how to write query with where having multiple condition in laravel 5 - sql

Question

I am trying to update the table.
I have all values in foreach. The unique id is 'uuid'
But I would like to update if the value has been changed only. I tried to do this but no luck.
$results = DB::table('urls')
->where('uuid','=',$uuid)
->orWhere('id_media', '!=',$id_media)
->orWhere('region', '!=',$region)
->orWhere('page', '!=',$page)
->orWhere('audience', '!=',$audience)
->update(array(
'id_media' => $id_media,
'region'=>$region,
'page'=>$page,
'audience'=>$audience
));
what would be the laravel way for below query.
update my_table set
my_col = 'newValue'
where id = 'someKey'
and my_col != 'newValue';

Answer 1

try this.
find more in https://laravel.com/docs/5.2/queries#updates.
DB::table('my_table')
->where('id', 1)
->where('my_col', '!=', 'newValue')
->update(['my_col' => 'newValue']);
In your particular case, you should use this:
DB::table('urls')
->where('uuid', '=', $uuid)
->where(function ($query) use ($id_media, $region, $page, $audience) {
$query->orWhere('id_media', '!=', $id_media)
->orWhere('region', '!=', $region)
->orWhere('page', '!=', $page)
->orWhere('audience', '!=', $audience);
})
->update([
'id_media' => $id_media,
'region' => $region,
'page' => $page,
'audience' => $audience
]);
The last would produce something like this:
update my_table set
my_col = 'newValue'
where id = 'someId' and
(my_col1 != 'newValue1' or my_col2 != 'newValue2' or .. );
