sql server - SQL view for searching is slow -


we trying build view provides data in flattened manner backs simple search.

the challenge has been while displaying fields name, needing search across fields address don't have displayed, can still returned. address stored in address table, , there can many addresses each client record.

so thought view put main client record various addresses. resulted in duplicate rows because of join.

next, wrote query rolls these child tables , concatenates them together. makes easy search against , doesn't end duplicates. put view, it's pretty slow. i'm preferring keep view because of nature of component accessing data, however, i'm not opposed it.

can sped or going wrong way?

here's sql (t-sql, actually):

with clientbase (     select distinct client.clientid, clientnames.firstname, clientnames.lastname, clientnames.middlename,          addresshistory.address1 + ' ' + addresshistory.address2 streetaddress,          addresshistory.city, contactinfo.contact phone     client         inner join clientnames on clientnames.clientid = client.clientid         inner join addresshistory on addresshistory.clientid = client.clientid         inner join contactinfo on contactinfo.clientid = client.clientid ) select distinct vcs.clientid, vcs.firstname, vcs.lastname, vcs.middlename,                 (select stuff ((select distinct top (100) percent ';' + clientbase.streetaddress [text()]                                 clientbase                                 clientbase.clientid = vcs.clientid                                 xml path('')), 1, 1, '') streetaddress) streetaddress,                 (select stuff ((select distinct top (100) percent ';' + clientbase.city [text()]                                 clientbase                                 clientbase.clientid = vcs.clientid                                 xml path('')), 1, 1, '') city) city,                 (select stuff ((select distinct top (100) percent ';' + clientbase.phone [text()]                                 clientbase                                 clientbase.clientid = vcs.clientid                                 xml path('')), 1, 1, '') phone) phone clientbase vcs

create indexed view , try avoid unnecessary distinct clause. create indexed views

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
