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?
|
|
|
|
For better readability, column aliases should be used with the ``++AS++`` keyword. If it is missing, it could be misread as another column being selected.

DECLARE
|
|
result DUAL.dummy%TYPE;
|
|
BEGIN
|
|
SELECT
|
|
dummy d -- Non-Compliant - could be misread as selecting both "dummy" and a column "d"

result

FROM

DUAL;
