i have composite-list-list partitioned table 19 columns , 400 million rows. once week new data inserted in table , before insert need set values of 2 columns null specific partitions. obvious approach following column_1 partition criteria: update blabla_table set column_18 = null, set column_19 = null column_1 in (value1, value2…) of course awfully slow. my second thought use ctas every partition need set 2 columns null , use exchange partition update data in big table. unfortunately wouldn’t work because it´s composite-partition. i use same approach subpartitions have use cats 8000 times , drop tables afterwards every week. guess not pass upcoming code-review. may has idea how performantly solve this? ps: i’m using oracle 11g database. pps: sorry bad english….. you've ruled out updating through ddl (switch partitions), lets dml consider. i don't think it's bad update table heavily partitioned. can split update in 8k mini updates (each single

so have 2 access databases, let's call them mydatabase , anotherdatabase. in anotherdatabase there crosstab query. want results query produces mydatabase without making modifications anotherdatabase or query itself. want mydatabase enitrely self-sufficient in sense databases interacts not have modified. could give me advice on how approach this? use linked table manager link tables in anotherdatabase mydatabase . can have query anotherdatabase in mydatabase , use that. in external data tab (in mydatabase ), click button says import access. except, instead of importing table, click radio button says "link data source creating linked table". follow wizard , should set. you need link tables require query. option write vba code in mydatabase instantiates connection anotherdatabase , queries it, think linking tables better solution less hassle

i creating code generator go through each web methods of api (asmx web service) cannot figure out how reference web reference in .tt file <#@ assembly name="myapi" #> will not work compiling transformation: metadata file 'myapi' not found currently work around create .dll wsdl , can reference in .tt no problem: <#@ assembly name="c:\myapi.dll" #> is there way reference web references directly t4 without having make .dll s out of them? you can't directly(easily anyhow) reference current project's files in t4 generator. have use system.reflection , or envdte unless want access file directly not reference text file... can have system.io read file via relative path.

i trying perform 'clean' submit, i.e. submit invoked after removing hidden divs form field. since feature going use more often, shifted code extend-part: $.fn.extend({ bindcleansubmit: function() { $(this).submit( function(event) { event.preventdefault(); $(this).find("div:hidden").remove(); console.log("trying commit..."); return true; }); } }); now, divs removed, console event triggered @ end submit has not performed. do problem here? i'm not sure trying preventdefault() , if remove bindcleansubmit() , hidden divs removed form , submitted normally. given following html: <form id="myform" method="post" action="/"> <input type="text" name="displayedinput" value="1"/> <div style="display: none"> <input type="text" name="hiddeninput" value="1"/> </d

i have extension method string want available on every code behind , class in solution. method sitting in particular namespace. i'd everywhere have access namespace without me having include in every class. i've used "namespaces" tag in web config include on every aspx page, not make accessible on code behind or elsewhere. so, there similar way include namespace everywhere? so, there similar way include namespace everywhere? no, afraid there isn't. if place extension method in of root namespaces in scope child namespaces. example: namespace foo { public static class extensions { public static void go(this string value) { ... } } } will in scope inside classes declared in foo.* namespaces. might put extension method in root namespace has same name project , available everywhere because classes automatically generated in child namespaces (unless change that).

i've got 2 macs , when doing ipad dev, interests me if it's possible have mac launch simulator , load app after build completed. would nice have ipad app running in simulator on 1 mac's screen , xcode , editing being done in another. i don't expect remotely possible, or worthwhile, understanding why or wouldn't possible worthwhile. indeed possible! you can transfer app ~/library/application support/iphone simulator/6.1/applications directory, reload simulator, , magically appear installed! or believe, can run app using tool ios-sim without copying simulator folder.
