tsql - Get max value within an inline view having a TOP clause -


i trying max value within inline view , returning me maximum value within inline view if inline view had no top clause.

the table dbo.details in query below contains 650 records. need max value top 200 records, query below gets me max value on records in details table batchnumber = 341.

is there subtle point missing? goal max value within top(200) records. using sql server 2008 r2.

select   max(a.detailsrecordid)  (select top(200) npd.detailsrecordid,         npd.batchnumber  dbo.details npd npd.batchnumber = 341)

top 200 based on nothing. there no order by.

even table clustered pk there no guaranteed order without order by.

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!
