.net - Linq to SQL with UDF - paging exception -

-

good day. got table result udf in ms sql 2008r2 base , mapped class "applicationgroupsresult"

alter function [dbo].[netsqlazman_applicationgroups] () returns table return select     dbo.[netsqlazman_applicationgroupstable].*         dbo.[netsqlazman_applicationgroupstable] inner join                       dbo.[netsqlazman_applications]() applications on dbo.[netsqlazman_applicationgroupstable].applicationid = applications.applicationid    [function(name="dbo.netsqlazman_applicationgroups", iscomposable=true)] public iqueryable<applicationgroupsresult> applicationgroups() { return base.createmethodcallquery<applicationgroupsresult>(this, (methodinfo) methodbase.getcurrentmethod(), new object[0]); }

now want take few records:

            var query = context.applicationgroups();              totalrecordscount = query.count();              query = string.isnullorwhitespace(sortby)                         ? query.orderby(x => x.applicationgroupid)                         : query.orderby(sortby);              return query                 .skip(pagenumber*queryrecordscount)                 .take(queryrecordscount)                 .toarray();

and got exception: "this provider supports skip on ordered queries returning entities or projections contain identity columns, query single-table (non-join) query, or distinct, except, intersect, or union (not concat) operation."

does linqtosql udf supports paging? if wrong?

here's problem: "where query single-table (non-join) query".

the query in udf inner join table. in order skip work, there must pretty "stable" result set ensure can accurately select chunks of , not pull random data every time.

by way, udf example purposes? it's looks can expressed in linq in typed manner, have wonder why want use udf?

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
