sql server - SQL view with dynamic count of columns -

-

i know impossible directly, maybe of sql functions possible create view dynamic column count? want - create view which's columns username (first table's values), date (second table's values), , multiple columns properties (each third table's row column).user table structure - id , username, date table structure - id , datetime, property table structure - id, property name, property value, fk user id (plus 1 table relate tables). result should (columns):

|username| date | property 1|....|property n|

can show simple sample ?

this not possible in standard sql, nor in version of sql familiar (sql server, oracle, mysql, access sql). tables, expressions , views in sql have fixed column-set, design. i.e., it's intentionally restricted way. afaik, in versions of sql, stored procedures objects can return variable column-set.

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...
