/**
* PmWiki module to run a MySQL SELECT query based on info provided as parameters
* in the (:selectquery:) tag or via a form.
* Versions prior to 1.3 Written for Permaculture Collaborative,
* Copyleft June 2006, 23 February 2007 by Ben Stallings <ben@interdependentweb.com>
* Version 1.4 : AS clause in linked colums codded by Guy Moreau <gmyx@gpws.ca>
* Version 2.0 Beta 1, March 29th 2007, by Guy Moreau <gmyx@gpws.ca>.
* * Added display options:
* * norowcount: do not display the number of selected rows
* * noheaders: do not display the header row
* * div: display using divs instead of tables (example of use is with single column data)
* * debug: allows to output the select string for debug purposes
* * Converted to database standard
* * Fixed a bug with fields that were both in the columns list and linked fields not showing
* Current TODO:
* * currently cannot handle some fully qualified and some not fully qualified when dealing with links
* Version 2.0 Beta 2, April 9th, 2007, by Guy Moreau <gmyx@gpws.ca>
* * Attemp at backwards compatibility: uses the 1.x constants and maps them to a DB standard offering
* * Added RecipeInfo
* * Added pagination variables and markup - as request by GhostRider.
* Version 2.0 Beta 3, April 3rd, 2007, by Guy Moreau <gmyx@gpws.ca>
* * Major rewrite of code to fix fully qualified names
* * Bug fix: SelectQuery will not display columns that are fully qualified
* * Multiple parameters can be added to the link array
* * Made $SQofflimits a SDVA array so that it can be configured in config.php as per Ben's request
* * Output is in strait HTML - faster processing!
* Version 2.0 Beta 4, July 06, 2007 by Guy Moreau <gmyx@gpws.ca>
* * Bug fix: An mysql statement was left in the error code. Converted to adodb.
* * Bug fix: A string literal in the link statement would cause recipy to fail
* Version 2.0 Beta 5, January 27th, 2008 by Guy Moerau <gmyx@gpws.ca>
* * Bug Fix: 'as' statement was not being honered in column headers
* * Clean up some code in the query row section - redundent access to field data
* * Bug Fix: On some installs, results were always blank.
* Version 2.0 build 6, March 18th, 2008 by Guy Moreau <gmyx@gpws.ca>
* * No more beta, just builds.
* * Added 'type' parameter to match/against pair to use like instead of full text search
* Version 2.0 build 7, December 21, 2008 by Guy Moreau <gmyx@gpws.ca>
* * New variables:
* * * $SQDelim incase the period is something else
* * * $SQFieldId incase the DB uses something else than '`'
* * Bug Fix: backtics causes the parser to ignore fields names
* Version 2.0 Build 8, June 20, 2009 by Guy moreau <gmyx@gpws.ca>
* * Changed Variables intoduced in b7 into the $SelectQuerySettings[] array since it didn't work
* * * $SQDelim becomes 'Seperator', defaults to '.'
* * * $SQFieldID becomes 'FieldId', defaults to '`'
* * Added Varibalbe 'TableId' to $SelectQuerySettings[], default none
* * By Request: New paramerter to select run-time the connection for multiple connections
* * * connection = "" selects the array with the same name in config.php to use
* * Bug Fix: Empty FieldID causes warnings has been fixed.
* future TODO:
* * examine possible table enhancements
* * examine possible page id overloads
* * format pagination section
* * Get rid of the custom markup for {`variables`} and (conditionals), using $FmtPV and $Conditionals instead.
* * one mysql statement remains, but in an obsure section of the code. Need to find a suitable replacement
* * after 2.0 release, add id to create more accessible tables
* * add a config variable to define wildcard value
*
* * Database constants (DB_*) must be defined in config.php or here. (applies to version 1.4 and earlier only or version 2.0 beta 2 and later)
* OR the Database standard must be installed and configured for version 2.0 beta 1 or later.
