Stan Bradbury commented on DERBY-384:
-------------------------------------

Stan's Review of: %%% Tuning Guide:  Internal language transformations


  >> ON PAGE: 
http://incubator.apache.org/derby/docs/tuning/ctuntransform35783.html
		Predicate transformations
  ** the link list at the bottom appears TWICE.  Remove duplicate list.

  >> ON PAGE: http://incubator.apache.org/derby/docs/tuning/rtuntransform208.html	
	  **   Remove duplicate link list.

   >> ON PAGE: http://incubator.apache.org/derby/docs/tuning/ctuntransform11313.html
		View transformations
  ** 	a) remove the link:  ' Materialization ' - it is not related
  ** 	b) Remove duplicate links list (should have two links).

  >> ON PAGE
http://incubator.apache.org/derby/docs/tuning/ctuntransform13699.html
	Subquery processing and transformations
 **  Remove duplicate (the SHORTER) link list.  5 item list is correct.

  >>ON PAGE:
http://incubator.apache.org/derby/docs/tuning/ctuntransform16033.html
	Sort avoidance
	  **   Remove duplicate link list.

  >> ON PAGE:
http://incubator.apache.org/derby/docs/tuning/ctuntransform16279.html
	DISTINCT elimination based on a uniqueness condition
  ** 	CHANGE BULLET POINT:  Secondary table 
  ** 	NEW TEXT: Secondary table(s)

  >> AND  **  clarify these TWO comments by using this text (I added the terms in 
	parenthesis - after the words 'only table' and 'Primary table'):

-- all the columns in the index on the only table (tab1) appear
-- in the way required for the Primary table (simple column references)
SELECT DISTINCT c1, c2, c3, c4

-- all the columns in the index on the only table (tab1) appear
-- in the way required for the Primary table (equality predicates)
SELECT DISTINCT c3, c4

> This issue tracks comments for the manual known as Tuning Derby. The deadline for posting
comments is Tuesday, June 28, noon Pacific time.
> Some guidelines to follow when posting comments to this issue are:
> - Try to make clear and concise comments about what you want changed whenever possible.
 Provide concrete comments that say "Please change <original> to <modified>" instead
of generic comments like "This section needs to be rewritten."
> - If you're reviewing the HTML Files copy, include the URL for the page in the review
comment. Obtain the URL like this:
>     * highlight the topic in the left frame
>     * right click
>     * choose "Properties"
>     * copy and paste the address in the pop up box.
> - If you're reviewing the PDF copy, in the review comment:
>     * Include the page number for the PDF, and indicate whether the number is the PDF
sheet number or the printed page number.
>     * Include the title of the section that the problem occurs in. If it's in a subsection,
try to include the hierarchy of titles.
> - Please don't review the HTML Book copy -- it'll be time consuming to match up that
copy with the underlying DITA source.
