datetime - SQL Server 2012 Time Range Check? -


what smart way determine if current time between 59th minute of hour , first minute of next hour, using pure tsql on mssql 2012?

i not want cut off time "now", want cut off date , time calculation.

this gets me kind of close : datepart time between (instead of convert date) not since need calculate based on current time , not table values.

the following might illustrate if server in "the bad time" , should return value of '1'

14:58:59 ,  should not considered in "bad time" 14:59:00 ,  should considered in "bad time" 14:59:04 ,  should considered in "bad time" 14:59:57 ,  should considered in "bad time" 15:00:02 ,  should considered in "bad time" 15:01:26 ,  should not considered in "bad time" 15:02:00 ,  should not considered in "bad time" 15:02:01 ,  should not considered in "bad time"

thanks.

edit:

this code works, sure can done more efficiently. recommendations welcomed. again.

declare @now time = ( select cast( sysutcdatetime() time  )) declare @floor time = ( select dateadd( minute , 59 , ( dateadd(hour,datediff(hour,0,@now),0) ) ) ) declare @ceiling time =(  select dateadd( minute , 2 , @floor ) ) if ( @now > @floor , @now < @ceiling ) begin     select 1 bit end select @now , @floor , @ceiling

please replace @dt required:

declare @dt datetime = '20130419 21:59:01'  select case when datepart(minute, @dt) in (59,0)             'minute between 59 , 1'             else 'minute not between 59 , 1'        end myminute

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!
