sql server - How to multiply a large number in sql with out getting a "overflow error " error -


i know maybe silly question; how multiply large numbers in sql server without getting error:

arithmetic overflow error converting expression data type int

i need take column contains list of 6 digit client numbers.

e.g. 123456, 123457 , make 1234560000000, 1234570000000 & etc.

this tried doing.

update account set sclientidno =  sclientidno * 100000000

but end overflow error. appreciated.

edit: forgot mention column contained client numbers had varchar data type.

i can suggest use numeric type this:

declare @a numeric(14, 0) = 123456 select  @a * 100000000

note use 14 requirement can use bigger values precision.

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; } ...
