sql server - SQL GROUP BY, adding a column from another table works but produces inaccurate information -


so here original query:

select batting.playerid, sum(g) 'g', sum(ab) 'ab', sum(r) 'r', sum(h) 'h', sum(doub) '2b',  sum(trip) '3b',                           sum(hr) 'hr', sum(rbi) 'rbi', sum(sb) 'sb', sum(cs) 'cs', sum(bb) 'bb',                           sum(so) 'so', sum(ibb) 'ibb', sum(hbp) 'hbp', sum(sh) 'sh', sum(sf) 'sf', sum(gidp) 'gidp',                           master.namelast, master.namefirst,      batting         join master on batting.playerid = master.playerid  master.namelast @lastname + '%'  group batting.playerid, master.namelast, master.namefirst

here new query:

select batting.playerid, sum(g) 'g', sum(ab) 'ab', sum(r) 'r', sum(h) 'h', sum(doub) '2b',  sum(trip) '3b',                           sum(hr) 'hr', sum(rbi) 'rbi', sum(sb) 'sb', sum(cs) 'cs', sum(bb) 'bb',                           sum(so) 'so', sum(ibb) 'ibb', sum(hbp) 'hbp', sum(sh) 'sh', sum(sf) 'sf', sum(gidp) 'gidp',                           master.namelast, master.namefirst, fielding.pos     batting         join master on batting.playerid = master.playerid         join fielding on master.playerid = fielding.playerid master.namelast @lastname + '%'  , fielding.pos in ('c', '1b','2b','3b', 'ss', 'lf', 'rf', 'cf', 'of', 'dh') group batting.playerid, master.namelast, master.namefirst, fielding.pos

all doing adding pos column fielding table. had sum columns on batting table totals. results have multiple pos's on fielding table relate sums, ie, has 50 games @ 1 pos, 50 @ pos. query works, numbers being returned getting multiplied few times along way (are lot larger in second query first) , getting multiple records based on pos, want one. thoughts? tried left outer join, didnt anything

the proble 1 record in master table can have multiple records in fielding table, cause query return each record in batting table multiple times. if need data fielding table, need limit single record per playerid.

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...
