APEXPosed 2012

If you missed out on this year's KScope conference, you missed out on a tremendous amount of APEX content.  You missed the APEX 4.2 preview and discussions from Oracle.  You missed great sessions on the APEX Listener, jQuery, Dynamic Actions, etc.  You missed the opportunity to actually meet some of the best APEX experts on the planet.Fear not! APEXposed has you covered!APEXposed is a 2-day conference focused exclusively on APEX technical sessions.  A subset of the presenters from KScope will be presenting their sessions again in Montreal, Quebec this September 11th & 12th at the Centre Mont Royal.  And the best part?  You can attend this 2-day conference for as little as $350!  That's less than $30 per session!If you register by August 15th and use the discount code ENKITEC, you'll get the $350 price.  If you wait too long, the standard conference rate of $450 will apply, but the discount code will still be good.Hope to see you in Montreal!

Consider this example: you have 10 different widget types, and 10 of each type for a total of 100 units. Here's some SQL to quickly create this scenario, if you want to follow along: CREATE TABLE widgets (widget_type VARCHAR2(10)) / DECLARE z NUMBER := 1; BEGIN FOR y IN 1..10 LOOP FOR x IN 1..10 LOOP INSERT INTO widgets VALUES ('Type ' || z); z := z + 1; END LOOP; z := 1; END LOOP; END; / If you wanted to sum them based on type and just see the first five types, you can use a simple SQL statement like this: SELECT NULL link, widget_type label, COUNT(*) value FROM widgets GROUP BY widget_type ORDER BY 2 Which will in turn, p…
