Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

== Why is this an issue?
|
|
|
|
``++SELECT INTO TABLE++`` is much more efficient than ``++SELECT ... ENDSELECT++``. ``++SELECT INTO TABLE++`` needs more memory to hold the result set, but in normal situations, this is not a concern. When memory is a concern, the result set can be divided into smaller sets.

\[~freddy.mallet] I'm confused by this description. ``++SELECT INTO TABLE++`` is more efficient but it needs more memory...?

Indeed @Ann:
|
|
|
|
* In one case, we we're going to consume less memory but the execution time might be really bigger
|
|
* In the other case, we start by quickly loading all information in memory to then process it
