sql server - Pivot query error when added to a stored procedure, but runs OK in query builder window -

-

when run query in regular sql runs fine , correct results. now, want make query dynamic having user add dates such @dtfrom , @dtto date. these user supply dates application. now, i'm trying create stored procedure in sql server run this, these error ")" mis-placed. have looked @ , test portion of query without success.

create procedure dbo.[usp_cleaner_kg_per_date] @dtfrom datetime, @dtto datetime  begin set nocount on; declare @query varchar(4000) declare @packdate varchar(2000)  select  @packdate = stuff(( select distinct                         '],[' + ((left(convert(varchar, packdate, 120), 10)))                            vw_cleanersummary2015 (packdate >= @dtfrom) , (packdate <= @dtto)                         order '],[' + ((left(convert(varchar, packdate, 120), 10)))                         xml path('')                         ), 1, 2, '') + ']'  set @query = 'select * ( select     id,kg,packdate         vw_cleanersummary2015 group packdate,id,[kg/hr] )t pivot (sum(kg) packdate in ('+@packdate+')) pvt'  execute (@query)

if of procedure code issue missing closing end after execute match opening begin.

c++ - Delete matches in OpenCV (Keypoints and descriptors) -

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor...

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a...
