sql - SINGLE_NCLOB requires a UNICODE (widechar) input file -


i have followed process:

  1. open notepad , enter text: "hello world"
  2. save ansi file as: c:\helloworld.txt

i run following query:

select * openrowset(bulk 'c:\helloworld.txt',single_clob) test

the text appears in column called: bulkcolumn.

i this:

  1. open notepad , enter text: "hello world"
  2. save unicode file as: c:\helloworld.txt

i run following query:

select * openrowset(bulk n'c:\helloworld.txt',single_nclob) test

the error is:

single_nclob requires unicode (widechar) input file. file specified not unicode.

why this?

you need double-check how saved "unicode" file. in windows / .net / sql server, term "unicode" refers "utf-16 little endian (le)". when dealing utf-16 big endian (be), referred "unicode big endian" or "big endian unicode". utf-8 utf-8.

i created file in notepad , went "save as" , selected "unicode" "encoding" drop-down , worked fine statement using:

select * openrowset(bulk n'c:\temp\openrowset_bulk_nclob-test.txt', single_nclob) [test];

if re-saved other encoding, got error message seeing.

i used notepad++ , in "encoding" menu selected "encode in ucs-2 little endian". ucs-2 , utf-16 identical code points u+0000 through u+ffff , there no utf-16 option in notepad++ closest thing. , yep, worked.

so somehow did not save file "unicode". if selected "unicode big endian" in notepad, not "unicode" in terms of how windows using term, if valid unicode encoding.

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
