greendao and sqlite triggers -



greendao and sqlite triggers -

i tried utilize code below ensure referential integrity in database, seems not working greendao. can still delete records. on other hand, when seek delete in sqlitemanager, trigger raised , delete operation fails.

devopenhelper helper = new daomaster.devopenhelper(this, common.dbname, null) { @override public void oncreate(sqlitedatabase db) { super.oncreate(db); db.execsql("create trigger grupe_artikli before delete on groups "+ "for each row begin "+ "select case " + "when ((select id_group products id_group = old._id) not null) "+ "then raise(abort, 'error') "+ "end; end;"); daosession session = new daomaster(db).newsession(); }

does greendao back upwards triggers, or there method maintain database referential integrity?

greendao has no built-in trigger support. however, cannot think of reason why approach should not work. greendao not hijack database or something, should able work straight database wouldn't utilize greendao @ all.

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...
