database - Azure Table Storage query for records based on property that may not exist for all records -

-

i using azure table storage service , trying introduce soft delete feature it. adding property ismarkedfordeletion entries marked deletion. when query, need entries not marked deletion. in fields not deleted, ismarkedfordeletion not exist.

i have tried following:

<...query...> , (ismarkedfordeletion ne true) <...query...> , (ismarkedfordeletion eq false) <...query...> , (not (ismarkedfordeletion ne false)) <...query...> , (not (ismarkedfordeletion eq true))  <...query...> , (not (ismarkedfordeletion eq null)) => returns 501 not implemented

none of them showed entries did not have ismarkedfordeletion property in them.

what do records not have ismarkedfordeletion records ismarkedfordeletion property exists, false?

i have thought scrubbing database , adding ismarkedfordeletion records, or filtering results myself after query executed, in query easy me while creating segmented requests , paging results.

i not think possible, try check if field equal null, don't know if solve issue. table storage has no schema, , not intended used querying fields other partition key , row key. think result faster getting result given pk+rk , filtering them out later out, leaving table storage filter on field not in pk+rk pair.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana
