sql server - How to create a multiple variable in SQL? -

-

i trying calculate a, sort of, moving average data in sql server 2008, way have found using @variable. example have set of data:

studydate  cpty value ---------- ---- ---------------------- 2015-11-24 1    3009 2015-11-24 2    2114 2015-11-24 3    558 2015-11-24 4    121 2015-11-24 5    2515 2015-11-24 6    81 2015-11-24 7    80 2015-11-24 8    1534 2015-11-24 9    136 2015-11-24 10   5674 2015-11-25 1    2731 2015-11-25 2    2197 2015-11-25 3    550 2015-11-25 4    124 2015-11-25 5    2532 2015-11-25 6    81 2015-11-25 7    80 2015-11-25 8    1700 2015-11-25 9    122 2015-11-25 10   5788 2015-11-26 1    2666 2015-11-26 2    2175 2015-11-26 3    408 2015-11-26 4    124 2015-11-26 5    2545 2015-11-26 6    81 2015-11-26 7    81 2015-11-26 8    1712 2015-11-26 9    122 2015-11-26 10   5967

and want find moving average every day. if run query:

declare @studydate date = '2015-11-26' select  @studydate,         cpty,         avg(value) #movavg studydate > dateadd(m,-1,@studydate) , studydate <= @studydate group cpty order cpty

then average 1 day '2015-11-26', can average every day every cpty?

thank in advance!

in sql server 2008, using outer apply. i'm not sure mean "moving average", appears average previous month.

so:

select t.*, tavg.value t outer apply      (select avg(t2.value) value       t t2       t2.cpty = t.cpty ,             t2.studydate > dateadd(month, -1, t.studydate) ,             t2.studydate <= t.studydate      ) tavg;
