sql server - convert SQL full text index statement originally in double qoutes for vb, with c# -


i have inherited sql statement written vbscript need convert use in c#. written full text index search in vbscript , classic asp.

the problem believe double quotes. here original statement...

select * ejn_expandeddescriptions ft_tbl inner join containstable(ejn_expandeddescriptions, searchindex, '""" & txtformdesc & "*""', 50) key_tbl on ft_tbl.id = key_tbl.[key] att10='current' order key_tbl.rank desc

notice use of double qoutes in section...

'""" & txtformdesc & "*""'

i need convert string c# , pass parameter, @txtformdesc, string must include asterisk. here sample code understand should way fix (from https://docs.microsoft.com/en-us/sql/t-sql/queries/contains-transact-sql...)

use adventureworks2012;   go   select name   production.product   contains(name, '"chain*" or "full*"');   go

from code assuming there needs double quotes in statement. have tried use "/ in replace of of double quote in c# not let me. tried using following code...

select txtitema ejn_expandeddescriptions ft_tbl inner join containstable(ejn_expandeddescriptions, searchindex, ' @txtformdesc" + "*' , 50) key_tbl on ft_tbl.id = key_tbl.[key] att10 = 'current' order key_tbl.rank desc

this still results in error.

if use statement without asterisk, works on single words not more 1 word, (which above statement supposed do).

select txtitema ejn_expandeddescriptions ft_tbl inner join freetexttable(ejn_expandeddescriptions, searchindex, @txtformdesc, 50) key_tbl on ft_tbl.id = key_tbl.[key] att10='current' order key_tbl.rank desc

i have tried no luck...

select txtitema ejn_expandeddescriptions ft_tbl inner join containstable(ejn_expandeddescriptions, searchindex, '@txtformdesc" + "*' , 50) key_tbl on ft_tbl.id = key_tbl.[key] att10 = 'current' order key_tbl.rank desc

i need create statement works in c# able pull off corrected conversion original form in vbscript, work in c# string accepting paramater @txtformdesc, using asterisk.

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
