sql server - how can i group them in two different groups use only single column -


how can group them in 2 different groups use single column

sample data:

 date_entry  time_start  time_finished idle_code    qty_good 8/8/2013    13:00       13:30            6            10      8/8/2013    13:30       15:20            0            20 8/8/2013    15:20       15:30            6            5  8/8/2013    15:30       16:25            0            10 8/8/2013    16:25       16:40            7            0 8/8/2013    16:40       17:25            0            40 8/8/2013    17:25       17:40            3            10 8/8/2013    17:40       24:00            1 8/8/2013    24:00       00:00            1 8/8/2013    00:00       00:30            1

result

                              idle_code   total mins.         idle time   #1  410:00  mins         idle time   #2  0:00    mins         idle time   #3  15:00   mins         idle time   #4  0:00    mins         idle time   #5  0:00    mins         idle time   #7  15:00   mins         idle time      #0,6     250:00  mins  (a) total idle time         440:00mins(idle time #0,6 not include) (b) total operation time        250:00mins(idle time #0,6 only)

how can total sum of idle_code 1 or how can group them sum??

sample sql

select       dbo.t_monitoring_pi_oper_entry.wo_number,         dbo.t_monitoring_pi_oper_entry.qty_rejected,         dbo.t_monitoring_pi_oper_entry.operator,         dbo.t_monitoring_pi_oper_entry.reject_code,         dbo.t_monitoring_pi_oper_entry.qty_good,         dbo.t_monitoring_pi_oper_entry.idle_code,         dbo.t_monitoring_pi_oper_entry.time_finished,         dbo.t_monitoring_pi_oper_entry.time_start,         dbo.t_monitoring_pi_oper_entry.date_entry    dbo.t_monitoring_pi_oper_entry    

     select sum(dbo.t_monitoring_pi_oper_entry.time_finished,1,0)        dbo.t_monitoring_pi_oper_entry       group idle_code

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!
