sql server - SQL Table not locked even using tablock & holdlock -



sql server - SQL Table not locked even using tablock & holdlock -

i using sql lock on table. here query:

set transaction isolation level serializable go begin transaction select * emp waitfor delay '00:00:40' rollback transaction

now, when seek access table 'emp' somewhere else (by opening query analyzer , firing select query on emp table), still data. should not homecoming data, table locked 40 seconds.

note: i'd tried "with (tablock,holdlock)" , still not working.

how can create table inaccessible 40 seconds???

i had got answer

set transaction isolation level serializable go begin transaction select * emp (tablockx,holdlock) waitfor delay '00:00:40' rollback transaction

it locks table, no 1 else can access thenafter 40 seconds.

sql sql-server database

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
