SQL Server Return Order Counts for multiple Date Ranges in Same Query -


the query below attempt @ returning # of orders branch, reference both 2 month , 12 month date span in same result set. works 12 month range, duplicates 2 month count across branches rather specific branch received orders. data below.

results of query below

ref,l12_cnt,l2_cnt,l12_branch,l2_branch,l12_orderdate,l2_orderdate cust1,1,2,branch1,branch3,2016-11-01,2016-12-15  cust1,2,2,branch2,branch3,2016-10-20,2016-12-15  cust1,3,2,branch3,branch3,2016-12-15,2016-12-15

what results should since branch3 branch 2 orders.

ref,l12_cnt,l2_cnt,l12_branch,l2_branch,l12_orderdate,l2_orderdate cust1,1,0,branch1,branch3,2016-11-01,2016-12-15  cust1,2,0,branch2,branch3,2016-10-20,2016-12-15  cust1,3,2,branch3,branch3,2016-12-15,2016-12-15

2 mos query results

ref,opendate,branch 12345,2016-12-13,branch3 12345,2016-12-15,branch3

12 month query results

ref,opendate,branch 12345,2016-11-01,branch1 12345,2016-10-12,branch2 12345,2016-09-30,branch2 12345,2016-11-03,branch3 12345,2016-11-18,branch3 12345,2016-11-18,branch3

sql query:

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
