WhereRaw Laravel with variable

问题

I'm trying to do this query but I got an error (Malformed UTF-8 characters, possibly incorrectly encoded):

DB::table('my_table')->select(DB::raw("id"))
    ->whereRaw('UPPER(name)','=', $upper_name)
    ->pluck('id')->first();

I'm trying to add the UPPER sql function to the query. With direct sql, the query should be:

select * from my_table
where UPPER(name) = 'HELLO'

Where $upper_name = HELLO.

Simpliest Way to do that. Hope will help you

DB::table('my_table')->select('id')
    ->where(DB::raw("UCASE(name)"), $upper_name) 
    ->first();

UCASE - Convert the text to upper-case

Bah... I got it:

DB::table('my_table')->select(DB::raw("id"))
    ->whereRaw('UPPER(name) = ?', $upper_name)
    ->pluck('id')->first();
