c# - Use XMLHttpRequest to execute a SQL Query and return the results.. help! -

-

i'm building web app company run query every few seconds against sql server, , data returns database restoring , how % complete is. have query set , works fine.

what want on web form, have "div" element contain % complete of database restore, , have update every few seconds using javascript timer object:

setinterval(function, interval)

i figure need use xmlhttprequest send request web server run sql query. on right track? how start this?

my sql query below:

use master select der.session_id, der.command, der.status, der.percent_complete, * sys.dm_exec_requests der percent_complete > 0

just create regular asp.net page target ajax request. in page processing (authentication etc. if necessary) , db query usual. result may give javascript request via response.write(). on client side, parse request , display results.

this rough overview. consider using api apropriate data / infrastructure. may take account things security, json/xml etc.
