Java if statements without brackets creates unexpected behaviour -

-

why work:

if(name.equals("email_stub")) {     if(emailstub == "")         emailstub = results.getstring("text"); } else if(name.equals("fax")) {     if(fax == "")         fax = results.getstring("text"); }

but without first tier of brackets, not work , instead fail logically separate if statements. i.e. never go beyond first if statement , won't work intended.

if(name.equals("email_stub"))     if(emailstub == "")         emailstub = results.getstring("text"); else if(name.equals("fax"))     if(fax == "")         fax = results.getstring("text");

thanks.thought weird when ran issue.

because this:

if(name.equals("email_stub"))     if(emailstub == "")         emailstub = results.getstring("text"); else if(name.equals("fax"))     if(fax == "")         fax = results.getstring("text");

is this:

if(name.equals("email_stub"))     if(emailstub == "")         emailstub = results.getstring("text");     else if(name.equals("fax"))         if(fax == "")             fax = results.getstring("text");

without curly brackets, else reference first if before it.

and @hovercraft commented:

avoid if(emailstub == "") , instead if (emailstub.isempty()) or if ("".equals(emailstub)) since should never compare strings == or !=. consider use of trim() here, such if (emailstub.trim().isempty()).

see how compare strings in java?.

c# - Store DBContext Log in other EF table -

-
i want store logs in db table (imported ef code). my code looks this: public pmcontext() : base("myentities") { configuration.proxycreationenabled = false; configuration.lazyloadingenabled = false; this.database.log = s => logstore(s); } private void logstore(string message) { tlog log = new tlog(); log.description = message; log.insertdate = datetime.now; logs.add(log); savechanges(); } public virtual dbset<tlog> logs { get; set; } i cannot use savechanges() (get error "sqlconnection not support parallel transactions") , if remove line nothing stored in db table. how can fix this? i think happens during savechanges call anywhere in app, because sql generated call logged, triggers nested savechanges call tries start own transaction. and there thing: savechanges call in logstore method trigger logging itself, you'd end starting infin...
