rspec/rules/S126/plsql/rule.adoc

This rule applies whenever an ``++IF++`` statement is followed by one or 

more ``++ELSEIF++`` statements; the final ``++ELSEIF++`` should be followed by an ``++ELSE++`` statement.


The requirement for a final ``++ELSE++`` statement is defensive programming. 

The ``++ELSE++`` statement should either take appropriate action or contain 

a suitable comment as to why no action is taken. This is consistent with the 

requirement to have a final ``++ELSE++`` clause in a ``++CASE++``

statement. 

== Noncompliant Code Example

----
IF my_variable = 0 THEN
  do_something;
ELSIF my_variable = 1 THEN
  do_something_else;
END IF;
----

== Compliant Solution

----
IF my_variable = 0 THEN
  do_something;
ELSIF my_variable = 1 THEN
  do_something_else;
ELSE
  -- Nothing has to be done.
  NULL;
END IF;
