Running Balance in SQL Server 2012 -


i trying running balance using sql server 2012

here got far...

declare @transactions table (     amount decimal (18,2),     transactionid uniqueidentifier,     accountid uniqueidentifier,     transactiondate date )  declare @accountid uniqueidentifier = newid()  insert @transactions (amount, transactionid, accountid, transactiondate) select 3224.99, newid(), @accountid, '2013-06-02'  insert @transactions (amount, transactionid, accountid, transactiondate) select 18.99, newid(), newid(), '2013-06-14'  insert @transactions (amount, transactionid, accountid, transactiondate) select -8.99, newid(), @accountid, '2013-06-14'   insert @transactions (amount, transactionid, accountid, transactiondate) select -6.99, newid(), @accountid, '2013-06-14'  insert @transactions (amount, transactionid, accountid, transactiondate) select -22.14, newid(), @accountid, '2014-11-09'  insert @transactions (amount, transactionid, accountid, transactiondate) select -84.99, newid(), @accountid, '2013-06-09'   select  sum(amount) on (order transactiondate, transactionid) [runningbalance],         amount @transactions  accountid = @accountid order transactiondate desc

results are

runningbalance                          amount --------------------------------------- --------------------------------------- 3101.88                                 -22.14 3133.01                                 -6.99 3124.02                                 -8.99 3140.00                                 -84.99 3224.99                                 3224.99

my goal have runningbalance show each balance, if same day, each row should have own balance

as can see, 2nd row not coming correctly , believe because have 2nd account id conflicting it, assumed statement remove it..

i can remove order by, wanting list newest transaction first, final query have paging, , have tried this.. balance off...

select * ( select  sum(amount) on (partition accountid order transactiondate, transactionid) [runningbalance],         amount, transactiondate @transactions  accountid = @accountid ) results order transactiondate desc     runningbalance                          amount                                  transactiondate --------------------------------------- --------------------------------------- --------------- 3101.88                                 -22.14                                  2014-11-09 3131.01                                 -8.99                                   2013-06-14 3124.02                                 -6.99                                   2013-06-14 3140.00                                 -84.99                                  2013-06-09 3224.99                                 3224.99                                 2013-06-02

i'm not sure problem is...

instead of ordering transactionid (a meaningless guid value has no bearing on when row inserted), need determine proper order in other way. since have createdon column stores date/time row inserted, should add order generate correct sequence.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
