greatest n per group - MySql Left Outer Join limit -


this question has answer here:

table1:

 id    value 1     2     b 3     c

table2:

 xid   value 1     1     b 1     c 1     d 1     e 2     f 2     g 2     h 2     2     j 3     k 3     l 3     m 3     n 3     o 
select     t1.id id,     t1.value v1,     t2.value v2     (select id table1) t1 left outer join     (select xid, value table2) t2     on t1.id = t2.xid

result is:

 id  v1  v2 1     1     b 1     c 1     d 1     e 2   b   f 2   b   g 2   b   h 2   b   2   b   j 3   c   k 3   c   l 3   c   m 3   c   n 3   c   o

i want limit table2, 2 rows every matched table1, below:

 1     1     b 2   b   f 2   b   g 3   c   k 3   c   l

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
