sql - Why would my Access 2007 query suddenly become not updateable? -

-

i have query in access 2007. it's worked fine months, i'm getting "the recordset not updateable" error. thinking error must have been caused recent change, went archived versions (that definitley worked) - they're chucking out same error. table updatable; indeed, query on same table works fine. have happened break query? code follows:

    select prospects.company, contactnames.*, iif([prospects]![key contact]=[contactid],true,false) [key contact], prospects.status contactnames inner join prospects on contactnames.companyid=prospects.id (((prospects.status) not "duplicate"));

any appreciated. thanks, oli.

if using linked odbc tables, need include primary key field(s) tables in query if want query updateable. here potential "gotchas":

  • access may not recognize primary key fields correctly in linked odbc table; (always?) access picks first unique index finds table (based on alphabetical order of index name) , assumes index primary key
  • adding replication tables in ms sql server (and perhaps other rdbms's) add guid column unique index; along above point, can cause access think linked tables have different primary keys do
  • changes made design of odbc linked tables not automatically reflected in access; linked odbc tables can refreshed via tools --> database utilities --> linked table manager... (among other ways)

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...
