Make the GROUP_CONCAT aggregate function not repeat values (closes #3223975)
Work on sets instead of arrays, so if the same value appears twice it's
not repeated in the concatenated output.
This patch handles the postgresql and sqlite backends, mysql is left
alone at this point (seems doable, but I don't have time or motivation
to fix and test it).
Javascript Coding Standards
---------------------------
(Draft, to be continued)
:Naming: camelCase, except for CONSTANTS
Indentation rules
~~~~~~~~~~~~~~~~~
- espace avant accolade ouvrante
- retour à la ligne après accolade ouvrante (éventuellement pas
de retour à la ligne s'il y a tout sur la même ligne, mais ce n'est
pas le cas ici.
- no tabs
Documentation
~~~~~~~~~~~~~
XXX explain comment format for documentation generation
Coding
~~~~~~
- Don't forget 'var' before variable definition, and semi-colon (';') after **each** statement.
- Check the firebug console for deprecation warnings
API usage
~~~~~~~~~
- unless intended, use jQuery('container') rather than jqNode('container')
