Database Issue

Hi,

I’m having a problem with writing site URL.

When I’m writing the site URL using function.php page, it is not reflecting in data base and when I’m changing the same in database directly and opens my site, then site is coming coming completely blank.

And also I’ve placed every details of database in wp-config.php properly…

I just couldn’t figure it out what’s the problem.

here is the url below…
