Importing an Excel spreadsheet into SQL Server - trouble with data types -


i have imported excel spreadsheet sql server 2014 database , 1 of data types miscalculated. in excel, field date, sql server changed nvarchar. it's odd because there other dates in spreadsheet converted semi-correctly ("date" in excel converted "datetime" in sql). know turning off "prevent saving changes..." check mark doesn't help. plus learned through looking @ questions here on stackoverflow not recommended, don't want it. did try it, though, , still didn't change data type. reason, when try force change data type "nvarchar" "datetime", sql won't it.

does have ideas why sql change data type , not let me change back? also, why sql change "date" data type excel "datetime" , not leave "date"? in advance responses.

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; } ...
