sql - Where clause affecting two different select statements -

-

i need count payers , mortals separately have zip code of 44444. zip codes stored in same tables ids on 2 separate tables in many-to-many relationships. have written this:

select count(mortal_zip) "mortals in 44444"       ,count(payer_zip) "payers in 44444"         (select am.zip_code mortal_zip          address          join mortal_address            on mortal_address.address_id = am.address_id          join mortal            on mortal.mortal_id = mortal_address.mortal_id         trim(am.zip_code) = '44444'        ) m,       (select ap.zip_code payer_zip          address ap          join payer_address            on payer_address.address_id = ap.address_id          join payer            on payer.payer_id = payer_address.payer_id         trim(ap.zip_code) = '44444'        ) p;

i know this: there no payers zip code of 44444 there 3 mortals zip code of 44444. reason getting there 0 mortals zip code of 44444. if ask mortals in 44444, needed. if ask count of mortals , count of payers 444444 0 on both sides.

additionally, have tried re writing whole thing sub selects. 

select count(m.mortal_zip) "mortals in 44444"       ,count(p.payer_zip) "payers in 44444"         (select am.zip_code mortal_zip          address         trim(am.zip_code) = '44444'           , am.address_id in              (select mortal_address.address_id                 mortal_address                mortal_address.mortal_id in                   (select mortal.mortal_id                      mortal                    )               )        ) m,       (select ap.zip_code payer_zip          address ap         trim(ap.zip_code) = '44444'           , ap.address_id in              (select payer_address.address_id                 payer_address                payer_address.payer_id in                     (select payer.payer_id                        payer                     )               )         ) p;

i same result.

why function in different select statement affecting other select statement?

update

i've re written query these 2 queries returning different values.

this:

select m.mortal_zip "mortals in 44444"       ,p.payer_zip "payers in 44444"         (select count(am.zip_code) mortal_zip          address         trim(am.zip_code) = '44444'           , am.address_id in              (select mortal_address.address_id                 mortal_address                mortal_address.mortal_id in                   (select mortal.mortal_id                      mortal                    )               )        ) m,       (select count(ap.zip_code) payer_zip          address ap         trim(ap.zip_code) = '44444'           , ap.address_id in              (select payer_address.address_id                 payer_address                payer_address.payer_id in                     (select payer.payer_id                        payer                     )               )         ) p;

returns:

mortals in 44444 payers in 44444 ---------------- ---------------                3               0

this:

select mortal_zip "mortals in 44444"       ,payer_zip "payers in 44444"         (select count(am.zip_code) mortal_zip          address          join mortal_address            on mortal_address.address_id = am.address_id          join mortal            on mortal.mortal_id = mortal_address.mortal_id         trim(am.zip_code) = '44444'        ) m,       (select count(ap.zip_code) payer_zip          address ap          join payer_address            on payer_address.address_id = ap.address_id          join payer            on payer.payer_id = payer_address.payer_id         trim(ap.zip_code) = '44444'        ) p;

returns:

mortals in 44444 payers in 44444 ---------------- ---------------                5               0

your query trying join empty result set result set has 3 rows. of course, returns empty result set. instead, run subselects counts themselves, or alternatively:

select     count(ma.address_id) "mortals in 44444",     count(pa.address_id) "payers in 44444"     address left outer join mortal_address ma on ma.address_id = a.address_id left outer join payer_address pa on pa.address_id = a.address_id     a.zip_code = '44444'

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...
