mysql - Mixing two tables together -


i have 2 tables

db2:

id, db1id, text, count_db1

db1:

id, text

db2 above created by

select *, count(`db1id`) count_db1 `db2` group `db1id` order count_db1 desc

so last column added , whole output sorted descendingly count_db1.

db1ids ids of db1. want to

select * db1

ordered value of count_db1 in db1. if id of db1 not existant in db2 db1id should added end of list(ie assigned value of 0 count_db1).

example:

db2: id, db1id, text, count_db1 1,4,hello,5 2,4,hello,5 3,4,ho,5 5,4,yeah,5 6,4,no,5 4,3,no,1  db1: id, text 3, yeahright 4, whatever

so in db2 db1id 4 occurs 5 times, db1id 3 occurs 1 time. order entries of db1 such id 4 comes before id 3. result should be:

  1. whatever
  2. yeahright

a simple left join count should want;

select db1.* db1 left join db2   on db1.id=db2.db1id group db1.id, db1.text order count(db2.id) desc

an sqlfiddle test with.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
