oracle - I have a SQL with nvl and case statement that has to be converted into Informatica expression -


i have following sql statement:

nvl(w_sales_invoice_line_fs.invoiced_qty, case nvl(w_sales_invoice_line_fs.net_amt,0) when 0 w_sales_invoice_line_fs.invoiced_qty else -1 end)

could me converting informatica expression isnull , decode(). tried following , gives out parsing errors:

iif(isnull(ext_invoiced_qty),  decode(ext_net_amount, iif(isnull(ext_net_amount),0,ext_net_amount) =0, ext_invoiced_qty, -1), ext_invoiced_qty)

to note:

w_sales_invoice_line_fs.invoiced_qty = ext_invoiced_qty w_sales_invoice_line_fs.net_amt = ext_net_amount

your sql statement little bit strange. let's analyse it:

  w_sales_invoice_line_fs.invoiced_qty != null =>  w_sales_invoice_line_fs.invoiced_qty   w_sales_invoice_line_fs.invoiced_qty = null , w_sales_invoice_line_fs.net_amt = null => w_sales_invoice_line_fs.invoiced_qty (but it's null)   w_sales_invoice_line_fs.invoiced_qty = null  , w_sales_invoice_line_fs.net_amt != null = > -1

it seems need have same output:

  decode ( true,     not isnull( ext_invoiced_qty ),  ext_invoiced_qty ,       isnull(ext_net_amt), null,      -1)

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; } ...
