sql - add parameters to select case db2 -


i have following select statement: 

 select (case when age_years >= 18 , age_years < 30 '18-29'                   when age_years < 50 '30-49'                                             when age_years < 70 '50-69'                                              when age_years < 100 '70-100'                                          end) age_range, count(*) num                                       info                                                  group (case when age_years >= 18 , age_years < 30 '18-29'             when age_years < 50 '30-49'                                             when age_years < 70 '50-69'                                             when age_years < 100 '70-100'                                           end)                                                                         order min(age_years);

output

 age_range          num    ---------+---------+----- 18-29              828    30-49             2510    50-69             2014    70-100             649

now want add column percentage of male/female parameter "gender" (0 or 1) in "info" , parameter of table "paytb", sum of transactions "acaureq_aureq_tx_dt_ttlamt". both tables share cont_id. should this:

 age_range          num      gender       transaction amount average ---------+---------+--------------------------------------------------- 18-29              828        50%         2000 $ 30-49             2510        ??          ???  50-69             2014        ??          ??? 70-100             649

i think should you. adding more aggregates. changed counts, because assumed there 1 many relationship between new table , client table.

 select (case when age_years >= 18 , age_years < 30 '18-29'                   when age_years < 50 '30-49'                                             when age_years < 70 '50-69'                                              when age_years < 100 '70-100'                                          end) age_range,               count(distinct <pk_client_info>) num ,              sum(case when client_info = 'male' 1 else 0 end) / count(distinct <pk_client_info>) 'male/female'              ,sum(acaureq_aureq_tx_dt_ttlamt) / count(*) 'total-amount avg'          info c          left paytb t          on c.cont_id = t.cont_id                                                  group (case when age_years >= 18 , age_years < 30 '18-29'             when age_years < 50 '30-49'                                             when age_years < 70 '50-69'                                             when age_years < 100 '70-100'                                           end)                                                                         order min(age_years);

python - How to insert QWidgets in the middle of a Layout? -

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
