty figuring out how to get data
from
one scope into another (and sometimes back again). It’s true that using
global variables is pretty much never the right answer, if for no other
reason than the fact it can cause issues if there are two globals with
the same name.

So, yeah, yours is decent advice. There’s just one problem: when people
say “don’t use globals” and leave it at that, they give the people who
used globals no ideas what other recourse they have available to them.
Don’t just say “don’t use global variables”. Try saying “You could do
this other thing instead, to get what you need without using a global
variable.”

make sure your definition of List includes a parameter for the dbh
handle:

def List(dbh, other, parameters)
# stuff
end

Now use something like this:

DB_parc.session { |dbh|
schema=“sparc”
List(dbh, schema, other, stuff)
}

You posted no code in your first post, nor did you post a question.

In your second post, you posted no code and then you asked a question
about your invisible code.

Do you really expect any relevant help?

Problem with your provider / News reader / or something else … I

You posted no code in your first post, and you posted no code in your
next post. So no one has any idea what your questions is or what you are
talking about.

Is there something wrong with your mail user agent? I saw code. This
is
an excerpt from the original message:

I’m not sure why he has blockquote characters at the beginnings of all
those lines of code, but that’s definitely code – and it’s not all the
code that was in that message, either.
