Storing and Accessing a Range of Numbers / Dates in MySQL -


i need store range of numeric or datetime values in mysql, preferably in single column. unfortunately, there no real array or set data-types in mysql, likewise seems there no range data-type, i'm bit @ impasse here, hoping come smart.

common use cases range e.g. storing start , end times of event, or minimum , maximum prices of given product.

in case, need store year(s) book written. in cases, there ambiguity , year have on record may e.g. 810-820. of course 1 way go have separate year_min , year_max columns, , have identical data stored in both columns in case there no variance.

yet fraction of entries have need have such range stored, , i'd love query simple between 750 , 850 example -- , avoid both having where hit on 2 columns, redundant duplication of data in 98% of cases.

what's recommended approach? best practice tips? know how tune decent two-column queries. i'm hoping there's way go this... (and no, i'm not switch postgresql just have benefit of range types.)

i recommend going 2 column solution, despite not sexy or clever. suppose implement 1 column. database becomes non relational, because given record , column points multiple values (year_min , year_max). though schema might appear tidy, might lose benefit in form of more difficult queries.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
