i trying open angular accordian in header.html clicking button in body.html . triggering event in 1 view different view. have idea how in angular? what can using events let accordion directive know happend or use shared service. considering performance, not make huge difference, if use $emit instead of $broadcast since event fired via $emit bubbles scope hierarchy , $broadcast sends event down. make sure fire event on $rootscope , won't event bubble anymore. so in case want use events have method on component fires event via $emit on $rootscope follows: function openaccordion() { $rootscope.$emit('on-accordion-open', null); } you use in view, e.g. in body.html . remember function above part of directive / component or controller. <button ng-click="vm.openaccordion()">open accordion</button> also note assume using controlleras syntax (set vm ). in accordion directive can hook listeners several events example on-accor

this exercise wikibooks, #6 the table schema the question is: for each piece, find expensive offering of piece , include piece name, provider name, , price (note there 2 providers supply same piece @ expensive price). the solution: select pieces.name, providers.name, price pieces inner join provides on pieces.code = piece inner join providers on providers.code = provider price = ( select max(price) provides piece = pieces.code ); i don't understand subquery part. think typical way find max price select max(price) provides group piece; in way, can not use price = subquery or price in subquery, , sub query in solutions, looks like select max(price) provides, pieces provides.piece=pieces.code; it return biggest number, can not figure out why can 'group' , return right rows. although thomas provide simpler solution, lets original question, why work. select pieces.name, providers.name, price pieces
