i have trouble using geography calculate distance in miles using format of table. latitude , longitude of both locations side side: id | a_latitude | a_longitude | b_latitude | b_longitude i'm trying point of a , along point of b , , return distance between a , b in miles. i've tried few things, including similar to: declare @orig geography declare @end geography select @orig = geography::point(a_latitude, a_longitude, 4326) ,@end = geography::point(b_latitude, b_longitude, 4326) table1 select round(@end.stdistance(@orig)/1609.344,2) miles ,@end.stdistance(@orig) meters ,table1.* table1; where i'm getting repeating value miles , meters across rows. please suggest how should structuring query i'm looking for? edit: sql surfer! with x (select geography::point(a_latitude, a_longitude, 4326) ,geography::point(b_latitude, b_longitude, 4326) b ,id table1) select round(x.b.stdistance(x.a)/1609.344,2) miles ,x.b.stdistance(x.a) mete

in spacebars template, have javascript array x , index i , eg. template.test.helpers({ 'foo': function() { return { x: ['aa','bb','cc'], i: 1 } } }); i can access fixed elements of x in template {{ x.[1] }} : {{template name="test"}} {{#with foo}} {{x.[1]}} {{/with}} {{/template}} but {{ x.[i] }} doesn't work. how can access x[i] ? thanks! one solution define custom helper: template.test.helpers({ 'getelement': function(a, i) { return a[i]; } }); and in template, use: {{ getelement x }}
