Lesson 3.
Lesson learned
Write in easy to edit way. Especially useful to select fields in SQL , parts of concated messages.

Why
Someone is known to write with pencil with eraser on it. We have commenting / Erace options when we write code but the ease of use can differ...

How to
For sql select fields, write each one from new line and place "," before:

select
field1
,field2
,field3

so you can "comment" it at one commenting.

or concating using VBA

concated_string= _
"concated" _
& "string" _
& "smth" _
& "else"

How I learned
I think all my learning were about emotions, but here it were my ones toward code I first saw in my organization.
"," prior the item of the list looked weird.
But it's super useful and I happy I learned it :)
