sql - Update xml tag in Oracle - joining another table -


i found following link useful, ask further it

update xml tag in clob column in oracle

using same data in previous post:

create table tmp_tab_noemail_test (sce_msg clob); insert tmp_tab_noemail_test values ( '<energy xmlns="http://euroconsumers.org/notifications/2009/01/notification">         <gender>m</gender>     <firstname>mar</firstname>     <name>van hall</name>     <email/><telephone>000000000</telephone>     <insertdate>2013-10-09</insertdate> </energy>');  update tmp_tab_noemail_test p1  set p1.sce_msg = updatexml(xmltype(p1.sce_msg),   '/energy/insertdate/text()','not valid',   'xmlns="http://euroconsumers.org/notifications/2009/01/notification"').getclobval();

now, if wanna table account. has column: acct_num, name, date_of_birth

how can update insertdate tag value = account.date_of_birth name tag value = account.name?

is possible do? thanks!

if correctly understood question, can extract name , rowid tmp_tab_noemail_test, join them account table, updated xml , using merge (by rowid) update in destination folder - 

create table account (acct_num varchar2(20), name varchar2(255), date_of_birth date);  insert account values(123, 'van hall', sysdate); commit;  merge tmp_tab_noemail_test t using ( select rid, updatexml(xmltype(sce_msg),         '/energy/insertdate/text()', to_char(date_of_birth, 'yyyy-mm-dd'),         'xmlns="http://euroconsumers.org/notifications/2009/01/notification"').getclobval() sce_msg     (select t.sce_msg, t.rid, t.name, a.date_of_birth             (select sce_msg, extractvalue(xmltype(sce_msg),                  '/energy/name',                  'xmlns="http://euroconsumers.org/notifications/2009/01/notification"') name,                 rowid rid         tmp_tab_noemail_test) t, account     t.name = a.name) ) s on (t.rowid = s.rid) when matched update set    t.sce_msg = s.sce_msg;

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
