object - Case Else Statement from different tables -


i trying retrieve name based on type of claim. seem easy enough, it's not working me. working 2 main tables, claim , exposure, , contactname table. each claim can have multiple exposures, each exposure can have 1 claim. both tables contain nameid field - claim.nameid , exposure.nameid. nameid correlates contactname table.

contact name

id name
111 jim
222 bob
333 john
444 sam
555 walt

normally, each claim can have multiple exposures , exposures on claim can have same name or different names. name ids found on exposure.

the exposure.nameid joins contactname.id

claim claim.nameid exposureno exposure.nameid name
a null 1 111 jim
a null 2 222 bob
a null 3 333 john
b null 1 444 sam
b null 2 444 sam

workers comp claims different. each workers comp claim can have multiple exposures, exposures have same name. since exposures on claim have same name, name ids found, not on exposure table, claim table. go figure… claim.nameid joins contactname.id claimcontactname.

claim claim.nameid exposureno exposure.nameid name
c 111 1 null jim
c 111 2 null jim
c 111 3 null jim
d 555 1 null walt
d 555 2 null walt

i can names non workers comp claims , can names workers comp claims. however, when put 2 queries together, don’t results. 

select case when @select(claim\policy type) = 'workers'' compensation' case when claimcontact.name null , claimcontact.name.firstname null claimcontact.lastname when claimcontact.name not null claimcontact.name else claimcontact.firstname + space(1) + claimcontact.lastname end else case when contact.name null , contact.firstname null contact.lastname  when contact.name not null contact.name else contact.firstname + space(1) + contact.lastname end end

haven’t done of this, use figure out. thank in advance.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom...
