i have table students names , heights. want query order students higher 150cm alphabetically , students smaller 150cm in descending order of names. something this: (select * students height >= 150 order name) union (select * students height < 150 order name desc) it's not working because union mess order of rows in subqueries. know it's normal, union output set , in set order it's not important. there append? select * students order if(height >= 150, 1,0 ) desc, if(height >= 150, name, '') asc, name desc sample output +------+--------+ | name | height | +------+--------+ | | 189 | | m | 666 | | thy | 166 | | yyy | 1277 | | zz | 101 | | swq | 122 | | n | 111 | | g | 145 | +------+--------+

i'm trying create node using python bindings bundled zookeeper distribution ( src/contrib/zkpython/ ). using zookeeper-3.3.1. the pydoc create states if acl null node inherit parents acl setting parameter none causes invalid acl exception. i've taken @ parse_acls in zookeeper.c , seems conflict pydoc don't have experience py c api. if can't set acl null there other acl cause inherit parent? i had same problem , found no solution. workaround add additional step. example: import zookeeper zk parent_path = "/" stat, acl = zk.get_acl(zoohandle, parent_path) ret = zk.create(zoohandle, node_path, "", acl, 0) further tip: in zookeeper-3.3.1 zk.get() returns 512 bytes of node data. should fixed in next release (3.3.3).

i have java applet i've written , have been running quite while. in applet have bunch of jlabels use html in text content (which allowed, , has been working years). main reason use html allow line breaks in jlabels. the issue: jlabels have html in them (some don't) stopped displaying text. think might have recent java update (java se 6 update 22, on 2010-oct-12) not 100 percent sure, problems did seem start around then. maybe bug has been introduced? or feature removed? i tried jeditorpane , seemed have same issues when content html. also important note first time load applet (first time java runtime starts) works fine, if refresh webpage has issues described. does have similar issues? have insights? or doing dumb? i made simple test applet , can reproduce issues 100% regularity (remembering first time runtime loads work fine, successive refreshes cause issues): [helloworldapplet.java] import javax.swing.*; public class helloworldapplet extends japplet { ...

heysa, i have little problem im not quite @ mysql queries , don't know proper terminology question i'll roll can :) i have 2 rows in 1 table want compare if not 0 , equal. in php this: if(!empty($row1) && !empty($row2)){ if($row1==$row2){ return true; }else{ return false; } }else{ return false; } here table if that's help id | b | t | ----------- 1 | 2 | 1 | 2 | 0 | 0 | 3 | 1 | 1 | and this: select * table b=t returns 0=0 record id=2 ( don't want ) correct query should return record id=3 select * table b = t , b <> 0 , t <> 0 since we're testing b = t , know if b <> 0 true, t <> 0 true. can therefore shorten to select * table b = t , b <> 0

how can bind 2 java classes? i'm programming 3d opengl program have several different classes. know how bind classes main class, can't bind 2 separate classes together. have class terrain have list containing data terrain. need data in class called figure isn't main class. have tried bind these classes this: in terrain class have: figure fig; public void bindclasses(figure fg) { fig = fg; } and in figure class have: terrain ter; public void bindterrain(terrain tr) { ter = tr; } and in both classes call functions. shouldn't bind them , variables? @ least that's how have bound classes main class. just start off terminology. class blueprint tells how instantiated object - moment write new figure() , you've created instance, an object of class figure (often have several objects of 1 class ). when "binding" above, not binding classes, binding objects . the above code fine. convention, write sort of things setters , i...

i have query on this. please @ sample code below: uibutton *button; button.tag = 1; and int = (int)[(uibutton*)sender tag]; the first line set tag number 1 button variable, using .tag method. , in second line, used (int)[(uibutton*)sender tag]; extract , cast sender integer value. question be, difference between .tag , tag method? there should no difference. before objective c 2.0, dot methods didn't exist; these added, function shortcuts longer bracketed call. in particular code example, in first code block, button doesn't hold pointer button. you'd need call uibutton *button = [uibutton buttonwithtype:uibuttonroundedrect]; button.tag = 1; this set tag 1. second code block takes existing button , extracts tag int , indicated. better example of parallel methods be: button.tag = 1; , [button settag:1]; , or int tag = button.tag; , int tag = [button tag];
