sql - returning id in order from query -

-

say have following query 

select *  foo  p_key in (5,7,2,6);

when enter query, p_key values return rows in order of 2,5,6,7. how can make returns rows in order entered in in clause

this

p_key 5 7 2 6

not this

p_key 2 5 6 7

you can't directly order order of items in in clause. you'll have create temporary table or in-line sub-query add order values:

select foo.* foo inner  join (    select 5 [key], 1 [order]    union    select 7 [key], 2 [order]    union    select 2 [key], 3 [order]    union    select 6 [key], 4 [order] ) j on p_key = j.key order j.[order]

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...
