Execute a sql string in sql server -

-

my code below, somehow there error near @name

declare @name nvarchar(max)  =  '(mm.dll, ben , jerry.exe)' declare @sql nvarchar(max)= 'select ordername,    customer.version,    count(distinct company.cid) counts [companydata] company   inner join [vendor] mav on company.cid = mav.cid   left outer join [customer] customer on company.vendorid = customer.vendorid , company.did = customer.did ordername in' + @name+ '   group            customer.version, ordername'  exec sp_executesql @sql

put single quote in declaration of @name , remove hashes(#) in it:

declare @name nvarchar(max)='(''mm.dll'', ''ben , jerry.exe'')' declare @sql nvarchar(max)=         'select                ordername,               customer.version,               count(distinct company.cid) counts         [companydata] company         inner join [vendor] mav on company.cid = mav.cid         left outer join [customer] customer on company.vendorid = customer.vendorid                  , company.did = customer.did         ordername in ' + @name+ '         group customer.version, ordername'  exec sp_executesql @sql

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
