concatenation - How to concatenate rows together until a condition is met in Teradata 13 -


i have following table:

id_clt  steps             inner rank 61081   round_sig_1               1 61081   ar_ok                     2 61081   abs_ft                    3 61081   round_sig_2               1 61081   tech_dispatch             2 61081   ar_ok                     3 61081   ret_ft                    4 61081   ret                       5 61081   closed                    1

i want concatenate steps until inner rank reset 1,in other words, want following output:

id_clt  steps                                           inner rank 61081   round_sig_1 ar_ok abs_ft                             1 61081   round_sig_2   tech_dispatch ar_ok reft_ft ret        1 61081   closed                                               1

concerning input table, simplified version of query use is:

select alpha.id_clt ,               alpha.steps,              rank() on (partition alpha.id_clt             order alpha.rnk            reset when (alpha.steps 'round%' or  alpha.steps 'closed')) seqq (  select  id_clt, steps, rnk) alpha

where rnk column orders different steps in time given id_clt

is there idea how can proceed obtain result? have tried many tricks rank(), row_number() , reset syntax didn't work...

thank in advance.

regards.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
