ms access - query returns a value, but ADODB.Recordset.fields("Value") = null -


i trying collate data 2 different servers, 1 sql , 1 access. admit access sql little shakey, 1 doesn't make sense me.

i firing query @ access database, have configured queries in both servers return single values function.

the query follows

bookquery =  "select sum(dbo_wipjobpost.lqtycomplete) [sum]" & vbcr & _ "from dbo_wipjobpost" & vbcr & _ "where dbo_wipjobpost.lmachine '**" & machno & "**'" & vbcr & _ "and dbo_wipjobpost.trndate between #" & format(stime, "dd-mmm-yyyy hh:mm:sss") & "# , #" & format(atime, "dd-mmm-yyyy hh:mm:sss") & "#" & vbcr & _ "or dbo_wipjobpost.lworkcentre '**" & machno & "**'" & vbcr & _ "and dbo_wipjobpost.trndate between #" & format(stime, "dd-mmm-yyyy hh:mm:sss") & "# , #" & format(atime, "dd-mmm-yyyy hh:mm:sss") & "#;"

when run query directly against access database number returned under column "sum". in application calling automatically using function puts query database , column heading interested in

bstring = onerecord(bookquery, "access", "sum")

function onerecord(query string, db string, field string) 'function return single cell recordset  dim conn adodb.connection dim rec adodb.recordset dim constring string  constring = selectdb(db)  set conn = new adodb.connection set rec = new adodb.recordset  'open con string , run query conn.open constring  set rec = conn.execute(query)  'check records exist if not rec.eof  'return result onerecord = rec.fields(field) rec.close  else msgbox "no records" norecords = true end if  ' clean  if cbool(conn.state , adstateopen) conn.close set conn = nothing set rec = nothing  end function

for reason once query , field placed in line

onerecord = rec.fields(field)

the highlighted prompt returns null. have tested query prints in 1 record function , works, have heading sum, reason doesn't work.

i think wildcards around machno, if specify distinct machine onerecord code works, wildcards not (i working off of older databases , random spaces in machine names etc common.)

can me take final steps this? feels close!

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

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
