Very simple BigQuery SQL script won't return "0" for Count rows with no results -

-

i trying make simple sql script work:

select   date(sec_to_timestamp(created_utc)) date_submission,   count(*) num_apples_oranges_submissions   [fh-bigquery:reddit_comments.2008]   (lower(body) contains ('apples')   , lower(body) contains ('oranges')) group   date_submission order   date_submission

the results this:

1   2008-01-07  3     2   2008-01-08  1     3   2008-01-09  2     4   2008-01-10  3     5   2008-01-11  2     6   2008-01-13  2     7   2008-01-15  2     8   2008-01-16  3

as can see, days there no submissions containing both "apples" , "oranges", instead of value of 0 being returned, entire row missing (such on 12th , 14th).

how can fix this? i'm @ wits end. thank you.

try below, return submissions days 

select   date(sec_to_timestamp(created_utc)) date_submission,   sum((lower(body) contains ('apples') , lower(body) contains ('oranges'))) num_apples_oranges_submissions   [fh-bigquery:reddit_comments.2008] group   date_submission order   date_submission

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
