sql - Duplicate Checks with Multiple Values -


i doing manual duplicate checks on database, , have complicated case.

i need check duplicate rows based on value in column a, have done. however, in specific case, there might multiple records have same value column different value column e.

here original query:

select columna, count(*) totalcount tablea inner join tablea_1 on fid = hid datecreated > '2013-05-08 00:00:00' group columna having count(*) > 1 order count(*) desc

i need filter out duplicates columna columne different, or unique. have added psuedocode original query

select columna, count(*) totalcount tablea inner join tablea_1 on fid = hid datecreated > '2013-05-08 00:00:00' , columne not unique group columna having count(*) > 1 order count(*) desc

i hope makes sense.

you need group clause on columna column , having clause on distinct columne

select columna, count(*) totalcount tablea inner join tablea_1 on fid = hid datecreated > '2013-05-08 00:00:00' group columna having count(distinct columne) > 1 order count(*) desc

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...
