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?
|
|
|
|
Having all branches in a ``++CASE++``, ``++IF++`` or ``++IIF++`` chain with the same implementation is an error. Either a copy-paste error was made and something different should be executed, or there shouldn't be a ``++CASE++``/``++IF++``/``++IIF++`` chain at all.

=== Noncompliant code example
|
|
|
|
[source,sql]
|
|
----
|
|
IF @x < 25 -- Noncompliant
|
|
PRINT 'A'
|
|
ELSE IF @x < 10
|
|
PRINT 'A'
|
|
ELSE
|
|
PRINT 'A'
|
|
|
|
SELECT
|
|
CASE col1 -- Noncompliant
|
|
WHEN 1 THEN 'A'
|
|
WHEN 2 THEN 'A'
|
|
ELSE 'A'
|
|
END,
|
|
IIF(col1 < 25, 'A', 'A') -- Noncompliant
|
|
FROM table1

|
|
|
|
=== Exceptions
|
|
|
|
This rule does not apply to ``++IF++``/``++CASE++`` chains without ``++ELSE++`` clauses.

IF @x < 25 -- no issue, this could have been done on purpose to make the code more readable
|
|
PRINT 'A'
|
|
ELSE IF @x > 10
|
|
PRINT 'A'
