Inline adoc when include has no additional value (#1940)
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?
``++@@IDENTITY++`` returns the last identity column value created on a connection, regardless of the scope. That means it could return the last identity value you produced, or it could return a value generated by a user defined function or trigger, possibly one fired because of your insert. In order to access the last identity value created in your scope, use ``++SCOPE_IDENTITY()++`` instead.
=== Noncompliant code example
[source,sql]
----
INSERT ...
SET @id = @@IDENTITY -- Noncompliant
----
=== Compliant solution
[source,sql]
----
INSERT ...
SET @id = SCOPE_IDENTITY()
