      Description

      This rule applies whenever an IF statement is followed by one or more ELSE IF statements; the final ELSE IF 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 @x = 1
        PRINT 'A'
      ELSE IF @x = 2
        PRINT 'B'
      ELSE IF @x = 3
        PRINT 'C'
      -- Noncompliant; final ELSE is missing
      

      Compliant Solution

      IF @x = 1
        PRINT 'A'
      ELSE IF @x = 2
        PRINT 'B'
      ELSE IF @x = 3
        PRINT 'C'
      ELSE
        PRINT 'Z'
