Using sql subquery in Tableau -


i trying calculate new field in tableau similar sub query in sql. however, numbers not matching when try this. stuck @ point , trying see others have done.

to provide reference, below subquery trying duplicate in tableau.

 select  ((sum(n.non_influenced_sales*n.calls)/sum(n.calls))-(sum(n.average_sales*calls)/sum(calls))))/       (sum(n.non_influenced_sales*n.calls)/sum(n.calls)) impact  (select  count(d.id) calls  ,avg(d.sale) average_sales  ,avg(case when non_influenced=1 d.sale else null end) non_influenced_sales  data d  group skill) n

when try build same calculation in tableau, able same results long comment out group skill. however, when try group skill, attempts match number have not been working.

the closest have come when try fix level of detail expression using include. tableau code:

(include [skill]:([non_influenced_sales]-[average_sales])/[non_influenced_sales]}

however, doing or using fixed has not worked , can't match numbers getting sql.

fyi, impact aggregated measure. built sub-query part in tableau creating separate fields calculation needed. example non influenced sales calculated in tableau:

avg(if [non_influenced]=1 [non_influenced_sales] end)

however, not sure if matters or not.

i have tried creating custom sql. able rolled version using of dates correct. when want down different dates/use other filters, things messy real quick. trying build relationships on date level, hasn't worked either.

is there easier way this?

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
