sql server - SSIS Multiple flat files into tables with Parent Child -


this tables in sql server:

table: customer (custnum pk , auto increments)  custnum  firstname  lastname 123      bob        smith 456      john       paton 789      fred       bloggs  table: job  (custnum fk, jobnum pk , auto increments)  jobnum  custnum   item     desc 852      123      abcde    widgets 654      456      wert     more widgets 987      789      qwe      mouse mat

i have data coming 2 csv's in below format

table: customer   firstname  lastname bob        smith john       paton fred       bloggs  table: job  item     desc abcde    widgets wert     more widgets qwe      mouse mat

i need import customers jobs sql tables maintain referential integrity. when job record created, needs lookup correct custnum - how do this? have found many examples doing 1 cs file, not multiple csv's. also, there no reliable key tie job rows customer table - don't think able use ssis lookup - i?

you can use ssis package feed data base.

the package it

main package

enter image description here

enter image description here result customer

custnum     firstname  lastname ----------- ---------- ---------- 1           bob        smith 2           fred       bloggs 3           john       paton

result 

jobnum      custnum     item       desc ----------- ----------- ---------- -------------------------------------------------- 1           1           abcde      widgets 2           2           qwe        mouse mat 3           3           wert       more widgets

how it:

main task:

  1. add dts customer

  2. add dts job

  3. create flow (green arrow) customer job

customer dts

  1. add connection customer file

  2. add connection customer sql

  3. sort both outputs firstname, lastname

  4. configure merge join task image enter image description here

  5. insert , configure conditional split 1 output called "new" , expression isnull(custnum)

  6. insert customer table

job dts

  1. insert connection job file

  2. insert connection customer table

  3. sort both outputs firstname, lastname

  4. configure join image: enter image description here

  5. insert connection job table

  6. sort both custnum, item

  7. insert , configure conditional split 1 output called "new" , expression isnull(jobnum)

  8. insert job table

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

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
