sql server - SQL extract data to Excel using Powershell -


i want extract data sql server new excel file using powershell . small data set code works tables has more 100.000 rows , take ages. reason why don't use utility in sql server because want extract mutilple tables. there way optimize script export big tables excel? or there way this?

i'm using following script

## ---------- working sql server ---------- ##  ## - sql server table data: $sqlserver = 'server'; $database = 'database'; $sqlquery = @'   select top 10 *   database.dbo.table   '@;  ## - connect sql server using non-smo class 'system.data': $sqlconnection = new-object system.data.sqlclient.sqlconnection; $sqlconnection.connectionstring = ` "server = $sqlserver; database = $database; integrated security = true";  $sqlcmd = new-object system.data.sqlclient.sqlcommand; $sqlcmd.commandtext = $sqlquery; $sqlcmd.connection = $sqlconnection;  ## - extract , build sql data object '$datasettable': $sqladapter = new-object system.data.sqlclient.sqldataadapter; $sqladapter.selectcommand = $sqlcmd; $dataset = new-object system.data.dataset; $sqladapter.fill($dataset); $datasettable = $dataset.tables["table"];   ## ---------- working excel ---------- ##  ## - create excel application instance: $xlsobj = new-object -comobject excel.application;  ## - create new workbook , sheet (visible = 1 / 0 not visible) $xlsobj.visible = 0; $xlswb = $xlsobj.workbooks.add(); $xlssh = $xlswb.worksheets.item(1);  ## - build excel column heading: [array] $getcolumnnames = $datasettable.columns | select columnname;  ## - build column header: [int] $rowheader = 1; foreach ($colh in $getcolumnnames) { $xlssh.cells.item(1, $rowheader).font.bold = $true; $xlssh.cells.item(1, $rowheader) = $colh.columnname; $rowheader++; };  ## - adding data start in row 2 column 1: [int] $rowdata = 2; [int] $coldata = 1;  foreach ($rec in $datasettable.rows) { foreach ($coln in $getcolumnnames) { ## - next line convert cell text only: $xlssh.cells.numberformat = "@";  ## - populating columns: $xlssh.cells.item($rowdata, $coldata) = ` $rec.$($coln.columnname).tostring(); $coldata++; }; $rowdata++; $coldata = 1; };  ## - adjusting columns in excel sheet: $xlsrng = $xlssh.usedrange; $xlsrng.entirecolumn.autofit();  ## ---------- saving file , terminating excel application ---------- ##  ## - saving excel file - if file exist delete save $xlsfile = ` "c:\path\file.xls";  if (test-path $xlsfile) { remove-item $xlsfile $xlsobj.activeworkbook.saveas($xlsfile); } else { $xlsobj.activeworkbook.saveas($xlsfile); };  ## quit excel , terminate excel application process: $xlsobj.quit(); (get-process excel*) | foreach ($_) { $_.kill() };  ## - end of script - ##

there's simple magic make lot easier, , that's copy/paste. can convert datatable tab delimited csv, copy clipboard, , paste excel. i'll ignore sql part, since seem have in hand.

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
