• Check if row exists, if not add it [MySQL]

  - by Steven

  I need to add a row to a MySQL database table but only if the row doesn't already exist. My database server just went down so I can't test this, but will this work as expected? INSERT INTO `blocks` (`block_file`,`settings_group`) VALUES ('announcements','announcement_settings') WHERE NOT EXISTS (SELECT `block_file`,`settings_group` FROM `blocks` WHERE `block_file`='announcements' AND `settings_group`='announcement_settings') It seems like sound logic. Is this a valid query or is there a better way of doing this?

• Add rel="xx" to jQuery a.link elements

  - by Xavier

  I use a little jQuery script to run a simple music player, but I'd like to add a rel="player" to the links in this jQuery script (the play/stop button for instance). This way I can exclude these rel="player" links from another jQuery script I use, because I don't want it to take the rel="player" elements into account. I reckon this is fair simple but i don't really know how to to it. Here is the jQuery script of the player, if it's ever necessary: http://hyker.be/cv/js/jquery.simpleplayer.min.js

I have written a Visual Studio extension that has an IOperationContractGenerationExtension implementation, but this interface only seems to expose the ability to modify the service interface, not the ClientBase-derived class. Is there any way to generate new methods in the proxy client class?
